Lead engineer | Fintech
Company profile
Our client is building a platform that brings banking, invoicing, and bookkeeping together in one clear, integrated experience. No more jumping between tools – just one place to manage everything that matters to small business owners.
We’re helping them find a Lead Software Engineer who’s not only technically strong, but also excited to mentor others, lead by example, and shape how the team builds and ships product.
Job description
You’ll lead a team of 4+ engineers working on core parts of the platform – from the backend services that power bank and bookkeeping integrations, to high-volume transactional flows and event-driven infrastructure. This isn’t about building internal tools – this is product that people use every day and rely on to run their business.
What you'll be responsible for:
-
Working closely with product to scope and prioritise projects (think: smarter payment flows, realtime reconciliation, scalable syncs with bookkeeping tools).
-
Defining and evolving system architecture to keep up with fast growth.
-
Coaching your team, reviewing code, and helping people level up.
-
Writing clean, production-grade code in Node.js and TypeScript.
Some of the work ahead includes:
-
Scaling event-driven pipelines to handle high volumes of financial data.
-
Designing and building integrations with Dutch banks and accounting platforms.
-
Improving monitoring and alerting across a serverless architecture.
-
Helping introduce SST to streamline deployments and developer workflows.
-
Working with sensitive data and applying best practices around security and privacy.
Requirements
You’ve led technical teams before – officially or just by naturally stepping up. You enjoy solving real problems, building things properly, and helping others do their best work.
-
Strong backend engineering skills with Node.js and TypeScript
-
Experience with distributed systems, microservices and event-driven architecture
-
Ability to mentor, guide and inspire engineers around you
-
Business-aware: you understand how technical decisions impact the product and user
Benefits
- Up to €90k
- 28 vacation days
- Travel compensation
- Education budget
