Senior Engineer, Backend

hatch I.T. is partnering with Holokai to find a Senior Backend Engineer. See details below: About the Role:  Holokai is looking for a backend engineer to build core product alongside their co-founders and senior engineering team. You won’t pull pre-scoped tickets from a backlog. You’ll work with their senior engineers and leadership to decide what to build, then build it well. The Holokai platform spans a user desktop application, policy enforcement engine, an agentic workflow orchestrator, a model-agnostic gateway, and a SaaS management console. You’ll work across all of it, primarily in TypeScript and Go with some Python. The hard parts are genuinely hard, including sub-100ms policy evaluation, multi-model orchestration, and enterprise-grade security. They want someone who stays clear-headed in that complexity. They need engineers who have built and owned critical production running at real scale to serve exacting enterprise customers. That experience leaves a mark: the battle scars that keep you from over-engineering at the expense of reliability and pragmatism. They're heavy AI users in how they build, not just in what they ship. AI-assisted development is core to how this team works; they want someone who puts AI to work but catches it when it’s about to steer them wrong. Write simple code, ship often, and own what you put in production.   About Holokai: Holokai is building a platform to accelerate the secure, rational adoption of Enterprise AI. Their product enables organizations to safely deploy AI tools through model access controls, governance guards, and policy enforcement — while still delivering strong user productivity through a desktop chat experience and integrated AI workflows. They are an early-stage startup with pilot customers, rapid product iteration, and direct customer feedback loops. Designers at Holokai work close to product decisions and engineering implementation, not as a downstream function but as a core part of product creation.
