Ask HN: Who is hiring? (April 2026)

We build geospatial AI infrastructure. Our platform lets analysts train custom object and change detection models on satellite/aerial/drone imagery in minutes, then reconstructs 3D terrain from those detections. We just shipped a planetary-scale simulation platform with Lockheed Martin powered by Unreal Engine.

If you want to work on distributed systems that run in a data center one day and an edge laptop the next, we have interesting problems. Our training and inference infrastructure is processing trillions of pixels and we deliver real world impact for our customers across defense, intelligence, and local governments.

Tech Stack: Python, Fast API, PyTorch, Postgres, Redis, Vue.js

Infrastructure Stack: Kubernetes & Docker, Linux, AWS & Azure, Azure DevOps, Terraform, ELK, Prometheus & Grafana, ArgoCD & Helm

BoWatt builds AI software for manufacturing complex hardware products like machines, medical devices or electronics. We’re a profitable, bootstrapped startup headquartered in Munich, with team members across Germany and the UK.

We’re looking for a full-stack engineer to own and ship features across our Go backend and React/TypeScript frontend, with the option to work on our AI features as well. You have to live in Germany and have the right to work here for this role.

We’re a team of eight, and more than half of us are former startup founders (deep tech, AI, psychedelics and gaming). We build closely with our customers and aim to strike the right balance between moving fast and not breaking things.

We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Current openings:

* Product Software Engineering (Quantitative Modeling)

* Program Synthesis Engineering

* Applied Category Theory Research

* Bayesian Software Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.

We’re hiring for:

Senior Systems Engineer — Capture & Materializations Design and build high-performance connectors that move data in and out of Estuary in real time. Work across APIs, databases, and streaming systems to ensure correctness, reliability, and scalability. This role is deeply systems-oriented, with a focus on data plane execution. Go and Rust are core to our stack.

Senior Systems Engineer — Control & Data Plane Own core infrastructure that orchestrates and powers Estuary’s runtime — from control plane services to distributed data processing systems. Tackle challenges in scaling, fault tolerance, and performance across a globally distributed system. Strong backend fundamentals required; Go and Rust experience preferred.

Solutions Engineer Work with the founding team to help customers use Estuary effectively. Collaborate closely with engineering and product, shape how users integrate real-time data, and feed insights back into product development.

Product Manager Own product areas end-to-end, working closely with engineering and design to shape the roadmap and deliver a great developer experience. Engage with users, translate real-world use cases into product decisions, and help define how modern data infrastructure should feel to build with.

What we’re looking for: Engineers who care about building reliable, maintainable systems and enjoy working with complex APIs and data flows. We value curiosity, clear communication, and a willingness to learn.

Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.
