The website probably hasn't been updated to reflect the effect of Trump's recent $100K fee for H1B visas.

I would believe that current statement over the website in this case.

International shops can easily do transfer visas such as L1A/L1B. O-1 visas aren't hard to obtain either.

The posting date was two days ago.

And not sure if you’re aware, but there’s like a few dozen visa categories that allow immigrants to work. The hype around H1B is entertaining though!

Standard verbiage on job listings is often not immediately updated in systems for posting jobs.

My expectation of what is true doesn't change much.

Our office is beautifully located in Mauritius. We sponsor visas and handle all relocation/immigration.

Apply: jobs@multiply.cloud

I've never seen a job here based in Mauritius; that would be a cool place to work. I'm not sure I could move to a primarily french-speaking African country but it's certainly a beautiful country

Because a primarily french-speaking African country is … ? I am not sure what is your point. Also Mauritius has significant British heritage, they even drive on the “wrong” side of the road.

I've interacted with dev teams in Mauritius. The dev culture was more Indian than it was anything else.

It's not all that that distant from India actually, if you disregard the open water between them. Wikipedia has Mauritius as ethnically "67% Indian"

I don't speak french and don't have any African family/friends. Sorry I didn't mean this as some insightful analysis of the country, just my specific needs. Really interesting job and location.

I think the key is FDE-CHALLENGE-01

Yes; post was updated after my comment

In my experience chatGPT solves the challenge handily, but it does get to the level of problem that GPT requires my code review for, so either I'm not as good at using chat as I could be or they've found the point at which someone has to prove they can actually do code review to filter; nice.

Shhh don't spoil the first filter! ;) Fun set of challenges though, they totally nerd-sniped me.

Tandem Health | Senior/Staff Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)

Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

This isn't CRUD work - it's systems programming at its most challenging.

Competitive salary, meaningful time off, yearly education budget. Our most senior engineers spend their time solving the hardest technical problems hands-on, not in meetings.

If you get excited about shaving microseconds off I/O paths and building infrastructure that simply doesn't break, we should talk. Apply here: https://storpool.com/force/senior-software-engineer-storage-...

Phosphor | NYC/Remote | Full Time | Founding Engineer | $150-225k + Equity

Phosphor builds recursively self-improving systems (via malleable software and natural language interfaces) to enable the efficient development and financing of the physical world (infrastructure, energy, real estate).

Our product is built around a powerful object model which combines document editors with proprietary programming languages for financial modeling, computable contracts, etc, in order to build one of the more unique RLHF feedback loops that we've seen to date.

A primary technical bet is that if we can productize version control properly, we can capture annotated "diffs" of user information with user-validated annotations. By doing so, we create path-dependence, which enables us to specify system-level goals for agents to solve for.

Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.

We're venture-backed by one of the best deeptech funds in the market and are hiring for roles spanning product engineers, CRDT wizards, and compiler/calculation engine leads.

Job listings can be found at the bottom of phosphor.co.

Devyce (YC S22) | UK (remote/onsite/hybrid) | Senior Frontend/Fullstack/Backend Developers | Full Time We're redesigning the business phone network from the ground up. Starting with mobile apps and a softphone, we're losing the jargon (who cares what an IVR is?) and building features customers actually want. We're getting big enough to start splitting into more focused teams and there's a few different areas that we need; our infra needs a lot of work, we have big dreams for some cool AI agent/pipeline work and there's still a lot of more fundamental phone system specific problems we need to solve.

We try to be flexible around work and don't believe in regular 60-hour weeks. One key aim of our product is to help employees maintain a healthy work/life balance (who wants to be disturbed by business calls on the weekends?) in an age of remote and hybrid work. The founders lead by example, with all of us having worked 4-4.5 day weeks at times in order to spend time with our children.

We're looking for full stack software engineers - doesn't matter if you're much stronger in either the front or back end, but you do need to be able to build all the parts of a feature - there's no "front end team" once the backend is done. There is naturally work that's much more one sided, so you won't be stuck for months on the front end if you prefer the backend, but we're still a small startup so we expect you to get stuck in and help out where you can!

You'll need to visit our London office roughly once a month.

