Braiins - Fullstack Engineer / AI Engineer for BRAIINS MANAGER
Requirements
• Strong TypeScript, both ends. Node.js on the server (NestJS or equivalent) and a modern SPA framework (Angular, React, Vue). Real depth on one side, genuine competence on the other — we're not looking for someone who "also touches the frontend." • Strong TypeScript, both ends. • SQL that goes past the ORM. PostgreSQL, relational modeling, migrations, and the judgement to know when the query builder is the wrong tool. • SQL that goes past the ORM. • Hands-on experience shipping with LLMs. Tool/function calling, MCP, retrieval, agent orchestration, evals — any credible subset. Equally valid: you've pushed coding agents hard enough on real codebases to have opinions about where they break. • Git, Docker, CI. The daily toolchain, not a checkbox: readable history and clean branches, a service you can containerise yourself, and a pipeline you can fix when it goes red. Kubernetes is a plus, not a gate. • Git, Docker, CI. • Comfort with asynchronous, distributed systems. Queues, at-least-once delivery, idempotent handlers, retries and backpressure — and what each of those costs. Microservice architecture, observability stacks, time-series or telemetry data at scale. • Comfort with asynchronous, distributed systems. • REST and gRPC; a working understanding of what's underneath them. • REST and gRPC • Tests you'd defend in review — unit and integration, and the judgement to pick. • Tests you'd defend in review • Debugging as a core skill. Reading a stack trace, a slow query plan and a metrics dashboard with equal comfort. • Debugging as a core skill. • Solid grasp of algorithms and data structures. • English at a communicative level, and the self-direction a remote team needs. • English at a communicative level • Rust. We have a real Rust codebase and you can go as deep into it as you want. It is not a requirement and not something we screen on — if you come from C, C++ or Go, or simply want to learn it here, that's a welcome bonus, nothing more. • Rust. • not a requirement and not something we screen on • Python — our agent orchestration tooling lives there. • Python • Frontend craft: design systems, accessibility, bundle and rendering performance. • An interest in Bitcoin or active experience with cryptocurrencies.
Benefits
• Full-time position with flexible working hours, employee or freelance. • Indefinite contract. • For employees: 5 weeks of vacation and 3 sick days. • Fully remote, with modern offices in the centre of Prague if you want them — relaxation room, shower, parking. • Company events and the occasional Braiins brunch. • A generous budget for AI tooling, and the freedom to use it properly. • Long-term work on products used daily by industrial-scale mining operations. • Interested? Tell us what you've built — a repo, a system you're proud of, or an agent setup that actually earns its keep. We'd rather read that than a cover letter. • Do you want know more about Braiins?
