Senior Software Engineer, Billing

About Docker
Docker has been one of the most loved brands in developer tooling, trusted by more than 20 million monthly users and over 20 billion container image pulls. From solo founders to the world's largest companies, developers rely on Docker to build, share, and run their applications across our suite of products including Docker Desktop, Docker Hub, and Docker Scout. We are a globally distributed, remote-first team building the tools that define how software gets built and delivered. As AI agents redefine software development, Docker is at the center of that shift, providing the sandboxed environments, verified images, and secure infrastructure that make autonomous workflows trustworthy by default.

We're building AI-native development practices into how this team works at a foundational level. That means infrastructure design needs to account for a new kind of collaborator: AI agents that generate, deploy, and operate software. The Senior Software Engineer, Billing on this team will keep systems running, help define what safe, observable, AI-assisted infrastructure operations look like in practice, and model that standard for the rest of the team.

What you'll work on
The Billing Platform Engineering team owns the systems that make Docker's commercial model real. You'll work on problems like:
How do we design infrastructure that makes AI-generated deployments safe to ship and easy to roll back?

How do we instrument billing systems so that failures — billing miscalculations, entitlement gaps, payment errors — are detected immediately and unambiguously?

How do we build infrastructure that scales with usage-based billing workloads without manual intervention?

How do we make the developer experience on this team faster and more reliable — local environments, CI/CD pipelines, deployment tooling?

Responsibilities
Own and evolve the infrastructure supporting Billing Platform services: compute, storage, networking, CI/CD, and observability

Design and maintain IaC (Terraform) for billing system infrastructure on AWS; contribute to module patterns and standards for the team

Build and own observability systems — metrics, logging, alerting — with a focus on billing accuracy and payment reliability

Implement deployment patterns and runbooks that work well in an AI-agent-assisted development workflow: clear rollback procedures, safe promotion gates, automated validation

Partner with software engineers on service design — bringing infrastructure constraints and operational requirements into the conversation before code is written

Identify systemic risks in the team's systems and drive improvements, including work that reaches into adjacent teams or services

Participate in incident response for billing system issues. This role may require participation in an on-call rotation to provide support outside of standard business hours, including evenings, weekends, and holidays, as needed.

Mentor engineers on the team; your technical judgment should help raise the bar for how the team builds and operates

Qualifications
6+ years in platform, infrastructure, or SRE roles supporting production SaaS systems at scale

Strong AWS expertise: ECS or EKS, RDS (Postgres preferred), networking, IAM, cost management — you've operated these systems under real load and real incidents

Strong Terraform skills; you've built reusable module patterns and can improve the ones a team relies on

Experience building and owning observability stacks (Datadog, Grafana, or similar) for production services — not just using them

Strong familiarity with CI/CD systems — Jenkins, GitHub Actions, or equivalent — including pipeline design and developer experience

Kubernetes at an operational and architectural level

A track record of identifying systemic risks and driving improvements within your team and adjacent systems

Security-first mindset: threat modeling,
