Senior Security Engineer

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're the kind of person who can't help but poke at systems, curious about how they work, how they break, and how they can be made stronger. At previous jobs, you were the one who opened up the hood, explored the edges, and asked:
"How could someone bypass this?"
and
"How do we fix it properly?"
You enjoy the craft of building secure systems just as much as understanding how to exploit them.

At Tandem, you'll bring that mindset to help us build a secure, fast, and reliable foundation for AI-powered healthcare tools used across Europe. You'll work hands-on across the stack: from application security and CI/CD pipelines to infrastructure hardening, penetration testing, and secure development practices. Your mission is simple but impactful: ensure Tandem can ship quickly and stay secure.

This is a role for someone who wants to be right in the middle of the action - designing secure architectures, breaking things safely, and helping developers stay productive without compromising safety. You will enable the business by proactively remove blockers. This is what makes us fast. You'll collaborate closely with the Head of Security, engineering teams, and compliance to build security into everything we do.

What You'll Do

• Work hands-on to secure Tandem's infrastructure, applications, and internal systems.
• Build and maintain secure-by-default practices across the software development lifecycle (SDLC).
• Implement and operate static and dynamic code analysis, dependency scanning, and secure CI/CD tooling.
• Conduct or lead penetration testing, threat modelling, and vulnerability assessments.
• Support secure architecture design across engineering, including container orchestration, IAM, networking, and secrets management.
• Help ensure Tandem can deliver code quickly while maintaining a strong security posture.
• Work closely with developers, pairing, reviewing, and advising to help them ship secure, high-quality code efficiently.
• Participate in incident detection, response, and security reviews.
• Collaborate with the Head of Security on long-term strategy, audits, and certifications (ISO 27001, MDR, GDPR).

What You Bring

• Strong hands-on experience in security engineering, application security, or infrastructure security.
• Experience with penetration testing, exploitation techniques, or red-teaming (formal or self-taught).
• Familiarity with secure CI/CD, code analysis tools (SAST/DAST), dependency scanning, and vulnerability management.
• Strong understanding of authentication, identity, secrets management, and secure networking fundamentals.
• Ability to collaborate deeply with developers and make security a natural part of engineering workflow.
• Pragmatic mindset - you know how to balance security and speed in a fast-moving environment.
• Curiosity, creativity, and a genuine interest in how systems work (and how they can break).

Bonus Points

• Experience with container orchestration (Kubernetes, ECS, Nomad)
• Hands-on experience with cloud infrastructure security (AWS/GCP/Azure)
• Experience contributing to ISO 27001 or SOC 2 audits
• Background in software development (Python, Go, TypeScript)
• Experience in threat modelling or vulnerability research
• Worked in a regulated or compliance-heavy environment (healthcare, fintech, govtech)
