Backend / Full-Stack Developer (Node.js · TypeScript · Python)

O projekcie: About Thalox Sphere Thalox Sphere GmbH is a Munich-based boutique software studio inside the international Thalox group. We build custom software, AI integrations, and process automation for SMEs that don't fit the off-the-rack consulting model — Odoo, HubSpot, Supabase, n8n, and modern LLM stacks are our daily tools, but we stay technology- and vendor-agnostic and pick best-fit per client. Recent work includes the autohelden.com digital infrastructure (built in four weeks). About the role You will join a small, AI-first engineering team that spans Munich (HQ), Romania, and — newly — Poland. As Backend / Full-Stack Developer you'll build services, APIs, and integrations end-to-end — from API design through deployment to monitoring — and work side-by-side with our DevOps engineer (a parallel Poland hire). You report directly to CEO Martin Ansel in Munich; decision paths are short and there is no middle layer. Why this role - Build real products end-to-end — API design through production deployment - AI-first culture: work with LLMs and modern SaaS, not legacy - Small team, high autonomy, real impact — no corporate bureaucracy - Fully remote from Poland with a friendly CET overlap - Direct collaboration with the CEO — short decision paths - Shape the tech stack, architecture, and engineering practices from the ground up Wymagania: We are looking for a mid-level backend/full-stack developer (3–5 years) who builds services, APIs, and integrations end-to-end. Strong Node.js/TypeScript or Python core competency required, PostgreSQL hands-on, and a working understanding of containers and CI/CD. Operating model is fully remote from Poland under a B2B contract. Codzienne zadania: - Own backend services from concept to production: design, implement, test, deploy, monitor. - Build and maintain REST/GraphQL APIs and integrations with third-party SaaS and AI/LLM providers. - Design Database schemas, write efficient queries, manage migrations and Row-Level Security. - Write unit and integration tests as a natural part of the workflow. - Collaborate closely with the DevOps engineer to deploy services, read logs, and respond to alerts. - Participate in code reviews, technical discussions, and architecture decisions. - Continuously evaluate new tools and SaaS services that could accelerate the team.
