Senior DevOps Engineer

Get to know us betterCodiLime is a software and network engineering industry expert and the first-choice service partner for top global networking hardware providers, software providers and telecoms. We create proofs-of-concept, help our clients build new products, nurture existing ones and provide services in production environments. Our clients include both tech startups and big players in various industries and geographic locations (US, Japan, Israel, Europe).While no longer a startup - we have 250+ people on board and have been operating since 2011 we’ve kept our people-oriented culture. Our values are simple:Act to deliver.Disrupt to grow.Team up to win.The project and the teamYou will join the team behind a leading network source-of-truth (NSoT) platform, used by thousands of organizations - from fast-growing tech companies to Fortune 500 enterprises - to model, document, and automate their network infrastructure.CodiLime engineers work within the platform's Observability team, which connects the network source of truth with what is actually running on the network. The team builds products for network discovery, network assurance (detecting drift between the intended and the actual state of the network), management of the agents that collect discovery and telemetry data, and a reliable pipeline that ingests this data into the platform.The platform is built AI-first, with its own Claude Code agent skills and MCP server, and that mindset carries over to how the team works: Claude Code is used heavily day to day to help the team move fast and consistently deliver high-quality results.In this role, you will build and run the infrastructure and tooling behind the platform's products - from AWS and Kubernetes environments, through CI/CD pipelines, to the observability stack - for both the SaaS and on-premise versions of the platform. The scale is significant: some of the platform's largest customers manage hundreds of thousands of devices across globally distributed environments.As the observability offering keeps growing, the team is looking for a Senior DevOps Engineer who manages infrastructure through code and automation, owns the reliability of what they deploy, and works closely with developers to get code to production.Technology stack:Cloud: AWS (EC2, VPC, IAM, RDS, EKS)Containerization & orchestration: Kubernetes (EKS), Docker, Docker ComposeInfrastructure as code: Terraform, HelmCI/CD: GitHub ActionsObservability: Prometheus, Grafana, Mimir, Loki, OpenTelemetryProgramming & scripting: Python, Go, shell scriptingData & messaging: PostgreSQL (RDS), event streaming and CDC, RabbitMQ, MQTTSecurity & compliance: IAM, SOC 2 controls, OAuth2APIs: REST, gRPCAI tooling: Claude Code, MCP servers, Anthropic toolingWhat else you should know:Small, cross-functional team with strong ownership of reliability, security and automationThe team is distributed across Europe and the US, and we are looking for someone whose working hours can overlap with the US East CoastAI tools are part of the daily workflow - Claude Code is used heavily across the teamThis is an infrastructure-focused role, working closely with the product teams to connect code to productionStartup-like vibe: proactive, ownership-driven, fast-pacedWe work on multiple interesting projects at a time, so it may happen that we’ll invite you to an interview for another project if we see that your competencies and profile are well suited for it.Your roleAs a part of the project team, you will be responsible for:Designing, building and maintaining infrastructure for both the SaaS and on-premise versions of the platformOperating and optimizing AWS infrastructure (EKS, EC2, VPC, IAM, RDS) for cost, security and performanceManaging infrastructure as code with Terraform and HelmBuilding and improving CI/CD pipelines in GitHub Actions and internal platform tooling that lets developers serve themselvesImproving monitoring, alerting and incident response, and defining SLOs (Prometheus, Grafana, Mimir, Loki)Helping enforce security and compliance standards, including SOC 2 controlsWorking closely with the product teams to get code to production reliablyContributing to documentation and onboarding, and taking part in the on-call rotationUsing Claude Code day to day: setting constraints, reviewing the output and staying accountable for correctness and securityDo we have a match?As a Senior DevOps Engineer, you must meet the following criteria:7+ years of experience in DevOps, SRE or platform engineeringStrong experience with AWS, especially EKS and KubernetesExperience with infrastructure as code using Terraform and HelmCI/CD experience (ideally GitHub Actions)Experience with observability tools such as Prometheus, Grafana, Mimir or Loki, and with OpenTelemetryProficiency in Python, Go or shell scriptingExperience with CDC and event streaming, or with scaling large multi-tenant observability systemsComfort in a fast-paced, ambiguous startup environmentHands-on, everyday use of AI coding tools (ideally Claude Code)Strong communication and documentation skillsAvailability for an on-call rotation and working hours overlapping with the US East CoastGood knowledge of English (minimum C1 level)Beyond the criteria above, we would appreciate the following nice-to-haves:Experience with SOC 2 or other security-focused environmentsExperience with messaging technologies such as MQTT or AMQP (e.g. RabbitMQ)Familiarity with network source-of-truth or network automation toolingOpen-source contributionsExperience working in a B2B software startup (ideally 2+ years)More reasons to join usFlexible working hours and approach to work: fully remotely, in the office or hybridProfessional growth supported by internal training sessions and a training budgetSolid onboarding with a hands-on approach to give you an easy startA great atmosphere among professionals who are passionate about their workThe ability to change the project you work on
