Note: The job is a remote job and is open to candidates in USA. IR Labs is hiring a founding Principal Platform Engineer to build and operate the product platform and backend services that make its AI systems reliable, secure, and scalable. The role also establishes paved roads for engineering, productionizes AI workloads, and supports reliability, security, and operational practices.
Responsibilities
- Own the product platform, not just the infrastructure: build the core platform layer that turns our AI systems into a reliable, supportable product customers can onboard to and use daily
- Ship critical backend systems: design and implement core services/APIs that power signup/sign-in, tenancy, permissions, billing/entitlements, provisioning, and internal workflows so customer onboarding is seamless and repeatable
- Build “paved roads” that prevent engineering drag: create a standardized, self-serve path from feature → deploy → operate so teams can ship without repeated bespoke work, manual steps, or fragile runbooks
- Keep the AI critical path clean: absorb platform/ops/MLOps work that would otherwise pull our AI Scientist/MLE into toil and customer support, protecting our highest-leverage innovation hours
- Productionize AI workloads: build pragmatic MLOps and GPU operations foundations (serving/training workflows, model artifact distribution, utilization-aware scheduling, caching/cold-start strategies) so AI cost and latency remain controlled as we scale
- Create reliability as a system property: define SLIs/SLOs and error budgets, then enforce them through release standards, testing discipline, rollout patterns, and incident practices
- Embed security into the platform primitives: implement safe-by-default patterns for identity, access boundaries, secrets, and dependency hygiene so security is “how the platform works,” not a separate checklist
- Design for resilience with cost discipline: architect multi-region strategies (backup/restore, DR, failover) that are as simple as possible while meeting availability goals
- Make observability actionable: build high-signal metrics/logs/traces and operational dashboards that reduce noise and accelerate diagnosis; run blameless incident reviews that permanently reduce repeat failures
- Be a force multiplier across a senior team: partner closely with data infra, compiler, and AI leadership - review designs, unblock execution, and ship high-impact work directly when needed
Skills
- Principal-level “builder/operator” experience: you've built and run production systems end-to-end - design, implementation, deployment, on-call reality, and iteration under customer pressure
- Backend engineering strength: you can ship significant backend systems (APIs, workflows, auth boundaries, tenancy) and are comfortable owning core product services, not just infrastructure automation
- Strong systems coding: deep proficiency in Go and/or Rust (Python acceptable as supporting), plus solid shell skills; you can deliver large, correct changes quickly with tests and quality gates
- Kubernetes + cloud fluency: strong Kubernetes/EKS experience; you understand service networking, zero-downtime rollouts, autoscaling, and safe multi-tenant patterns. Comfortable with AWS primitives (VPC, IAM, EC2, S3, RDS) and multi-region architecture
- AI ops / GPU awareness: experience operating GPU-backed workloads or adjacent high-performance compute. You understand utilization, scheduling tradeoffs, and practical cost/performance management in production
- Reliability engineering mindset: you've used SLIs/SLOs/error budgets and know how to make reliability measurable and enforceable through engineering practice (not meetings)
- Security-by-design fundamentals: strong instincts and experience with identity/access patterns, secrets, dependency/supply-chain hygiene, and audit-friendly operational practices
- Automation-first execution: track record of eliminating operational toil through automation across CI/CD, provisioning, testing, and operations
- Customer-facing technical judgment: you can take customer feedback and translate it into platform capabilities that reduce friction, reduce support burden, and accelerate adoption
- Clear communication in ambiguity: you write crisp design docs, make tradeoffs explicit, and collaborate effectively across ML/data/backend in a fast-moving environment
