This is a hands-on infrastructure engineering role: you will design and operate production Kubernetes platforms, build and extend infrastructure capabilities using Crossplane, and develop services, controllers, and platform tooling that other engineering teams depend on.\nThe work spans Kubernetes platform architecture, infrastructure orchestration, networking, observability, and production operations. You will work with Kubernetes APIs, Crossplane, Terraform, GitOps, and production software development to build reusable, self-service infrastructure capabilities. We are looking for someone comfortable owning ambiguous, multi-quarter initiatives and driving them independently from design through production.\nKey Responsibilities:\nPlatform and Kubernetes Engineering:\nDesign, build, and operate production Kubernetes clusters, including cluster networking, workload isolation, and multi-region topologies.\n\nBuild and extend infrastructure orchestration capabilities using Crossplane, Kubernetes custom resources, controllers, and operators.\n\nWork with Kubernetes internals: resource quota management, scheduling and cluster behavior, NetworkPolicy enforcement, and reconciliation patterns.\n\nDevelop reusable, self-service platform capabilities that enable engineering teams to provision and manage infrastructure consistently.\n\nImplement and operate service mesh capabilities: mTLS between services, service-account-level authentication and authorization, and traffic management across internal and external request paths.\n\nOptimize containerized workloads for performance, cost, resource efficiency, and blast-radius reduction.\n\nSoftware Development in Go, Python, or Java:\nWrite, refactor, and maintain production services, Kubernetes controllers, operators, and platform middleware, preferably in Go.\n\nWork with Kubernetes APIs, custom resources, reconciliation loops, and Go-templated YAML to extend infrastructure capabilities.\n\nRead and contribute to complex existing codebases, including open-source projects that we customize or extend.\n\nBuild HTTP, REST, and gRPC service interfaces used by internal engineering teams.\n\nWrite meaningful unit and integration tests, and treat testability as a design property rather than an afterthought.\n\nReliability and Production Operations:\nLead incident response for platform-level issues; investigate root causes and implement durable fixes.\n\nTroubleshoot production Kubernetes infrastructure and distributed systems using logs, metrics, traces, and profiling tools.\n\nDesign resilient infrastructure with appropriate workload isolation, failure-domain boundaries, and blast-radius reduction.\n\nDiagnose and resolve performance, capacity, and reliability problems across distributed systems and data-intensive workloads.\n\nDefine and drive SLOs, and build the alerting that makes them actionable.\n\nInfrastructure as Code and Delivery:\nDesign, build, and maintain reusable Terraform modules and Crossplane infrastructure abstractions consumed by other engineering teams.\n\nDevelop and evolve infrastructure provisioning and orchestration workflows using Crossplane, Terraform, and GitOps.\n\nBuild and improve CI/CD and GitOps delivery workflows so that teams can ship safely and frequently.\n\nBalance developer velocity against reliability, security, and compliance requirements.\n\nSupport cloud migration initiatives, including moving production infrastructure between cloud providers or environments while maintaining reliability and minimizing downtime.\n\nObservability:\nBuild and maintain metrics, dashboards, alerting policies, and distributed tracing.\n\nInstrument platform components and infrastructure services so that failures are diagnosable without a code change.\n\nCollaboration:\nPartner with data engineering, product, security, and infrastructure teams to gather requirements and align on architecture.\n\nContribute to design reviews and help set technical direction for the data platform.\n\nMentor other engineers and raise the standard of platform engineering practices.\n\nIndependently drive complex infrastructure initiatives, communicating technical decisions, trade-offs, and progress to stakeholders.\n\nQualifications:\nEducation and Experience:\n7+ years of professional experience in software, platform, infrastructure, or site reliability engineering, including significant experience operating production distributed systems.\n\nDemonstrated experience building and operating production Kubernetes platforms, not only deploying applications onto them.\n\nProduction software development experience in Go, Python, or Java, with Go strongly preferred.\n\nExperience building infrastructure or internal developer platforms consumed by multiple engineering teams.\n\nExperience designing, developing, and maintaining reusable Terraform modules or equivalent infrastructure abstractions.\n\nExperience independently designing systems from an ambiguous starting point and carrying them through implementation and production.\n\nDegree in Computer Science, Engineering, or a related field, or equivalent practical experience.\n\nTechnical Skills:\nStrong understanding of Kubernetes internals: networking (CNI), NetworkPolicy, resource management, scheduling, cluster lifecycle, and behavior under load.