Senior Platform Engineer

Your Role

As a Senior Platform Engineer, you’ll own the infrastructure, pipelines, and tooling that underpin how Walr’s engineers build and ship software. Working within a small, focused platform team, you’ll be hands‑on in everything from cloud infrastructure to CI/CD to observability — with a clear north star: developer experience. You’ll measure your success in the same way we do: cycle time, build performance, and the confidence our engineers feel in the systems they rely on. This role is about leadership in execution, ownership of outcomes, and shaping your product’s future.

How You’ll Make an Impact

• Technical Excellence

• Design, build, and maintain Walr’s cloud infrastructure on Microsoft Azure using Infrastructure as Code (Bicep), ensuring environments are consistent, auditable, and scalable across multiple regions.
• Own our CI/CD pipelines (GitHub Actions) end‑to‑end, from authoring and optimizing pipelines to establishing release engineering standards that enable fast, reliable, low‑friction deployments.
• Implement and evolve our observability stack, building out logging, metrics, tracing, and alerting solutions that give engineers clear signal when things go wrong and confidence when they don’t.
• Champion developer experience as a measurable outcome — track and improve key indicators such as build times, pipeline duration, and deployment frequency, treating the engineering team as your customer.

• Proactively identify and resolve infrastructure and platform issues before they become incidents, owning system reliability with an SRE mindset.
• Evaluate and introduce tooling — including AI‑native and agentic developer tools — that meaningfully accelerates how engineers work, with a bias for evidence over enthusiasm.
• Document platform capabilities and decisions clearly, reducing tribal knowledge and enabling engineering teams to self‑serve with confidence.

• Partner closely with backend and frontend engineers across squads to understand their pain points and translate them into platform improvements.
• Informally mentor engineers on platform and DevSecOps practices, raising the waterline of infrastructure literacy across the engineering organization.
• Contribute to security and compliance posture (SOC 2, ISO 27001), working alongside the engineering leads to ensure platform practices meet our obligations without creating unnecessary friction.

Skills That Set You Up For Success

• 5+ years of experience in platform, infrastructure, or DevOps engineering in a cloud‑native environment.
• Expertise in Microsoft Azure — including Azure Container Apps, Azure Functions, AKS, Service Bus, Cosmos DB, networking, and identity.
• Strong proficiency with Infrastructure as Code using Terraform or Bicep, with a focus on maintainability and reuse.
• Experience designing, building, and optimizing CI/CD pipelines, preferably with GitHub Actions.
• Deep understanding of containerization (Docker) and orchestration.
• Experience implementing observability solutions — structured logging, distributed tracing, metrics dashboards, and alerting (Datadog, incident.io, Sentry).
• A demonstrable commitment to developer experience, ideally with experience measuring and improving engineering throughput metrics.
• Excellent communication skills — equally effective writing a runbook, explaining a trade‑off to a product team, or raising a concern with leadership.

Bonus Points For

• Microsoft certifications (Azure Administrator, DevOps Engineer Expert, or Solutions Architect).
• Experience with FinOps and cloud cost optimization practices.
• Background in SRE disciplines — SLOs, error budgets, and structured incident management.
• Hands‑on experience with AI‑native or agentic developer tooling, whether adopting, evaluating, or building it.
• Scripting proficiency in PowerShell, Bash, or Python for automation and tooling work.
