We are looking for a Site Reliability Engineer with up to 4 years of experience to own and build critical cloud infrastructure at an early-stage company working with cutting-edge aerospace, defense, and manufacturing customers. You'll be the first dedicated SRE on the team – designing, scaling, and automating systems with high agency and full end-to-end ownership. This is a greenfield opportunity to architect the path from AWS to on-prem deployments, support customer cloud environments, and improve observability across the platform. You should be a quick learner who thrives in restricted, regulated environments and is excited to make tough architectural decisions independently.
What you will be doing
Owning infrastructure end-to-end – designing, building, and scaling cloud and on-prem systems as the sole SRE
Architecting the migration path from AWS to on-prem and air-gapped environments for defense and federal customers
Deploying and supporting customer-specific cloud environments, ensuring the platform runs reliably across multiple tenants
Building observability and monitoring to improve signal from existing infrastructure and drive proactive reliability
Automating and improving current CI/CD pipelines, infrastructure-as-code practices, and deployment workflows
Dirac's BuildOS is the AI Process Design Platform, using AI + CAD to unify engineering and manufacturing, automatically telling a factory how to build a product. We drive factories to bring products to market faster, scale without headcount, and adapt instantly to change. Live across the industrial base, from defense-tech leaders to global industrial giants. In person, in the Empire State Building. We are an extremely high agency team and care deeply about our mission to Reindustrialize The West.

Dirac is a high-trust, high-agency environment where we do what we must to win. We give people real ownership and trust them to use their judgment, move quickly, and take responsibility for outcomes. We step up, solve the problem in front of us, and do what the moment demands. We challenge each other openly, adapt quickly, and hold a high bar for ourselves and the team. There’s a deep-rooted culture of people who genuinely care about the mission and each other.
BuildOS is Dirac's AI Process Design Platform — the first unified environment where manufacturing engineers author, version, review, and distribute the Build: the canonical definition of how a product gets produced.
Today, the work of defining how something gets built is scattered across process plans, MBOMs, routings, work instructions, spreadsheets, PLM configurations, ERP tables, and internal tools. Each artifact captures only a fragment of the process, forcing engineers to rebuild context every time a design changes. BuildOS brings all of these workflows together in one place.
The platform uses AI + CAD to unify engineering and manufacturing data, automatically telling a factory how to build a product. It transforms engineering data and tribal knowledge into standard, model-based production — replacing fractured legacy systems (ERP, PLM, MES) with a single source of truth. Think of it as: Figma owns the design file, GitHub owns the repo, Dirac owns the Build.
BuildOS enables factories to:
- Bring products to market faster by automating production planning — ECOs, assembly sequencing, work instructions, MBOMs, routings, and everything in between
- Scale without adding headcount by turning manual, spreadsheet-driven processes into automated workflows
- Adapt instantly to change by keeping every artifact in sync when a design revision lands
The platform spans a complex surface area — from 3D CAD interaction and structured data authoring to document generation and shop-floor workflows — and serves users ranging from highly technical manufacturing engineers to operators on the factory floor who may not have a college education. BuildOS is live across the industrial base, from defense-tech leaders to global industrial giants.
