Backend Engineer, Applied AI - Ledgentic

Less than a year out of stealth, Ledgentic is already working with enterprise clients across Europe. We're scaling fast, backed by experienced angel investors who've built and sold several unicorns, and we're only getting started.

We started with Accounts Payable, where our LLM-based engine now automates over 96% of invoices end to end. Next up: Expense Management and Accounts Receivable. As we build out the platform, you'll take technical problems from idea to production, figuring out the approach, building it, testing it and making sure it works.

AI isn't a feature here

AI is embedded throughout our development process, from architecture and code to testing and documentation. We use tools like Claude Code, Codex and Cursor every day, and we're looking for someone who wants to push this way of working further.

Our stack

TypeScript, React, NestJS and PostgreSQL, with LLM-based document understanding using Gemini and OpenAI, deployed on GCP with Terraform and Docker.

What you'll do

• Build and evolve the backend of our Accounts Payable product, including VAT validation and supplier screening at scale.

• Build the technical foundation for new modules, starting with Expense Management.

• Solve data-heavy integration challenges as we connect Ledgentic with other ERP systems.

• Work across the stack when needed. We're a small team, and everyone contributes to getting things shipped.

What we're looking for

You sit at the intersection of software engineering and AI.

• 5+ years of software development experience, with genuine depth in backend systems and databases.

• You don't just follow what's happening in AI, you use it: trying new tools, experimenting with new models and building things to see what actually works.

• Comfortable taking initiative and making technical decisions without waiting for a finished specification.

• Experience with fintech, ERP or finance-heavy products is a plus.

We care more about the value you create and how you approach problems than ticking every box on a traditional requirements list.

Life at Ledgentic

We're a team of ten based in central Stockholm, working closely with the founders with short decision paths and plenty of room to influence both product and technology.

We like working together in person and expect you to spend a couple of days a week at the office. As an early member of the team, you'll have the opportunity to join our employee stock option program and share in the value you help create.
