vvd | Design Engineer | Remote (work from anywhere) | Full-time | React, TypeScript, Next.js

https://vvd.world

We’re building tools for storytellers, worldbuilders, writers, and creators.

We’re looking for a Design Engineer who can design and build polished product experiences end-to-end. You should care deeply about taste, interaction, motion, and frontend craft, but also understand enough about APIs, auth, and data flow to avoid getting blocked.

We’re AI-native, but not trying to replace human creativity. We use tools like Cursor and Claude Code as leverage to move faster while keeping a high quality bar.

Strong fit if you’ve shipped real things, can go from rough idea to polished implementation without waiting for perfect specs, and have built interfaces that feel good, not just functional.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Chestnut | Senior Product Engineer | SF or Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Our colleagues across the isle do an awesome job at training the Granite model series, so we (physically and organizationally) sit in a uniquely good place to do impactful work in this space.

I am currently looking for early career scientists and engineers who are interested in LLMs and also one of {programming languages, formal methods, compilers}. Experience with Rust is a plus. Cool systems-y projects with formalizations on paper or in rocq/lean/etc also a plus. Neither is necessary, per se.

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

Saildrone is the world's leading operator of uncrewed surface vehicles (USVs), providing persistent in situ data from the most challenging ocean environments on Earth. Our fleet, ranging from the 23-foot Explorer to the brand-new 170-foot Spectre, is revolutionizing how we understand and secure our oceans. We work with global navies to deliver maritime domain awareness, partner with governments to map the seafloor in high-resolution, and collaborate with scientists to track climate change and hurricane intensification in real-time.

Maybe you saw that we recently unveiled Spectre, a new class of high-speed USV designed for strike and anti-submarine warfare[1]. Or perhaps you read about our partnership with Meta, where we completed the first-of-its-kind autonomous deep-water cable survey[2]. You might have also seen our ongoing mission with NOAA to map 13,000 square miles of the Mariana Islands[3].

Whether we are hucking drones into Category 4 hurricanes or scaling up the production of the world’s largest autonomous wingsails, we are looking for people who want to build the future of maritime autonomy.

All software positions are hybrid roles based out of our HQ in Alameda, just a quick ferry ride across the Bay from San Francisco.

In addition to software, we are also actively hiring for roles in:

* Production & Manufacturing (Composite technicians, assembly, and electronics)

* Fleet Operations (Mission managers, vehicle pilots, etc.)

* Hardware Engineering (Mechanical, electrical, and systems)

MiLaboratories | Senior Software Engineer (Biologic Discovery) | Bilbao, Spain | ONSITE | VISA | RELOCATION

MiXCR is the standard for immune analysis, cited in thousands of papers. Platforma is the OS on top — bioinformatics as self-serve, interoperable "blocks" for biologic discovery.

5 of the top 10 pharma (Moderna, Pfizer, others) run discovery with Platforma today. Goal: 10 of 10 by year-end. Hiring 4–5 engineers in 90 days. Our tools are in the methods of approved cancer immunotherapies and COVID vaccines reaching millions. The next paper citing us could be the next drug.

We merged frontend, bioinformatics, and data into one team. AI killed the silo wall. Bioinformaticians who leaned into engineering and engineers who leaned into biology now ship at multiples.

WHAT YOU'D BUILD

- Discovery pipelines: raw sequences → pre-IND leads. Antibodies, biomarkers, workflows real scientists use.

- The SDK for comp scientists: TypeScript, Tengo (a Lua-like workflow DSL — yes, you'll learn it), Rust.

- The data layer: thousands of formats reduced to one. PFrames, Parquet, DataFusion, lazy columnar everything.

WHAT WE'RE LOOKING FOR

- Strong TS in 100k-line monorepos (pnpm, Turbo). Polars > pandas. Node ≥22.

- Bioinformatics exposure or appetite to learn it month one. We can teach VDJ recombination; not curiosity.

- Tolerance for sparse docs and niche DSLs. "Fix the SDK, don't work around it."

OFFER

- €90–120k base, real ESOP, ARR-tied bonus — when we grow, you grow, in cash, this year.

- Bizkaia Special Impatriate Regime: ~15–20% effective tax. Beats London / Berlin / Amsterdam net.

- Visa, relocation, soft-landing. No HR, no take-homes. Direct line to engineering.

- Bilbao: ocean, mountains, Michelin, low cost of living, highest quality of life. Onsite — context-sharing needs same room.

Email: stanp@milaboratories.com (CEO). Subject "HN", include GitHub. I reply personally. Tell me about a scientific CLI you wrapped, a plugin SDK you built, or a Polars query that survived 50M rows.
