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.
- 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.
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.
- 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.
- Hybrid role (Amsterdam)
- Travel to Athens 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
Fast-moving and straightforward
- Intro call
- Hiring manager interview
- Take-home assignment
- Conversation with senior management
