By combining open source innovation with deep expertise in Kubernetes orchestration, Mirantis empowers platform engineering teams to deliver composable, production-ready developer platforms across any environment-on-premises, in the cloud, at the edge, or in sovereign data centers. As enterprises navigate the growing complexity of AI-driven workloads, Mirantis delivers the automation, GPU orchestration, and policy-driven control needed to manage infrastructure with confidence and agility. Committed to open standards and freedom from lock-in, Mirantis ensures that customers retain full control of their infrastructure strategy. https://www.mirantis.com/\n Job Summary:\nWe are looking for a backend engineer to build the Go services behind the k0rdent-ai platform - the multi-tenant control plane for enterprise GPU infrastructure. As AI workloads scale globally, you will collaborate with engineering teams across the US, Europe, and India to design and develop the API-first services that power this ecosystem.\nYou will own features end to end - API contract, service, schema, orchestration, tests, and packaging - with senior engineers alongside you for design review and support. We do not expect you to arrive knowing our whole stack; we expect strong Go and API fundamentals, and the appetite to learn the rest quickly. Working within an agile framework, you will directly impact the reliability and correctness of the infrastructure our customers run in production.\nMain Responsibilities:\nBuild Go microservices, model database schemas, and write migrations for the multi-tenant k0rdent AI platform.\n\nDesign public REST APIs with OpenAPI, along with multi-language SDKs.\n\nImplement durable orchestration in Temporal - idempotency, retries, timeouts, determinism constraints.\n\nBuild event-driven, asynchronous communication between services on a distributed streaming or message-broker platform.\n\nImplement authentication and authorization boundaries across an enterprise IAM platform and an API gateway - OIDC/JWT, service-to-service auth, tenant-scoped RBAC, gateway routing, and rate limiting.\n\nContribute to the identity model - standards-based user and group lifecycle provisioning (SCIM), and unifying authorization between the platform's API permissions and Kubernetes-native RBAC.\n\nWrite unit, integration, and end-to-end tests as part of every change.\n\nInstrument services for production - structured logging, metrics, and audit trails.\n\nPackage and ship services with Docker, Helm, and Kubernetes.\n\nReview peers' code and debug incidents to root cause with regression coverage.\n\nRequired Skills/Abilities:\nBachelor's degree in Computer Science, Software Engineering, or a related field - or equivalent demonstrated ability.\n\nSolid CS fundamentals: data structures, algorithms, concurrency, networking, and how HTTP and databases actually work.\n\n4-5 years of professional software engineering, including 2-3+ years building production backend services in Go (4+ years of Go preferred).\n\nStrong Go fundamentals: concurrency, context propagation, error wrapping, stdlib HTTP routing (Go 1.22+).\n\nExperience building and shipping REST APIs, and a working understanding of versioning and backward compatibility.\n\nSolid relational database skills - schema design, migrations, transactions, and query tuning.\n\nTesting discipline: unit and integration tests are part of your definition of done, alongside code review and CI/CD (GitHub Actions or equivalent).\n\nClear written English for design docs, review comments, and asynchronous collaboration across global time zones.\n\nAuthorization to work in the United States.\n\nTech Stack (Prior Experience Preferred, Not Mandatory)\nCandidates with strong Go and API design basics are evaluated primarily; prior familiarity with these tools is beneficial, though on-the-job mastery is anticipated.\nDurable Workflow Execution: Temporal orchestrations.\n\nCloud-Native & Kubernetes Ecosystem: Container orchestration using Kubernetes, Cluster API, custom controllers and operators, Docker runtime, and deployment packaging through Helm charts.\n\nIdentity Federation & Ingress Gateway: Keycloak architecture (realms, client configurations, federated providers, auth token lifecycles) alongside Envoy or comparable edge proxies (traffic management, filter chains, rate limiting policies).\n\nPersistence & Event Infrastructure: Relational data persistence in PostgreSQL with database schema migration workflows, coupled with distributed streaming platforms like Apache Kafka or NATS JetStream messaging.\n\nMust Have\nThe \"I'll figure it out\" instinct - you research, experiment, and read source code before asking to be unblocked, and you ask a well-formed question when you are.\n\nSomething you built and can walk us through in detail: what it does, why you designed it that way, and what you would change now.\n\nWillingness to be reviewed rigorously and to treat feedback as the fastest way to get better.\n\nTesting instinct - you can explain how you know your own code works.\n\nAuthorization to work in the United States.\n\nNice to Have\nMulti-tenant SaaS or PaaS platform experience.\n\nk0s ecosystem experience.\n\nExposure to GPU infrastructure or AI/ML workload scheduling on Kubernetes.\n\nSCIM provisioning, or federating platform permissions with Kubernetes RBAC.\n\nsqlc, OpenAPI codegen, or other schema-driven toolchains.\n\nObservability: Prometheus, Grafana, OpenTelemetry, audit logging.\n\nPython or TypeScript for E2E suites and client SDKs.\n\nSecurity engineering: threat modeling, secret management, dependency and container scanning.\n\nCNCF open-source contributions.\n\nWhat does Mirantis offer you?\nWork with an established Silicon Valley leader in the cloud infrastructure industry;\nWork with exceptionally passionate, talented and engaging colleagues, helping Fortune 500 and Global 2000 customers implement next-generation cloud technologies;\nBe a part of cutting-edge, open-source innovation;\nThrive in the high-energy environment of a young company where openness, collaboration, risk-taking, and continuous growth are valued;\nProfessional development and training;\nAttend conferences and working groups;\nCompany outings, happy hours, hackathons, and tech talks;\nReceive a competitive compensation package with a strong benefits plan.\nWe are a Leader for Container Management in G2 (#2 after AWS)!","description_format":"text","description_chars":6563,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All
