About the role

You won't pull pre-scoped tickets from a backlog.
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.

Holokai is looking for a backend engineer to build core product alongside their co-founders and senior engineering team.
You'll work with their senior engineers and leadership to decide what to build, then build it well.
They're heavy AI users in how they build, not just in what they ship.
Write simple code, ship often, and own what you put in production.
Engineering, product, sales, and customer success all own success together.

LLM APIs and AI/ML pipelines: prompt engineering, model integration, token economics
Policy engines or rules-based systems (OPA/Rego, decision engines, or similar)
Message queues and event-driven architectures (RabbitMQ, SQS, Kafka)
Frontend chops (React)
not the focus, but handy for closing the loop on a feature
Enterprise security, compliance, or governance experience (e.g. SOC 2, GDPR, etc.)
Who thrives here:
At a start-up our size and stage, there's no living in a silo.

Strong production experience in TypeScript and Go (Python a plus): real services running in production, not scripts and notebooks
Relational databases, PostgreSQL: schema design, query performance, migrations
Reading and extending code you didn't write, quickly and confidently
Fluent with AI-assisted development tools (Claude Code, Cursor, or similar); you use them daily and they make you meaningfully faster
Production experience with AWS
Containerized deployments (Docker, ECS, EKS, or similar)
Self-directed and comfortable with minimal structure in a fast-moving start-up environment
U.S. Citizenship required
Bachelor's in Computer Science, Engineering, or a related field, or equivalent professional experience.

They need engineers who have built and owned critical production running at real scale to serve exacting enterprise customers.
They are an early-stage startup with pilot customers, rapid product iteration, and direct customer feedback loops.
