Alwin agents run multi-step audit procedures over client evidence and return finished workpapers with every number traced back to source. Humans plan, review and sign off. This is a hands-on role, most of your time goes into writing code: prototyping new agent capabilities, building the hardest parts of the platform, and getting them into production. The rest goes into making the people and systems around you better: raising the bar, mentoring engineers, and leading the technical decisions that shape Alwin. Your mission: speed up innovation, drive the quality bar, and help us build the best agentic products for audit and finance. You lead by example. Engineers across teams follow your direction because they see it work in your code, not because it is written in a document.\nWhy DataSnipper?\nThe hardest AI problems aren't about getting an answer fast. They're about getting one people can trust.\nWe believe trust is essential to how society works. Every day, we rely on information that's been independently verified, from financial statements to the products we buy, to the sustainability claims companies make. Behind that trust are audit and finance professionals who examine evidence, verify information and hold organizations accountable.\nAt DataSnipper, we build AI solutions that empower those professionals. By making evidence easier to trace and verify, we help them focus on the judgment and expertise that make their work so important.\nFor our product and engineering team, this is where things get exciting. In audit, a plausible answer isn't good enough. Every output has to be explainable and traceable back to its source. We've just launched a brand new agentic platform, Alwin by DataSnipper. AI agents running in the cloud across hundreds of documents at once, reasoning across PDF, Word and Excel, with a full audit trail behind every step. There are lots of greenfield problems ahead, and real room to shape what we build and how we build it.\nAnd we build at scale. More than 600,000 professionals across 3,000+ organizations in 175 countries rely on DataSnipper, including Fortune 500 companies, government agencies and all Big Four audit firms. In 2025 alone, the DataSnipper platform delivered more than $1.4 billion in productivity savings to is customers. Backed by a $100 million Series B led by Index Ventures, at a $1 billion valuation, and as proud members of 1% for the Planet, we care about how we grow, not just how fast.\nIf you want to build AI that professionals trust with work that really matters, this is your chance to help shape the future of audit and finance and do the best work of your career along the way.\nWhat You Will Do:\nBuild & Ship\nWrite production code every week on the most complex and critical parts of Alwin\n\nBuild proofs of concept for new agent capabilities, and take the ones that work all the way to production\n\nChampion experimentation and R&D: try emerging models and techniques, solve hard problems creatively, and turn promising ideas into reliable features\n\nShape the Alwin platform and adjacent systems by building them: the core abstractions, the reference implementations, the patterns other teams reuse\n\nContribute directly to the agent harness at the core of Alwin: the orchestration, tools, context and evaluation loops every agent runs on\n\nAnticipate where the platform needs to be in 12-18 months, and make design decisions now that minimize the cost of future change\n\nAgents in Production\nBuild agents that are reliable in a regulated domain: grounding, evaluation before release, human-in-the-loop, traceability of every action\n\nInstrument what you ship, use traces and quality metrics to find where agents fail, and fix the cause, not just the symptom\n\nJump into the hardest incidents across teams, and turn them into lasting fixes\n\nMake the trade-offs between model cost, latency and accuracy explicit, and measure them in production\n\nLead by Example\nLead technical decisions: drive the key design calls across teams, lay out the trade-offs openly, get to a decision quickly, and then prove it out in code\n\nSet the standard for code quality, testing and security through your own code and reviews, aligned with OWASP GenAI\n\nDrive AI-assisted engineering: try new tools first, show what works, and help teams adopt it\n\nShape how we build Alwin: the development process, tooling and feedback loops that let teams go from idea to tested, production-ready agent fast\n\nMentor senior engineers and grow future staff engineers by pairing, reviewing and building alongside them\n\nWork with Product to spot opportunities and differentiators against the competition, and shape the roadmap with what you have proven is possible\n\nWhat You Bring:\n10+ years in software engineering, with strong, production-grade Python, and you still write a lot of code\n\nDeep hands-on experience building and shipping agentic or LLM systems in production yourself: control loops, tool calling, context engineering, evaluation, not only prompt-and-parse pipelines\n\nA track record of building systems other engineers build on, and raising the bar across multiple teams through your own work\n\nExperience leading technical decisions and mentoring senior engineers while staying hands-on\n\nStrong fundamentals in distributed systems, software architecture and data modeling on a major cloud platform\n\nExperience with security, access control and auditability for enterprise or regulated customers\n\nProduct sense: you know which technical bets matter for customers and the business, and can make the case to Product\n\nProficient with AI-assisted engineering, and experience driving its adoption beyond your own work\n\nClear written and verbal communication, across time zones and with technical and non-technical audiences\n\nNice-to-Have\nBuilding platforms that other teams and customers build on\n\nMulti-agent orchestration or durable, long-running workflows at scale\n\nRetrieval and knowledge systems, or document processing (OCR, classification, structured extraction)\n\nWorking closely with Forward Deployed Engineers, Solution Architects and GTM teams on enterprise rollouts\n\nExperience at a scale-up going through rapid growth\n\nDomain experience in audit, accounting or fintech\n\nWhat We Offer:\nBe part of one of the fastest-growing, profitable unicorn scale-ups in the Netherlands with a global impact\n\nEquity (Stock Appreciation Rights) to share the company's success and growth\n\nPension plan with a 6% contribution on top of your base salary\n\n28 vacation days per year (full-time) to support your work-life balance\n\nHybrid work model with at least 3 days onsite in our dynamic Amsterdam office\n\nDaily, freshly prepared lunches by our in-house chef to keep you energized\n\nNS business card for easy commuting to the office if applicable\n\nAccess to continuous learning and development initiatives to grow your skills\n\nEngage with a vibrant international team spread across five global offices\n\nCompany-wide events like DataSnipper GO, where global teams come together\n\nAccess to a mental health and wellness platform supporting your wellbeing\n\nRecruitment Process\nRecruitment Screen (30 minutes, online)\n\nHiring Manager Interview (30 minutes, online)\n\nLive coding Interview (75 minutes, online)\n\nSystem design interview (60 minutes, on-site)\n\nFinal Interview (30 minutes, online)\n\nAt DataSnipper, we believe great ideas come from different perspectives, experiences, and backgrounds.
