Medior full-stack developer

Why we are looking for you

Bas is growing, in the Netherlands and soon beyond. That is why we are expanding the team. You get guidance, and within a year you pick up features and bugs on your own across all of Bas, backend and frontend. How you tackle something technically is up to you. What we build and why, we decide together with the product owner and the business. Among other things, you work on making it easier for new customers to get started and on getting Bas ready for other countries.

Who we are looking for

• You want to grow towards working independently in your field.
• You like working with others towards a shared goal and you share your knowledge.
• You think from the customer’s side: movers want software that simply works.
• You stay calm under pressure and solve problems in a structured way.
• You feel responsible for how Bas grows.

What your day looks like

We work in epics: a larger piece of work that we choose together based on impact and effort, and that you finish from start to end. An outage at a customer always comes first. Every morning, in a short daily, we agree who picks up what.

Paul, the product owner, hands over the work fully specified, with prototypes, scenarios and tickets. You decide on the technical approach; Alexander reviews. Casper, co-owner, does sales and first-line support.

One or two days a week we work together at the office in the Eindhoven region, the rest of the week from home. After your first month, your first improvements are live.

What you bring

• A few years of experience with both backend and frontend, and you enjoy working on both.
• PHP with Symfony or Laravel, and PostgreSQL.
• React with TypeScript.
• You get to the bottom of a domain, such as how a payment flows from quote to the accounts.
• You trace a bug down to its cause, and you see bugs and support as normal work.
• You use AI tools as much as you like, but you can explain every line you deliver.

Our tech

• Backend: domain-driven design (DDD) with a hexagonal architecture.
• Frontend: Feature-Sliced Design (FSD).
• Always the latest versions, on our own servers, including the database and the AI models. So we are never stuck with old software or a single vendor.
• Event-driven, with live updates in the browser (Mercure).
• You build AI features in Bas yourself, such as our AI assistant for movers and our own MCP server that lets AI tools work with Bas securely.

The stack, always on the latest version: PHP, Symfony, API Platform, PostgreSQL and React with TypeScript. We work with Linear, GitLab, Claude Code and Codex.

A plus: experience with React Native (our employee app runs on Expo) or Rust.

The less fun part

Bas has years of history, and you clean up older parts when you touch them. Our checks are strict: strict typing, PHPStan and reviews. And we want a lot at once, so good coordination is part of the job.

What we offer

• From €4,000 gross per month for 40 hours (32 to 40 hours is negotiable), depending on your skills, plus 8% holiday allowance.
• A €1,000 signing bonus after your probation period. If someone referred you, you share it: €500 each. Mention who referred you when you apply.
• A one-year contract, with a permanent contract as the goal.
• 27 days of holiday, and if you fall ill, we pay 100% of your salary for both years of sick leave.
• A personal pension plan with Brand New Day (we contribute 5%), a MacBook Pro, AI coding subscriptions, a home working and phone allowance, and travel expenses.
• Guidance, but also responsibility from day one.
• A small, informal team focused on results.
