Full-Stack Developer

Coded is an early stage product company in the Netherlands. The platform is in private use by a select group of users while we build it out. We keep the details off the internet for now, so what follows describes the work and the person rather than the product. The rest we cover in a conversation. We are a small team with a high bar. The problems are genuinely hard and the standard for what ships is set deliberately high. If you like being the most senior person in the room, this is not that. If you like being surrounded by decisions that actually matter, it is. Responsibilities Own systems rather than tickets. You design them, build them, test them and stand behind them.Turn loosely defined, difficult problems into a design the rest of the team can build on.Decide what a thing must guarantee before you write it, including how it behaves when something upstream misbehaves.Leave work the next person can pick up a year from now.Raise the level around you. Review carefully, explain your reasoning, and disagree well. Qualifications Six or more years building and operating production software, a meaningful part of it at senior or lead level, with real depth on both sides of the API.You design systems, not just features. You can walk through an architecture you chose, what you traded away, and what that cost you a year later.You are fluent in the hard parts: concurrency, retries, consistency, and what your system does when a dependency fails halfway through.You have changed live systems safely. Data migrations under traffic, backwards compatible releases, and a rollback that actually worked.Performance is something you have measured and fixed, not something you have opinions about.You have carried an incident from the alert to the postmortem to the change that stopped it happening again.Security is part of how you write code, not a step at the end.You write English well enough to win a technical argument in writing. Nice to have Products with a long life, where data outlives releases and users cannot be broken by an upgrade.A background in security.Having been early somewhere before, and knowing what early actually costs. How this starts A one year contract to start, with a view to a permanent one. €70,000 to €90,000 gross per year depending on experience.Remote within European timezones.A direct line to the founder and to the decisions.
