About Change
Change has been around longer than most fintechs you've heard of. Our Dutch entity was incorporated in Amsterdam in 2010, and we have been MiFID II authorised since 2015, a decade of operating as a regulated investment firm. Today we serve around 120,000 verified users across all 30 EEA countries, with full passporting rights, and we are MiCA-authorised as one of the early CASPs in the Netherlands.

We operate an app-based investment platform built for retail investors. Our users trade cryptocurrencies, alongside CFDs on stocks, indices, currencies, gold, oil and other financial instruments — all in one place, on mobile, with the regulatory protections of a Dutch investment firm.

We are a small senior team with a practical, low-bureaucracy culture. We value ownership, clear processes, strong judgement and real operational discipline over unnecessary ceremony.

We are hiring a
Senior Engineer
who treats AI agents and tooling as a core part of the SDLC — building, shipping and operating systems with tools like Codex, Claude Code and automated reviewers as standard engineering practice.

What You Will Do

• Take ownership of one or two core domains end-to-end, execution, custody integration, market data, risk, or the trading core, and ship measurable improvements against real, regulated, money-moving systems.
• Contribute meaningfully to the Kotlin-vs-.NET architectural evaluation: prototype, benchmark, document, push back. Help us produce an honest decision rather than a fashionable one.
• Define and prove out our agentic SDLC: how we use coding agents in design, in review, in testing, in incident response. Make the patterns explicit so the rest of the team can copy them.
• Raise the engineering bar by example; clean, well-tested, observable code that other engineers want to read and extend. Become the person whose PRs others learn from.
• Partner closely with the Dutch business hub, our compliance and marketing functions, and our infrastructure team. Speed and regulatory standing are not in tension here; we expect you to deliver both.

Who We Are Looking For
Engineering depth

• 5+ years building production systems where correctness and uptime matter, ideally in finance, payments, trading or similarly demanding environments.
• Strong expertise in either the modern JVM ecosystem (Kotlin, Spring Boot, Kafka) or modern .NET (.NET, C#, ASP.NET Core), with openness to work across both.
• Comfortable with AWS, EKS, observability and infrastructure concepts; able to work confidently around cloud-native systems.
• Strong understanding of event-driven systems, idempotency, reconciliation and the realities of distributed systems in production.
• Systems thinker who can clearly communicate architecture, boundaries, data flows and constraints — for both engineers and coding agents.

AI-native, agentic-first

• You use coding agents (Codex, Cursor, Claude Code, Aider or similar) daily and understand both their strengths and failure modes.
• You have built or customised at least one real agentic workflow, tool or automation used in practice.
• You have clear judgement on where humans should stay in the loop in regulated environments. You are not impressed by demos.
• You are impressed by evals.
• You know how to provide the context, structure and guardrails agents need to operate effectively across complex tasks.

Mindset

• You communicate in writing well enough that meetings shrink. You write design docs that other engineers actually read.
• You give and take direct feedback without making it personal. You are visibly comfortable saying "I don't know" and "I was wrong".
• You want to grow your scope and impact here, not because of the title, but because you want the leverage. We will invest in that growth.

Nice to have

• Experience in a MiFID II, MiCA, PSD2 or similarly regulated environment.
• Familiarity with order management, market connectivity (FIX, REST/WebSocket exchange APIs), or crypto custody (BitGo, Fireblocks).
• Open-source contributions, particularly in the agent/MCP ecosystem.
• Greek or Dutch language is welcome but not required, we work in English.

What We Offer

• Hybrid role (Athens)
• Travel to Amsterdam and Estonia a few times a year
• Competitive base salary
• Perks and benefits
• Learning budget to keep you sharp
• Real ownership and influence
• Fast decisions, zero politics
• A real shot at growing with the company long term

Process
Fast-moving and straightforward

• Intro call
• Hiring manager interview
• Take-home assignment
• Conversation with senior management

This role is demanding but also rewarding. If you want to build, take ownership, and grow with a startup, we’d love to talk. Apply now.
