Job description
- We are looking for a Senior Full-Stack Engineer to join the Integrations team at DataSnipper.
- The Integrations team builds the connectors that let people and AI agents work directly with the systems a business runs on — ERPs, accounting systems, general ledgers.
- We make that access simple, secure, and reliable, so our customers spend their time on the work itself rather than on getting data out of their systems
- You will work across the stack, C#/.NET on the server side, TypeScript/React on the front end, and Python for AI-powered services, building features that auditors trust with their most critical work
- This is a delivery-focused role for an engineer who is excited to make impact and grow in a team that ships fast, holds a high quality bar, and uses AI to accelerate development
- Build and maintain the connectors and services that pull data from ERPs, accounting systems, and general ledgers into DataSnipper, in C# / .NET, TypeScript, and Python
- Design the data models and mappings that turn each source system’s schema into a consistent shape our product and AI agents can rely on
- Own new connector integrations end to end: research the source system’s API and auth, build the connector and its agent tools and MCP surface, test against real customer data, and support it after launch
- Build the tooling and observability that keeps connectors reliable as source systems change their APIs underneath us
- Implement authentication and data handling controls that meet customer security expectations for access to their financial systems
- Write robust, well-tested, production-ready code, unit, integration, and end-to-end tests are part of the deliverable, not an afterthought
- Participate in code reviews as both author and reviewer, help maintain coding standards and design patterns across the team
- Participate in on-call rotation
- Use AI-assisted engineering effectively and responsibly, critically evaluating AI output
- Partner with product managers, designers, ML engineers, and QA to refine requirements, surface edge cases, and ship features
- Break down stories, estimate work realistically, and deliver against sprint commitments with limited supervision
- Contribute to technical design discussions, propose pragmatic solutions and challenge assumptions when it helps the team
Preferred experience
- Strong experience building, deploying, and maintaining APIs
- Experience with relational and document-based databases
- Strong communication and collaboration skills in English, both written and verbal
- Hands-on experience with TypeScript and a modern front-end framework
- Entrepreneurial mindset with the ability to work effectively in an ever-changing scale-up environment
- Knowledge of Event-Driven Architecture and DDD principles
- Experience with Azure and Docker is required
- Proficiency with AI-assisted engineering tools
- Minimum of 5 years of experience building applications using a modern stack built with .NET
- Passionate about high-quality coding standards and testing of code
- Experience building or integrating with AI agentic applications in production (LLM orchestration, RAG, evals, prompt engineering)
- Experience with document processing (OCR, PDF extraction, Azure Document Intelligence, layout parsing)
- Exposure to Event-Driven Architecture and Domain-Driven Design principles
- Domain experience in audit, accounting, or fintech
