Attendi | Senior Mobile Engineer | Amsterdam, Netherlands | ONSITE (hybrid) | Full-time (80–100%, ~4–5 days/week) | Visa sponsorship + 30% ruling possible

Company: Healthcare professionals spend too much time on admin when they should be delivering care. Attendi is building the Dutch healthcare sector's voice-enabled (digital) notepad: an intuitive tool for capturing and structuring medical data at the point of care. We have product-market fit and are scaling from ~100 healthcare organisations to 10x our userbase over the coming year. Our first native Android and iOS apps are already released and in daily use (https://apps.apple.com/nl/app/attendi/id6757230193), and we're looking for someone to lead their development.

Role: As our senior mobile engineer you'll own these apps end to end: building and maintaining the native Android and iOS clients, plus our open-source microphone SDKs (https://github.com/attenditechnology/attendi-android and https://github.com/attenditechnology/attendi-ios).

Stack: Kotlin (Jetpack Compose) on Android, Swift (SwiftUI) on iOS.

Apply: https://attendi.recruitee.com/o/senior-native-androidios-mob... - or email omar [at] attendi [dot] nl with something you've shipped. Mention HN.

Quin | Founding Engineer (CTO for the right person) | REMOTE (US), preference for Bay Area (tech), Chicago (consumer), or NYC (finance) | Full-time

Quin is an agentic platform to (finally!) solve personal finance for people. It is a consumer-focused company.

https://iamquin.ai

I spent 13 years in private banking and have been working on Quin alone for about 15 months. I built 6 different prototypes to test different approaches. I've spent the last few weeks working with testers on the latest version and solidifying GTM. I need someone to take over engineering with a focus on building the backend and data layers that will support our agentic approach to personal finance.

Georgetown. UCLA (MBA). Ex-JPMorgan.

Traction: Prototype with testers

The role: You're the first engineering hire. This is about shipping the workflows that will become the product that users will trust and the data layer that can support an agent in the future.

You'll own backend architecture decisions from day one. Contract-first development (TypeScript contracts repo as source of truth), FastAPI, Supabase/Postgres, Groq for LLM inference. The stack is clean and the codebase is small.

Who I'm looking for: A full-stack engineer with a preference for backend. 5+ years backend engineering; Python / FastAPI preferred. Strong data modeling instincts — you've designed schemas that had to scale. Experience with multi-tenant data architectures. Comfort operating without process. Finance domain familiarity a plus, not a requirement. Comfort and experience using AI tools and incorporating new ideas quickly.

For the right person, this is an opportunity to take a CTO/co-founder role and define the full technical path.

Comp: Salary post-raise and meaningful equity. TBH, finding this role (either version) will be important for rasisng capital given that I do not have a technical background and fintech is complicated by regulations. I'm ok with part-time in the meantime if that's what it requires.

Email quin@iamquin.ai with the primary reason this interests you and the top two reasons why you should be considered (don't worry about a resume at this point).

Founding Senior (AI/Software) Engineer | NYC | https://www.l2labs.ai/

L2 Labs is a brand new applied AI lab building machine intelligence for data integration and interoperability. We're fast growing: we closed a pre-seed funding round, established partnerships with Cornell and NYU, and secured a large enterprise customer in less than 3 months. We are a team of hard-working researchers and engineers who are obsessive about intricate, greenfield data problems - we love whiteboarding, spinning up experiments, ordering pizza, and suddenly it’s 2am and we've actually solved something. We build impactful products + publish in A* research venues.

We are currently seeking Founding Senior SWEs, with very meaningful upside in the form of a generous equity package + working alongside skilled engineers and PhDs from top universities. To learn more/reach out, email me at andrew@l2abs.ai.

Return | REMOTE | BESS Optimization Developer (Python) | Full-time

Return (https://return.energy) is hiring a developer who will build the software that powers our BESS optimization algorithms. Return’s main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.

While we employ over 130 people, our teams are deliberately small. You will join the Optimizer Quant team, which builds the algorithms that decide when and how our batteries charge and discharge. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, and construction.

We expect you to be strong in Python and comfortable with APIs and backend fundamentals, cloud, Docker, and basic DevOps. You should be able to reason about system design and architecture, and to build and operate reliable data pipelines. A working understanding of optimization, time-series and forecasting, and the statistics behind quant work will help you move fast and ask the right questions.

Our tech stack/toolset is straightforward: Python, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, self-hosted + cloud compute. We tend to keep meetings to a minimum in order to provide at least five hours of uninterrupted coding time per day. We practice code reviews and apply automated and manual testing. Our platforms are often deployed multiple times per day.

The team includes people who have co-founded several companies and/or have experience with remote development teams since 2008. They will personally help you through most of the recruiting process (there is no recruiter involved).

Tetsuwan Scientific | Software Engineer | San Francisco (SoMa) | ONSITE | Full-time | $140K–$180K + equity | https://tetsuwan.com

We work with robots that run biology experiments. The robots are accurate, but programming them by hand takes so long that most labs don't bother. So we wrote a compiler and visual editor a scientist can use. They describe their protocol in plain language, we parse it into a structured format, and compile that to optimized code. Our end goal is to build the infrastructure for autonomous science and a centralized cloud lab. Short demo: https://tinyurl.com/mrx63phb

The team is three software engineers, an automation engineer, the founders, and soon a designer. The codebase is one monorepo containing an OCaml compiler, Python backend services, and a TypeScript/React editor. The challenges come in the form of eliciting scientific context and tacit knowledge and in the fact that a protocol has to deterministically run correctly.

We are looking for at least 3 years of experience. OCaml isn't a requirement, just a willingness to learn it. Nice if you've done DSLs, compilers, life sciences or lab automation, an ML-family language, or LLM parsing and evals.

Apply: https://jobs.ashbyhq.com/tetsuwan/ad583fec-dc0a-4b6c-8171-41...

We are hiring full-stack and applied AI engineers, as well as a UI designer, for in-person roles in NYC.

We are a seed-stage start-up, still in stealth (but already with an acquisition offer!), backed by tier-1 VCs and many of the most prominent experts in legal technology. We are working with several of the best law firms in the world. We have strong customer demand and need people to help us fill it. We are committed to improving access to justice.

We are hiring a small team of extremely talented, motivated, intense, and interesting people to solve the most difficult and important problem in legal tech: high quality answers to legal questions. Expect market-leading compensation, including meaningful equity ownership. Please send your resume to contact[at]ashmere.com.
