Role
Who you are
- 5+ years in software, platform, or DevOps engineering roles
- Strong coding skills across at least one of Node.js, Python or Bash; comfortable writing production-quality internal software, not just scripts
- Fluency with AI-assisted development - you use LLM-based tools daily and have a feel for where they accelerate work and where they don't
- Hands-on experience with Github Actions or similar CI/CD systems
- Infrastructure as Code experience, Terraform preferred
- Solid cloud fundamentals (IAM, networking, compute, managed services), AWS experience preferred
- Hands-on Kubernetes experience, EKS preferred
- A builder's instinct: you'd rather fix the underlying problem once than patch it repeatedly
Desirable
- Experience with workflow orchestration or data pipelines
- Familiarity with observability and monitoring tooling
- Exposure to high-scale or high-growth engineering environments
- Interest in shaping how a DevEx function is built from the ground up
What the job involves
- This is the first senior engineering hire on the DevEx team, which means you'll have real influence over what gets built, how the team operates, and what "great" looks like at SEON
- You'll work across Platform, SRE, and product engineering for designing golden path solutions, shaping CI/CD and GitOps workflows, and building internal software from scratch when that's what the problem needs
- Design and build internal tools and services that meaningfully improve how engineers work (from CLI tools and developer portals to lightweight internal apps)
- Shape and improve our CI/CD and GitOps infrastructure, including GitHub Actions pipelines and ArgoCD workflows on Kubernetes
- Define and maintain golden path solutions for provisioning, deployments, and environment setup that teams can adopt without hand-holding
- Identify and systematically eliminate operational toil across engineering
- Integrate AI-assisted workflows and LLM-based tooling into how the team builds and operates and actively bring that capability to the tools and solutions you ship to other teams
- Partner with Platform and SRE teams on infrastructure automation, and with FinOps on cost visibility and optimization tooling
- Partner with the Security team to embed compliance automation into the delivery pipeline (policy as code, automated checks, guardrails that scale)
- Document and measure the impact of what you build and use that signal to decide what to tackle next
