Job description

Every great business decision starts with trustworthy financial data — yet most finance teams are stuck reconciling spreadsheets, exports, and reports across fragmented systems. The result? Endless manual checks, late nights, and a lack of confidence in the numbers.

Eagl is changing that.

We’re building the modern financial intelligence platform for accountants and controllers — one that makes financial data transparent, explainable, and instantly trustworthy. By weaving together ERP data, AI reasoning, and intuitive workflows, we help finance teams close the books faster, detect anomalies earlier, and understand every number at a glance. All in seconds, not hours.

We’re early, ambitious, and moving fast — backed by Syndicate One and exceptional founders from leading European SaaS companies.

How We Work

We believe A+ players build A+ companies. We move fast, think deeply, and hold a high bar for everything we ship, from the codebase to the customer experience. We value clarity over noise, ownership over hierarchy, and execution over talk.

At Eagl, you’ll work with people who obsess over impact, not process. You’ll have extreme autonomy, real technical ownership, and the chance to shape a product that defines how modern finance teams work.

About The Role

We’re looking for a Software Engineer excited to build the infrastructure and product experience behind the next generation of financial intelligence. This is a true 0 to 1 systems challenge ranging the entire tech stack: from backend architectures and integrations to polished interfaces and intelligent AI agents.

You’ll work directly with the founders to shape Eagl’s technical direction, design core systems, and ship the features our customers rely on. Expect to build fault-tolerant data pipelines across complex ERP environments, architect scalable multi-tenant systems, and enable AI-driven workflows that turn financial complexity into clarity.

What You’ll Do

• Create intuitive, high-quality React UIs that make complex financial data easy to understand and act on.
• Build the core data and backend systems that power Eagl’s financial intelligence layer, including integrations and high-performance ingestion pipelines.
• Develop and iterate on AI agents using LLMs and planning frameworks to automate challenging financial workflows.
• Ship end-to-end features with product and AI engineers, ensuring security, scalability, and reliability as we grow.
• Shape engineering standards, architecture, and product direction from day one.

What You’ll Bring

• Experience building and scaling backend systems in Node.js, TypeScript, or similar languages
• Experience building front-ends with React
• Experience with infrastructure (AWS/GCP/..), databases (Postgres, Valkey, Clickhouse), and modern CI/CD pipelines
• Bonus: UX/UI/design best practices. Familiarity with AWS, Temporal, LangChain, or financial/ERP integrations
• A builder’s mindset: you thrive in fast-moving environments and care about delivering quality fast
• Excitement about working at the intersection of AI, finance, and infrastructure
