Senior Platform Engineer (Learn)

About Sana

Sana is an AI lab building superintelligence for work.

We believe organizations can accomplish their missions faster when humans can effortlessly access knowledge, automate repetitive work, and learn anything with the help of agentic AI.

As part of Workday, we are committed to building AI that augments humans.

If that’s a mission that excites you, you’re in the right place.

About the role

You’ll own the reliability, security, and scalability of Sana’s platform while leveling up developer velocity. This is the place for engineers who thrive on moving between cloud infrastructure, deployment, and tooling to unblock everyone else. You’ll work on everything from multi-tenant scale-out to developer experience, ensuring our platform is robust, secure, and a joy to build on.

In this role, you will

• Drive reliability, security, and scalability across the platform

• Architect and implement multi-tenant scale-out (10–100x) and observability solutions

• Lead incident response, performance profiling, and cost control initiatives

• Build and maintain CI/CD pipelines, test infrastructure, and environment provisioning

• Work with engineers across the stack to remove friction and accelerate delivery

What success looks like

• The platform scales seamlessly as usage grows 10-100x, with robust observability and incident response

• Security and compliance are built-in, not bolted on

• Developer velocity is tangibly higher—teams ship faster, with fewer blockers

• CI/CD, test infra, and development environments are reliable, discoverable, and loved by engineers

• Cost controls and performance budgets are visible and actionable

• You are a go-to partner for infra, deployment, and tooling challenges: unblocking others and raising the bar for engineering excellence
