Dive in and do the best work of your career at DigitalOcean. Journey alongside a strong community of top talent who are relentless in their drive to build the simplest scalable cloud. If you have a growth mindset, naturally like to think big and bold, and are energized by the fast-paced environment of a true industry disruptor, you’ll find your place here. We value winning together—while learning, having fun, and making a profound difference for the dreamers and builders in the world. We are seeking a Senior Software Engineer (IC3) to join our Security Products team working on Key Management Systems (KMS).

What You'll Do Own Technical Workstreams: Design and build high-availability, security-critical key management services in Go , taking end-to-end ownership from design through production operation. Drive Key Lifecycle Engineering: Lead the design and implementation of key generation, rotation, escrow, and destruction workflows — owning the design decisions, correctness guarantees, and audit trail requirements, not just the implementation. Advance Envelope Encryption: Design and scale the DEK/KEK hierarchy that protects customer data at rest ac
