Software Engineer - Internal Tooling

Tandem Health

BUILD SOMETHING MONUMENTAL FOR HEALTHCARE! At Tandem Health we’re reimagining healthcare by putting clinicians first. Our platform - designed by clinicians, for clinicians - is built on deep insight into real-world pain points, with intuitive medical notes and workflows that truly support patient care. We’re a fast-scaling health-tech company backed by top investors and expanding globally. We move fast, stay curious, and believe building something that matters starts with an extraordinary team. If you're passionate about impact and innovation, we'd love to meet you! ABOUT THE ROLE You care about making systems work where it really matters, behind the scenes, where complexity tends to hide. At your previous role, you were likely drawn to problems that others avoided: messy logic, unclear ownership, and workflows that didn’t quite hold together. You enjoy bringing structure to that - building systems that are not just functional, but reliable and easy to reason about. At Tandem, you’ll work at the intersection of product, operations, and business logic, owning and building the internal systems that power how we operate at scale. A key focus for this role is billing and invoicing, where product usage, access, and real-world workflows need to translate into correct, auditable invoices. This is not just about payments, it’s about deeply understanding how our product is used in practice, how that maps to our business model, and building the systems that make it all work seamlessly. You’ll work closely with engineering, operations, and commercial teams to ensure that what we build internally is robust, scalable, and aligned with how Tandem grows. If you enjoy working close to the business, taking ownership of complex logic, and building systems that directly impact how a company runs - this is your kind of role. WHAT YOU WILL DO * Own and build Tandem’s internal tooling and operational systems, with a primary focus on billing and invoicing. * Design and implement systems that connect product usage and access control to invoicing logic (e.g. integrations with Stripe). * Build workflows that ensure invoices are generated correctly based on real-world product behavior and customer setups. * Develop and maintain integrations between internal systems, databases, and external platforms (e.g. billing, CRM, analytics). * Work closely with operations and commercial teams to understand business needs and translate them into robust technical solutions. * Improve and automate internal processes to reduce manual work and increase reliability. * Build internal APIs and services that support operational workflows and scale with the company. * Take end-to-end ownership, from problem definition and system design to implementation, monitoring, and iteration. WHAT YOU BRING * Experience as a software engineer working on backend systems or internal tooling. * Strong ability to model and implement business logic in code, especially in complex or evolving domains. * Experience working with APIs, integrations, and data flows between systems. * Familiarity with cloud environments (e.g. AWS, Azure, or similar). * A pragmatic mindset - you focus on building systems that actually work in practice. * Interest in working close to the business and understanding how technical systems map to real-world operations. * Strong ownership and the ability to drive work independently in a fast-moving environment. BONUS POINTS * Experience working with billing, invoicing, or financial systems (e.g. Stripe or similar platforms). * Experience building internal tools or backoffice systems. * Familiarity with data modeling for usage-based systems. * Experience applying automation or AI to operational workflows * Experience in regulated environments (healthcare, fintech, etc.). LOCATION We believe the best ideas happen when we’re together. This role is based in our vibrant HQ in the Epicenter building in the heart of Stockholm where you will work primarily from our office to collaborate, connect, and build our culture. HOW TO APPLY We adopt a continuous selection process, so please make sure to apply with your CV in English. Our interview process consists of 4 stages: 1. Screening interview with Talent Acquisition 2. Technical interview with some of our Engineers 3. Interview with our CTO & Co-Founder 4. Home case and presentation at our office - Join us in the Stockholm office for a lunch, and a presentation to experience our our culture firsthand, collaborate with our team, and see how you work in action.

BENEFITS * Competitive salary & company stock options * 30 days/year of paid vacation * 5,000 SEK wellness allowance (friskvårdsbidrag) plus an additional 6,000 SEK yearly to spend on other health related initiatives * Generous Parental leave top-up for new parents * Private Medical Insurance to stay healthy * Mental health support through our partner Mindler * Pension program * Social and team-building activities (off-sites, after works, winter/summer parties) * An opportunity to make a real positive impact in the world of healthcare * Work with some of the best minds in AI, healthcare, and engineering.
