Job description

• We are hiring a senior engineer who works across our web frontend and our infrastructure — the same two codebases, in the same week. Someone who ships a product screen on Monday, changes an identity-provider flow on Wednesday, and considers those the same job
• We are looking for a broad profile rather than a specialist. The next year is mostly platform work with a user-facing edge — user management, API gateway management, payments, SEO, and a great deal of compliance, GDPR and ISO 27001
• Some of the items on our tech roadmap for the coming year. Bets are picked a cycle at a time and shared out, so you would take the ones that suit you and grow into the rest
• Product and marketing UI in React — multi-brand, WCAG AA, strong on technical SEO, fast enough to hold a performance budget
• User management and identity — Keycloak realms, organisation hierarchies, partner brokering, and the entitlement model in the app
• API gateway work in APISIX — routes, plugins and auth policy as code
• Payments and billing
• ISO 27001 and GDPR — access control, change management, audit logging, observability and alerting, consent and retention
• The infrastructure underneath — Pulumi in TypeScript, Docker Swarm on Hetzner, Cloudflare at the edge, Tailscale for all engineer and CI access
• Third-party integrations — usually the seam between two systems that were never designed to meet
• Also in daily use: Postgres and PostGIS, Valkey, ClickHouse; Vite, Tailwind and Radix; Jest and Playwright; GitHub Actions; HAProxy. Most of what we write is TypeScript, strict — though our core API is Java and Spring, and the identity layer has Java in it too, so how far you go into that side is up to you

Benefits

• Remote first
• Opportunity to work with colleagues and customers across the globe in an innovative start up environment

If you are passionate about the environment, proactive and pragmatic in getting things done, and love to work in a complex but fascinating industry where you learn every day — then this is the place for you

• Senior full-stack experience — you have owned features from the browser to the machine they run on
• A track record of taking something and running with it — a domain, a migration, a subsystem you took on, decided and stayed accountable for
• Taste. You can tell a good design from a merely plausible one, and you will reject work that functions but is not right — your own, and an agent’s
• TypeScript at strict — typed boundaries, and an instinct for when types are carrying real weight
• React beyond the client — server rendering, static generation, data loading and hydration; you know what runs where and why it matters
• Infrastructure as code — Pulumi ideally; Terraform if you are ready to pick up Pulumi
• Containers and Linux in production — not writing a Dockerfile, but debugging a service on a machine you have to SSH into
• Postgres beyond queries — backup and restore, migrations, what a schema change does under load
• Wholehearted LLM-assisted development — you use coding agents daily, have opinions about steering them, and review their output as critically as a colleague’s
• Integration instincts — third‑party APIs, webhooks, OAuth/OIDC, and patience for other people’s undocumented edge cases
• A working day that overlaps ours: based within CET ±3
• Fluent in English, our working language
• Payment systems, billing models, or PSP integrations
• Identity and API gateways in depth — Keycloak, OIDC, SAML brokering, APISIX
• Observability and alerting — Prometheus, Grafana or equivalent
• Experience in the maritime, logistics or freight industry
• Familiarity with emissions accounting frameworks (GHG Protocol, GLEC, EU ETS..)
• Compliance from the inside — an ISO 27001 certification lived through, or GDPR beyond a cookie banner
