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).\nWhile 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:\nAct to deliver.\n\nDisrupt to grow.\n\nTeam up to win.\n\nThe project and the team\nYou 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.\nCodiLime engineers work within the platform's Observability team, which builds the software responsible for network discovery and reconciliation (keeping the platform's documented network state in sync with what is actually discovered on the network), network observability and monitoring, as well as the agents and fleet management that collect data from customer networks. The team develops both closed-source and open-source components, used by the product's large community. Observability is a key part of network automation: it keeps the platform's view of the network accurate and up to date.\nThe 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: AI-assisted development is actively cultivated day to day to help the team move fast and consistently land high-quality results.\nThe scale is significant - some of the platform's largest customers manage hundreds of thousands of devices, each with multiple interfaces, across globally distributed environments.\nAs the observability offering keeps growing, the team is looking for a Senior Software Engineer who can strengthen coverage in US time zones.\nTechnology stack:\nProgramming languages: Go (primary language), Python (tests and tooling)\n\nAPIs: gRPC, Connect RPC, with Protobuf\n\nData & messaging: PostgreSQL (including migrations), Redis, RabbitMQ\n\nArchitecture: multi-tenant services, event-driven systems\n\nSecurity: OAuth2 / OIDC\n\nObservability: OpenTelemetry, metrics and instrumentation, Grafana, Prometheus\n\nNetwork & device protocols: SNMP, gNMI, CLI-based collection, MQTT\n\nContainerization & Orchestration: Docker (Docker Compose for local/test environments), Kubernetes\n\nCloud: AWS\n\nCI/CD: GitHub Actions, Ansible\n\nAI tooling: Claude Code, MCP servers, Anthropic tooling\n\nWhat else you should know:\nSmall, cross-functional team with strong ownership of code quality, security and tests\n\nThe team is distributed across Europe and the US, and we are looking for someone to strengthen coverage in US time zones (ideally Eastern Time), including customer support, production issues and on-call\n\nAI tools are part of the daily workflow, including AI-assisted test writing and internal data/feed management tooling\n\nThis is a backend-focused role\n\nStartup-like vibe: proactive, ownership-driven, fast-paced\n\nWe 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.\nYour role\nAs a part of the project team, you will be responsible for:\nDesigning and building Go services for network discovery and reconciliation, network observability and monitoring, and agents and fleet management\n\nDesigning multi-tenant ingestion pipelines for network device data, with clear delivery guarantees, idempotency and predictable behavior under load\n\nCollecting device identity and state from network devices using protocols such as SNMP, gNMI and CLI\n\nBuilding and evolving gRPC and Connect RPC APIs defined in Protobuf, and working with PostgreSQL, Redis and RabbitMQ\n\nInstrumenting services with OpenTelemetry and keeping metrics clean and meaningful\n\nExploring and applying AI-assisted engineering practices - such as interactive, Claude Code-driven testing flows - to make development and testing faster and more reliable\n\nWriting technical specifications with diagrams and contributing to architecture and design decisions\n\nSupporting customers, production issues and on-call in US time zones\n\nWriting clean, maintainable, well-tested code and participating in code reviews\n\nDo we have a match?\nAs a Senior Software Engineer, you must meet the following criteria:\n5+ years of professional software engineering experience\n\nStrong professional experience with Go\n\nExperience with gRPC and/or Connect RPC APIs defined in Protobuf\n\nExperience with PostgreSQL (including migrations), Redis and RabbitMQ\n\nExperience with multi-tenant services and OAuth2 / OIDC\n\nDeep knowledge of observability and instrumentation, including OpenTelemetry\n\nFluency and experience with Docker, Docker Compose\n\nExperience with Kubernetes\n\nExperience with event-driven systems, including at-least-once delivery and idempotent consumers\n\nSolid understanding of networking: devices, configuration, protocols and layers\n\nCI/CD experience (ideally GitHub Actions)\n\nHands-on, everyday use of AI coding tools (ideally Claude Code)\n\nAvailability to work in US time zones (ideally Eastern Time)\n\nGood knowledge of English (minimum C1 level)\n\nBeyond the criteria above, we would appreciate the following nice-to-haves:\nExperience with MQTT or other device/IoT protocols, or gNMI\n\nExperience with Python, pytest, Django, FastAPI, REST\n\nExperience with Swagger and/or Postman\n\nExperience with Playwright or other E2E testing frameworks\n\nExperience with Cloud computing (Ideally AWS, e.g. EC2, S3, EKS)\n\nMore reasons to join us\nFlexible working hours and approach to work: fully remotely, in the office or hybrid\n\nProfessional growth supported by internal training sessions and a training budget\n\nSolid onboarding with a hands-on approach to give you an easy start\n\nA great atmosphere among professionals who are passionate about their work\n\nThe ability to change the project you work