Most supply chains are still stuck with Excel or enterprise tools that take months (and $MM) to adopt. Our mission is to lower that barrier — making it possible for any business, big or small, to access modern forecasting, inventory, and planning solutions in days, not months. We’re on our journey to democratizing supply chain technology. As our first engineer, you’ll be working with the founders (former Supply chain/tech directors at Amazon who have built key components of Amazon's supply chain) to develop the core product from the grounds up (involves application of LLMs, deep learning, and optimization). If you have mid to senior level experience in software development, have built SaaS applications, understand ML-Engineering, and love building 0->1 products, we would love to talk to you. Please reach out to us at: careers@strum-ai.com.

ToucanTix | Senior Ruby on Rails Developer | REMOTE (EU/US timezones preferred)

Your code will run the gates at zoos and theme parks across Germany and the USA.

Technical challenges that actually matter:

Multi-tenant architecture supporting 100+ venues with wildly different business logic. Offline-first POS that syncs flawlessly. Complex pricing rules (weather + season + capacity + customer type) that need to stay performant. Hardware integrations with access control and payment systems.

Erdos Miller | Data Wrangler (Part-time → Full-time growth) | Remote (US preferred, flexible otherwise)

We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.

We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role. What you’ll do

Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools. Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL). Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell). Deliver insights via live web apps where data isn’t static — it’s explorable. Tech we use Python, SQL (PostgreSQL/MySQL), S3, modal.com. Bonus: React/web dev experience to shape customer-facing real-time tools. Why you’ll like it here You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role. If this sounds fun, email ken@erdosmiller.com with your background and what excites you about wrangling data.

I worked here for a few months several years ago - justifiably let go for non-performance, it was a strange time in my life and I had a lot of distractions, it was an amicable separation.

While they expect consistent high performance, the bar is reasonable and the hours can be a bit long for some but aren't insane. Everyone at the company is smart and driven. Both founders are highly technical, very passionate, genuinely business-savvy, and great with customers. Abe Erdos is borderline polymath genius - topics like wavelet decomposition are relatively pedestrian to Abe, and he seems equally comfortable in mechanical engineering, electrical engineering, and computer science (all of which are critical to this business). Abe's also a good listener, it's easy to underestimate him and difficult to overestimate him. Ken Miller has more energy than anyone I've ever seen, a very broad and reasonably deep understanding of pretty much everything, and generally has strong opinions - if you want to challenge his roadmap, it's best to stay one step ahead of him and show rather than tell.

It's a fairly mature product, but the business still moves at a much faster pace than the rest of their industry and they constantly innovate. They stay on top of technological changes; they rarely take more than a year to adopt something new that is applicable to their products. Has the feeling of a "very stable start-up". They truly own both the hardware and data end-to-end, which is very helpful. They have expertise and ownership of every level of abstraction - they'll build Helmholtz coils in-house to calibrate instruments on custom PCBs designed and soldered in-house, while managing distributed systems from edge to datacenter, run their products at customer sites, maintain personal relationships with their customers and employees, and deal with legal action directly themselves.

If you're interested - understand that what might take 1-3 months at a large corporation is often accomplished in a few days to a week here. Working, manipulable demos are appreciated over presentations. If discussion hits a wall where it's impossible to know whether going direction A or B is correct, they will simply pick one direction to explore rather than deliberate further and they'll use that exploration to gain more information, open to backtracking and going the other direction, but only if it's profitable to do so.

Every person there has built a lot, either product or business. They focus on building things that don't suck, and they don't have much patience for things that do. So generally you won't have to worry about being forced to use crappy tools that make you miserable. There are a LOT of different personalities in the company, all strong in their own ways (some quiet, some loud, some blunt) so it's probably best if you are the type of person who can work with a variety of personalities - but this isn't a euphemism to indicate toxic personalities - if you're high energy and passionate you'll feel at home, sometimes opinions can fly fast and hot but the best results are gained by communicating clearly and decisively, not emotionally. Some employees are quieter and it's often best to be quieter with them and listen more. Keeping an emotional buffer/distance between you and work decisions made by your colleagues/bosses will help a lot. If there's loud direct criticism, it's about the work - not the person.

Most of their employees are on-location, but they integrate remote workers well enough - quite a few excellent employees work remotely and communication is good. You might miss some in-person chatter but you won't be completely blindsided (at least not much more than anyone else in a company that makes decisions faster than you can complete a story point).

When I was there, compensation was definitely reasonable - I was comfortable. It's an MCOL, but we had a competent developer in NY who stayed with the company through the tech boom years.

Thank you for writing that. It may be the most remarkable and insightful recommendation and advisory I have ever seen. And from someone who was let go, no less.
