Senior Backend Engineer at DataSnipper in Amsterdam, North Holland, NL

We are looking for a Senior Backend Engineer to join the Identity & Access Management (IAM) team at DataSnipper!

In this role, you'll be responsible for designing and building core platform systems that power authentication, authorization, and access across our entire product. You’ll play a key role in shaping the architecture of our platform and enabling other teams to build on top of it.

You’ll also contribute to new initiatives such as usage and credit management systems, supporting our AI-powered product at scale.

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:

• Design and build scalable, secure IAM (authentication, authorization, access management) platform services
• Own and drive architecture decisions for backend systems
• Lead development of usage & credit management systems
• Work across teams to enable identity and access flows across the platform
• Ensure high reliability, performance, and security
• Handle ambiguous, high-level problems and turn them into structured solutions
• Collaborate with stakeholders and communicate technical decisions and risks clearly
• Participate in an on-call rotation (second line after tech support)

What you bring:

• 7+ years of backend development experience (C#, Java, Python, TypeScript, etc.)
• Strong experience with cloud platforms (AWS or Azure)
• Proven track record of building scalable, reliable systems
• Experience with system design and architecture
• Strong communication skills and ability to work across multiple stakeholders
• Bias to action and sense of ownership
• Ability to work independently on complex and ambiguous problems
• Experience with CI/CD pipelines and modern development practices
• Proficiency with AI-assisted development tools
• Wealth of experience around testing and various methodologies

Preferred Qualifications:

• Experience with Identity & Access Management systems
• Strong understanding of security and authorization models
• Experience with microservices architecture
• Familiarity with container services (e.g. Docker, Kubernetes)
• Experience working in platform teams
• Experience working in startups or scaleups

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
• Pension plan with a 6% contribution on top of your base salary
• 28 vacation days per year (full-time) to support your work-life balance
• Hybrid work model with at least 3 days onsite in our dynamic Amsterdam office
• Daily, freshly prepared lunches by our in-house chef to keep you energized
• Parking and NS card for easy commuting to the office
• Access to continuous learning and development initiatives to grow your skills
• Engage with a vibrant international team spread across five global offices
• Company-wide events like DataSnipper GO where global teams come together
• Access to OpenUp, a mental health and wellness platform supporting your wellbeing
• Friday drinks and various social activities are designed for team bonding and fun
