Job description

Location: Austria, Germany, UK or Finland Contract type: Full-time, permanent

Who are we?

Springtime Technologies helps finance teams turn accounts payable from a manual cost centre into a source of real-time financial intelligence. Invoicetrack puts every invoice on a single platform, uses AI trained on each customer's own invoice history to resolve the exceptions that broke every earlier tool, and shows finance leaders exactly where to act first.

Founded in 2004 by AI pioneers and headquartered in Austria, we are a fast-growing team of finance and technology specialists, with teams in Germany, the UK, Finland and the Philippines. Our technology serves 200,000+ users in 75+ countries, and we measure ourselves by customer outcomes.

The Role.

Build the function. Own the story.

We are growing our Automation engineering team and we are on the look out for senior engineers. The team builds the services behind Invoicetrack's automation and data capabilities, working closely with product management on a clear goal: fewer human touchpoints for every invoice.

You are a senior engineer with real ownership. You design, build and run what you ship, and you help shape how the team works. One of these roles carries stronger technical leadership: setting standards, guiding design decisions and raising the quality of the whole team.

If that is you, tell us.

What will you do?

Build the automation finance teams rely on.

• Design and build Python services. Own back-end services and RESTful APIs from design to production, with clean, tested and maintainable code and clear API contracts for everything that consumes them.
• Shape the architecture. Lead back-end architecture and data modelling decisions, applying clean architecture, domain-driven design and proper separation of concerns so the platform stays scalable, fast and maintainable.
• Put AI to work. Integrate LLM APIs and AI/ML components into production services, and approach every design with one question: what can a model automate, enrich or replace?
• Set the quality bar. Establish coding standards and best practices through code review, design discussion and example, and give feedback that helps other engineers improve.
• Work with product. Turn product problems into technical solutions with the product manager, and push back when there is a simpler or better way.
• Run what you build. Ship through CI/CD pipelines, building application images with Docker and deploying them to Kubernetes, then monitor, troubleshoot and improve services in production for enterprise customers.
• Grow the team. Share knowledge, support other engineers and help hire the people who join after you.

What will you bring?

A senior engineer who makes a difference.

• Senior Python experience. 5+ years of professional experience building production Python systems, with strong fundamentals in software design, testing and performance.
• An AI-first way of working. You use AI tools such as GitHub Copilot and Claude as your default in daily development, not occasionally. You have hands‑on experience integrating LLM APIs (OpenAI, Anthropic Claude, Azure OpenAI) or AI/ML components into production applications.
• APIs, systems and data. Strong experience designing RESTful APIs and distributed systems, and building on relational databases such as PostgreSQL and MS SQL Server.
• CI/CD and containers. A working understanding of CI/CD pipelines, building container images with Docker and running services on Kubernetes.
• Collaboration. You work well with engineers and product managers, and you make the people around you better.
• Ambition and drive. You want to make a difference, take ownership and hold yourself to a high standard.
• Technical leadership. A track record of setting standards or leading technical decisions is a strong plus, and essential for one of the two roles.
• SaaS experience. Experience with SaaS platforms is a plus, though not required.
• Front-end experience. Experience building production UIs with React and TypeScript, including state management, component architecture and front-end performance, is a strong plus.
• Clear communication. Excellent English, written and spoken.

What will you get?

Work with brands the world knows Our customers include some of the best-known names globally. Your work reaches them.

Flexible working Flexibility in how and where you work, so you can do your best work.

Engineering that matters Your work runs in the AP processes of enterprises worldwide, every day.

At the centre of the AI momentum Springtime is AI native, and you are in a core role in taking it to market: you shape the story, design the approach and launch it.

Our process: a screening call followed by technical interviews with the engineers and engineering leads you would work with. Final round is an onsite interview with the team.

The minimum gross salary for this position is €4,611 per month, as determined by the IT Collective Agreement. The actual salary will be based on your qualifications and experience.
