Tech Lead - Kubernetes-Native AI Platform

Join Our Team as a Tech Lead - Kubernetes-Native AI Platform

Are you a deeply hands-on technical leader with production-grade Kubernetes expertise and the ability to shape complex platform architecture under real enterprise constraints?

PortBlueSky is supporting a major multinational enterprise in scaling a widely adopted open-source, Kubernetes-native platform for agentic AI and enterprise automation. The platform is already used in demanding corporate environments and now needs stronger product stability, clearer technical direction, and a more mature architecture for production-scale adoption.

We are looking for a Tech Lead who can relieve the current lead, take ownership of core product direction, and raise the engineering bar across architecture, APIs, reconcilers, deployment patterns, and developer experience.

Role and Responsibilities

As Tech Lead, you will:

  • Drive technical direction and product stability: Shape the architecture, roadmap, and engineering standards for a Kubernetes-native AI platform used in complex enterprise environments.

  • Lead core Kubernetes API design: Review and improve CRDs, controllers, admission/defaulting behavior, API versioning, RBAC, status semantics, generated SDK impact, and long-term API compatibility.

  • Strengthen reconciliation and orchestration patterns: Guide reconciler design, agentic loop scheduling, finalizers, async execution, cancellation, retries, ownership models, failure recovery, and safe state transitions.

  • Maintain a declarative workflow mindset: Apply an Argo-like mental model for workflow placement, workload orchestration, resource reconciliation, and operational state management.

  • Work hands-on on critical paths: Contribute directly in Go and Kubernetes code when core runtime, API server, provider abstraction, storage, auth, or deployment work needs unblocking.

  • Keep the wider system coherent: Reason across the runtime, aggregated API server, Postgres-backed storage mode, completions executor, MCP/A2A flows, Helm deployment model, API service, SDKs, CLI, broker, and dashboard.

  • Enforce strong review standards: Set high expectations for CRDs, reconcilers, API server behavior, auth flows, production defaults, provider abstractions, tests, and backward compatibility.

  • Prepare the platform for enterprise reality: Anticipate what breaks in real clusters, including identity, network policy, custom CAs, proxies, multi-tenancy, observability, storage, upgrades, and HA.

  • Improve open-source usability: Champion five-minute onboarding, clean documentation, useful examples, high-quality release notes, community demos, GitHub hygiene, and contributor friendliness.

What We Offer

  • A technically ambitious project: Work on a production-grade, open-source platform at the intersection of Kubernetes, agentic AI, workflow orchestration, and enterprise automation.

  • A senior engineering environment: Collaborate with highly experienced developers, tech leads, architects, and DevOps experts who care deeply about quality and communication. PortBlueSky’s public positioning emphasizes handpicked experts, senior-level delivery, and strong communication in enterprise environments.

  • Remote-first flexibility: Work from where you are most productive, with flexible working conditions and a family-friendly setup.

  • Meaningful technical ownership: Influence architecture, product direction, developer experience, and production-readiness instead of simply executing tickets.

  • Open-source relevance: Contribute to a platform that matters beyond one client environment and has a real developer ecosystem.

About You

You are a senior technical leader with:

  • Deep, production-grade Kubernetes expertise, including CRDs, controllers, admission/defaulting, API versioning, RBAC, status semantics, and API compatibility.

  • Strong experience with reconciler architecture, failure recovery, async execution, cancellation, retries, finalizers, ownership semantics, and status transitions.

  • Strong Go fluency and enough Python, Node.js, and TypeScript literacy to keep service, SDK, CLI, broker, and dashboard decisions aligned.

  • Experience reviewing Kubernetes-native APIs for idiomatic shape, operational safety, compatibility, and developer usability.

  • A production-hardening mindset shaped by real enterprise clusters, not only local demos.

  • Excellent communication skills and the ability to set direction while remaining hands-on.

  • Fluent English and the ability to collaborate effectively in an international, remote-first environment.

  • EU residency and permission to work in the EU.

Nice to Have

  • Experience with aggregated API servers, Kubernetes API machinery, Postgres-backed resource storage, OpenAPI generation, or SDK generation.

  • Familiarity with MCP, A2A, agentic workflow systems, model gateways, or AI orchestration platforms.

  • Experience maintaining open-source projects, reviewing community contributions, writing technical documentation, or preparing release notes.

  • Prior work in enterprise consulting, forward-deployed engineering, or high-stakes platform modernization.