\n\nHands-on experience with Kubernetes APIs, custom resources, controllers/operators, and reconciliation patterns.\n\nStrong production coding experience building and maintaining services or platform tooling, preferably in Go.\n\nExperience with declarative infrastructure orchestration and provisioning; Crossplane experience is highly preferred.\n\nInfrastructure as Code at scale, particularly Terraform module design and ownership.\n\nStrong understanding of GitOps practices, preferably with Argo CD.\n\nHands-on experience with a service mesh (Istio, Envoy, Linkerd, or similar), including mTLS and workload identity.\n\nSolid Linux fundamentals, including cgroups, networking, and resource management.\n\nProduction experience with at least one major cloud platform (GCP, AWS, or Azure); multi-cloud experience is a strong plus.\n\nObservability tooling: Prometheus, Grafana, OpenTelemetry, and query languages such as PromQL.\n\nProduction experience with relational databases, including PostgreSQL or managed Postgres-compatible services, and an understanding of replication and failover characteristics.\n\nDocker and container tooling as part of the delivery lifecycle.\n\nStrong debugging and performance profiling skills.\n\nPreferred:\nHands-on Crossplane experience, including Compositions, XRDs, providers, managed resources, or custom infrastructure abstractions.\n\nOpen-source contributions to CNCF or Kubernetes ecosystem projects such as Crossplane, KEDA, Argo CD, Strimzi, or Envoy.\n\nExperience with large-scale data platforms and technologies such as Apache Kafka, Apache Flink, or Apache Spark.\n\nExperience with Alibaba Cloud (AliCloud), particularly production infrastructure or cloud migrations.\n\nExperience designing resilient distributed systems using cell-based architectures, workload isolation, and blast-radius reduction.\n\nKubernetes certifications such as CKA, CKAD, or KCNA.\n\nExperience with Go testing frameworks such as Ginkgo and Gomega.\n\nAdditional strength in Python.\n\nExperience with identity and access management: SSO, Keycloak, OIDC, SAML, or secret management with Vault or a cloud equivalent.\n\nExperience designing for high availability and disaster recovery across regions or providers.\n\nExperience working in a monorepo and with build systems such as Bazel.\n\nAbility to read Java.\n\nExposure to compliance frameworks such as SOC 2 or GDPR.\n\nParticipation in the Kubernetes/CNCF community, including KubeCon attendance, speaking, or open-source contributions.\n\nSoft Skills:\nStrong analytical and problem-solving ability.\n\nClear written and verbal communication, particularly in design documents, technical trade-offs, and cross-team requirements gathering.\n\nHighly autonomous and proactive, with the ability to identify infrastructure gaps, propose solutions, and drive implementation.\n\nAble to independently own complex platform engineering initiatives from design through production.\n\nComfortable in a fast-moving, highly technical environment.\n\nPlease Note:\nThis is a hands-on Kubernetes platform engineering role focused on infrastructure orchestration for a large-scale data platform. We are not looking for candidates whose experience is primarily CI/CD, application deployment, cloud architecture, or consuming managed Kubernetes services.\nThe ideal candidate has built and operated production Kubernetes infrastructure, developed reusable platform capabilities consumed by other engineering teams, and has strong production software engineering experience. Experience with Crossplane and Go is particularly valuable, alongside the ability to independently own complex infrastructure problems and explain the architecture, implementation, and operational trade-offs behind the systems they build.","description_format":"text","description_chars":9277,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Brazil","iso":"BR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Cost & Multi-Cloud Management","Cloud Consulting & Migration"],"lifecycle":[{"event":"open","at":"2026-11-13T11:39:39Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":64,"reasons":["conf:4","velocity","win:early"],"computed_at":"2026-11-14T05:58:10Z"},"pay":null,"html_url":"https://alion.io/job/virta-sant-senior-platform-engineer-crossplane","json_url":"https://alion.io/job/virta-sant-senior-platform-engineer-crossplane.json","meta":{"generated_at":"2026-11-14T15:43:39Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":17508,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2124108},"rest":"https://alion.io/mcp/rest/get_company?id=2124108"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvirta-sant-senior-platform-engineer-crossplane"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fvirta-sant-senior-platform-engineer-crossplane"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fvirta-sant-senior-platform-engineer-crossplane"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/virta-sant-senior-platform-engineer-crossplane\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvirta-sant-senior-platform-engineer-crossplane"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4234788}},{"tool":"search_jobs","arguments":{"company":"virtasant.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4234788},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
