Senior /staff software Engineer Infrastructure

The opportunity

Work directly with the founding team as one of the first dedicated infrastructure engineers on a

team of approximately seven. Take ownership of infrastructure currently managed by the

co-founder and help scale reliable systems for hundreds of thousands of applications, while

maintaining an excellent developer experience.

What you will do

- Own infrastructure reliability, uptime, scaling and on-call responsibilities.

- Design and evolve systems for long-running AI agents, durable workflows and multi-tenant

application hosting.

- Build and operate workflow orchestration using Temporal or a comparable production system;

design robust recovery for partial failures.

- Manage cloud infrastructure as code using CDK or Terraform, and orchestrate fleets of servers or

containers.

- Design, scale and tune production databases; the platform uses Postgres, Redis and ClickHouse.

- Partner with the founders to drive ambiguous technical goals through architecture,

implementation, production launch and ongoing improvement.

- Use AI AI coding tools daily to accelerate delivery while maintaining a high bar for technical quality.

Mandatory requirements / deal breakers

- End-to-end ownership: Has owned and shipped an entire product module, such as

authentication/access management, CMS, email, files or billing; experience must extend beyond

small features and bug fixes.

- Production workflow orchestration: Hands-on experience with Temporal or a comparable

durable workflow orchestrator, such as Cadence or AWS Step Functions.

- Infrastructure as code and fleet operations: Manages infrastructure in CDK or Terraform

and has orchestrated servers or containers, for example Kubernetes or Docker on AWS.

Required background

- Typically 2 - 10 years of experience in infrastructure, platform or backend engineering, with

senior or staff-level ownership and technical depth.

- At least 1 year at a fast-growing startup with fewer than approximately 150 employees, ideally

pre-Series C, or at a high-bar developer tools or product company. Founder and YC startup

experience count.

- Deep production database experience spanning schema design, scaling and performance

tuning.

- Daily use of AI coding tools, with the ability to explain a practical workflow using tools such as

Claude Code, Cursor or background agents.

- A clear record of shipping, strong autonomy, urgency, excellent communication and increasing

scope of responsibility. Evidence may include launches, meaningful GitHub contributions,

open-source work or technical writing.

Nice to have

- Infrastructure for AI agents or ML workloads, including long-running jobs, model routing,

inference or GPU orchestration.

- Experience with Kubernetes, AWS and the Hercules stack: TypeScript, React and Postgres.
