About the role

Why the role exists

At Stonewell we work with ambitious, growing companies that run on unique ERPs and platforms and still spend too much time on manual re-entry, processing and administrative work. Your job is to put an end to part of that.

You work in practical and challenging conditions, where you often need to creatively sketch out a workflow that genuinely solves the problem. So no standard n8n or Make flows.

The role

What you will do

  • Design, build and maintain back-end automations: with platforms such as n8n where they fit, and with custom code where needed (partly based on templated code libraries etc.).
  • Integrate third-party tools and services through their APIs, with a focus on reliability, performance and security (e.g. AWS Lambda).
  • Set up and integrate (vector) databases, and apply AI components where they add value (mainly LLMs, usually without extensive fine-tuning or classic ML).
  • Take end-to-end ownership of automation workflows, from concept and implementation through to testing, deployment and iteration.
  • Document architectures, workflows and integrations for long-term maintainability and knowledge sharing.

Your experience

What you bring

  • 3+ years of experience with back-end (automation) development (Python (FastAPI), Node.js/TypeScript, Docker, etc.).
  • 1–2+ years of hands-on experience with AI infrastructure; experience with automation tools (n8n) is a big plus.
  • Comfortable with (REST) APIs and database technologies (mainly PostgreSQL (Supabase)).
  • Experience with AI-assisted coding (Claude Code etc.).
  • Experience with full-stack applications is a big plus.
  • Available during Dutch office hours (8:00–18:00 Amsterdam).
  • Fluent English; Dutch is a plus.

Bonus points

What makes you a better fit

  • You communicate professionally and clearly with clients, are responsive and reliable, and put project success first.
  • You are proactive, take ownership, are strong at problem-solving and get things done.
  • You enjoy direct communication with clients, are invested in their success and like solving real problems for successful companies.
  • You thrive in a fast-paced, high-growth startup environment with flexibility and a strong sense of responsibility.

What we offer

What you get

  • Work in a driven team of around twelve developers on impactful projects for ambitious clients in the Netherlands and worldwide.
  • Access to growth opportunities, including the potential to move up to a Team Lead or CTO role within our ventures and labels launching in 2026.
  • A high-performance environment where quality, ownership and speed are the standard, and success is shared between you, the team and our clients.
  • Work for clients where your solutions genuinely make an impact: you are involved in their success from start to finish, get to know the real business and build deep relationships with top entrepreneurs.
  • A high degree of autonomy and flexibility, including the freedom to work from wherever you perform best.
  • A team where the founders genuinely care about you: we focus on building the life you want, with win-win-win outcomes for you, our clients and the business.

The process

How your application goes

  1. Questionnaire

    A short questionnaire with the vacancy, a few minutes long.

  2. Introduction

    A 30-minute introduction to determine the initial fit.

  3. Case

    For a technical role: a technical case of 2 to 3 hours.

  4. Final decision

    A final conversation with Jason, around 45 minutes, followed by a final decision.

Frequently asked questions

The questions we hear most

  • We mostly work remote, unless you work from our office in Pakistan or South Africa. Our HQ in the Netherlands is in the works for Dutch roles (likely The Hague).

  • No. If you recognise yourself in the role and most of the points, apply. We look at what you can do and how fast you learn, not at a checklist.

  • For an acquisition role, exclusively Dutch. For development roles everything runs in English (Dutch is not required, unless the vacancy explicitly states otherwise).

  • We make sure your interests and ours point the same way. If we win you win, and the other way around. Growth moves towards more seniority and responsibility (your own team, bigger projects), up to building companies together (such as SaaS businesses). It ultimately depends on what makes your heart beat faster.
