Senior Software Engineer (Financial Statement Suite)

The Role

We are looking for a Senior Software Engineer to join the Financial Statement Suite (FSS) team at DataSnipper. FSS is on a mission to make financial statement review error-free, fast, and intelligent for over 500,000 auditors worldwide.

We're building the next generation of FSS: a web-based, AI-powered experience where intelligent agents prepare and check financial statements, and auditors review, correct, and sign off with confidence. You'll help lead that shift, working primarily on the backend and our AI agent services, and contributing to the React web experience where it all comes together.

This is a hands-on senior role for someone who loves to build, sets a high quality bar, and wants to shape how a product is architected, not just implement it. You'll work closely with product, design, and fellow engineers, mentor the people around you, and use AI to move fast without cutting corners.

About DataSnipper

Audit and finance are still massively manual — and we’re changing that.
DataSnipper is a $1B, bootstrapped unicorn with 600,000+ users across 180+ countries, already embedded in the daily workflows of top audit and accounting firms. Now, we’re taking things further with our Excel Agent — bringing AI directly into where the work actually happens.
Unlike generic AI tools, we don’t sit on the sidelines. Our AI operates inside Excel, with access to real documents and audit evidence — meaning it doesn’t just generate answers, it does the work, with full traceability.

We’re not just applying AI — we’re redefining how audit gets done. If you want to build something category-defining at scale, this is the place.

What You Will Do

Technical Delivery

• Design and build production APIs and services, primarily in Python and C#, that power financial statement review workflows.

• Develop AI-powered agents and workflows that automate the preparation and checking of financial statements, integrating LLMs and document-understanding pipelines.

• Contribute to the React web front end, where auditors review, correct, and approve results.

• Keep results trustworthy by pairing LLMs with deterministic checks, correctness is never left to guesswork.

• Integrate with Azure and its AI services.

• Implement security controls aligned with OWASP and OWASP GenAI security guidance.

Architecture, Quality & Reliability

• Architect services and systems using well-established design principles, anticipating future use cases.

• Write robust, production-ready code that anticipates edge cases, unit, integration, and end-to-end tests are part of the deliverable, not an afterthought.

• Raise the engineering bar through high-quality code reviews, technical mentorship, and establishing best practices.

• Diagnose complex issues across services and use operational data to drive stability improvements.

• Participate in the on-call rotation and stay accountable for what you ship.

Collaboration & Impact

• Break down epics, align dependencies, and help the team navigate ambiguity.

• Partner with product managers and designers to shape solutions, refine the roadmap, and simplify technical approaches.

• Foster a culture of documentation and knowledge sharing within the team and with business stakeholders.

• Use AI-assisted engineering effectively and responsibly, critically evaluating AI output and helping the team adopt it well.

• Mentor engineers and contribute to hiring, onboarding, and levelling up the team.

What You Will Bring

Must-Have

• 7+ years of experience building applications with a modern backend stack.

• Experience with object oriented language is required. Experience with Python is preferred.

• Hands-on experience with TypeScript and a modern front-end framework such as React.

• Strong experience building, deploying, and maintaining APIs on a major cloud platform (we use Azure).

• Strong fundamentals of software architecture and system design.

• Experience with relational and document-based databases.

• A quality-first mindset, testing (unit, integration, E2E) is second nature.

• Proficiency with AI-assisted engineering tools (we use Claude Code).

• Experience with Docker and containerized deployments.

• Excellent communication and collaboration skills in English, both written and verbal.

• Entrepreneurial mindset with the ability to work effectively in an ever-changing scale-up environment.

Nice-to-Have

• Experience building or integrating AI agentic applications in production (LLM orchestration, RAG, evals, prompt engineering).

• Experience with document processing (OCR, PDF extraction, layout parsing).

• Domain experience in audit, accounting, or fintech.

• Exposure to Event-Driven Architecture and Domain-Driven Design principles.

• Experience mentoring engineers or leading technical initiatives.

What We Expect

• Ownership: You take features from refinement to production and stay accountable through bug-bashing, on-call response, and follow-ups. You don't wait to be told what to fix.

• Growth Mindset: You actively seek and give feedback, and treat reviews and pairing sessions as a chance to grow rather than to defend.

• Collaboration: You build trust with product, design, QA, and fellow engineers; you ask good questions and share context generously.

• Adaptability: You feel comfortable in a fast-changing scale-up environment, priorities shift, scope sharpens, and you help the team adjust.

• Judgment: You balance speed and quality, know when to push back, when to ship pragmatically, and when to escalate.

What We Offer

• Be part of one of the fastest-growing, profitable unicorn scale-ups in the Netherlands with a global impact

• Equity (Stock Appreciation Rights) to share the company's success and growth

• Excellent salary package, competitive for top tech talent
