Remote (UK-based) | Help Shape the Future of Veterinary Care

IVC Evidensia is on a mission to set the global standard for veterinary care—and we need exceptional engineers to make that happen.

With 2,500+ clinics in over 20 countries and a growing community of 41,000+ professionals, we’re building a best-in-class tech team that’s grounded in purpose and driven by innovation.

? Your Role in Our Vision

As a Principal Software Engineer, you’ll be a key technical leader—shaping architecture, mentoring teams, and driving large-scale engineering initiatives. You'll work across multiple product teams to create scalable, secure, and meaningful systems that support veterinary professionals and pet owners worldwide.

? What You’ll Do

• Set technical direction and provide architectural guidance across multiple teams.
• Champion best practices: cloud-native design, DevOps, CI/CD, observability, TDD, and Pair Programming.
• Collaborate with product, data, UX, and platform teams to build scalable, event-driven systems.
• Mentor and grow senior engineers, promoting a high-performance, inclusive culture.
• Lead delivery of impactful cross-team technical initiatives.

? What You Bring

• Deep expertise in .NET/C#, AWS, microservices, and distributed systems.
• Strong leadership and mentoring skills.
• Proficiency with messaging systems (SNS/SQS, Kafka), CI/CD, and container orchestration (EKS/Kubernetes).
• Passion for craftsmanship and engineering excellence.

Bonus if you have experience in healthcare/clinical systems, semantic search, or front-end technologies like React/Next.js.

? What We Offer

• Remote-first culture with access to offices in London and Bristol.
• 5 weeks' vacation + bank holidays, private healthcare, EAP, and more.
• A team that values collaboration, innovation, and psychological safety.
