About the role

We care less about titles and more about mindset and attitude. We’re looking for mid-strong to senior engineers who are ready to grow fast and make a real impact. What matters most isn’t years of experience, but a strong foundation, curiosity, and the drive to level up quickly.

You’ll work on PaymentIQ, a SaaS payment orchestration platform that helps merchants centrally manage, optimise, and scale payment flows across providers and markets. Through a single integration, PaymentIQ connects merchants to more than 300 payment service providers, reducing the cost and complexity of adding new providers, supporting expansion into new markets, and enabling flexible checkout experiences. The team brings deep familiarity with payment orchestration in both PSP and merchant environments.

AI-First Engineering

We take an AI-first approach to engineering. Every engineer gets full access to a broad range of AI capabilities and is expected to use them to move faster, raise code quality, and reduce repetitive work. AI is part of how we build — not an optional add-on.

• GitHub Copilot Enterprise: premium chat, agentic coding agents, and automated code review across the IDE (JetBrains and VS Code), GitHub.com, and the CLI.
• Frontier models on tap: the latest Claude (Opus, Sonnet, Haiku) and GPT families, selectable per task with no individual quotas to worry about.
• Coding agents: delegate larger refactors, test generation, and investigation work to autonomous agents, with human review on every PR.
• Build your own tooling: we encourage engineers to write their own scripts, agents, and MCP integrations to automate the boring parts of the job.

Key responsibilities

• Build & Ship: Design, implement, and maintain features in the PaymentIQ platform, from PSP integrations to core orchestration logic, with a focus on clean, well-tested code.
• End‑to‑End Ownership: Take features from design through production and beyond — including monitoring, troubleshooting, and iterative improvement.
• Quality First: Contribute to code reviews, and help raise the bar for engineering quality across the team.
• Production Readiness: Investigate and resolve production issues, with the discipline to prevent recurrence through tests, documentation, and platform improvements.
• Continuous Improvement: Contribute to documentation, technical debt reduction, and workflow improvements — we actively support technical initiatives that strengthen the platform.
• Collaboration: Work closely with product, integrations, and delivery teams to translate merchant needs into solid technical solutions.

Requirements

• Experience: Around 3–4 years of active development experience.
• Java Foundation: A solid grasp of Java fundamentals and the ability to write clean, maintainable code.
• Product Mindset: Genuinely curious about the product, eager to understand how things work at a deeper level, and motivated to make an impact beyond writing code.
• Independence & Teamwork: Able to work both independently and as part of a team.
• Ownership: Comfortable digging into documentation, finding answers, and taking ownership of your work.
• Problem Solver: You enjoy developing software and solving hard problems with simple solutions.
• Language: Proficient in written and spoken English (work is done in English).

Nice to have

• Experience in the financial industry, payments, or e-commerce.
• Familiarity with any part of our tech stack: Java 17–21, Spring (Boot/Security/MVC), SQL, REST/JSON, Docker, Redis, TDD, CI/CD, Web Services (REST, SOAP), Maven, MySQL, Elasticsearch.

How we work

Agile Scrum: daily standups, bi-weekly planning, regular demos, technology review meetings, and monthly retrospectives. We're committed to improving our documentation and stay flexible on workflow suggestions, while actively supporting technical improvement initiatives.

Why join us?

• A competitive compensation package aligned with seniority and experience.
• Hybrid working model — 50% in our Hoofddorp office, the rest remote, supporting a healthy work‑life balance.
• Deep, hands‑on exposure to PaymentIQ, a leading payment orchestration platform.

• A collaborative culture that values expertise, accountability, and getting things done.

• Technical interview with the team (1–1.5 hours)
