The Role
Pantheon is looking for a Senior Software Engineer to join our Connectivity & API Transformation team. We're expanding an impressive and growing platform that powers hundreds of thousands of websites, millions of containerized resources, billions of monthly page views, and development tools that professional website developers use.
Our team owns the connective tissue of that platform: the federated GraphQL API that every Pantheon surface is built on, the network layer and discovery patterns that let our services find and reach each other, the orchestration layer that runs customer-facing automation, and the ongoing work of decomposing our legacy core into well-bounded modern services. It's a role with unusual leverage — the interfaces and pathways you design become the contract that every other engineering team at Pantheon builds against.
Pantheon's core company values are Trust, Teamwork, Passion, and Customers First. Additionally, the Pantheon engineering teams are built around a focus on collaboration, character, autonomy, and a no-blame culture. We're enthusiastic participants in several open-source communities and have real relationships with many of our most active customers.

What You'll Be Doing
Building and evolving Pantheon's unified API — a federated GraphQL supergraph (Grafbase, Federation v2) and the Go subgraphs behind it that serve our Dashboard and public API
Shaping how Pantheon's services find and reach one another — VPC and network architecture, service discovery strategy, and the connectivity standards our internal traffic runs on
Decomposing a large legacy Python monolith into well-bounded services, and owning the Cassandra data layer behind it — replication, backup, and disaster recovery
Designing and operating workflow orchestration at platform scale: GCP Workflows, Pub/Sub-driven job execution, and Go services on Cloud Run that run customer-facing automation
Setting the GraphQL, gRPC, and REST standards other Pantheon teams build against, and acting as a technical resource for initiatives across the org
Owning your team's production systems — tracking health with SLOs, resolving production issues, and balancing delivery speed against reliability
Supporting Pantheon as a member of our on-call engineering rotation and your team's alert response rotation
Raising the level of engineers around you through code review, design feedback, and mentorship
What You Need to Succeed
Significant work experience building and operating production services in Go, and the adaptability to work in a polyglot codebase — our stack also includes Rust and Python
Experience designing APIs that other teams depend on, with real judgment about schema design, versioning, and backward compatibility. GraphQL, gRPC, or REST at scale all count
Work-related experience with large-scale, high-traffic distributed systems, and with designing scalable and robust services in the real world
Experience carving services out of a monolith, or otherwise evolving a legacy system incrementally while keeping it running
Working knowledge of cloud networking fundamentals — VPCs, DNS, load balancing, and service-to-service authentication — and the judgment to make network boundaries a deliberate design choice rather than an accident
Understanding and working knowledge of Kubernetes, Terraform, CI/CD pipelines, and release engineering practices
Experience with a major cloud provider; GCP especially welcome
Experience leveraging observability tooling like Grafana Cloud, Prometheus, and OpenTelemetry to understand systems in production
Experience supporting live sites and participating in on-call
Clear communication skills and the ability to represent your contributions and ideas with clarity while remaining open and giving space to the contributions and ideas of others
Bonus Points
Hands-on experience with GraphQL Federation, a federation gateway or router (Grafbase, Apollo, Hive), or a schema registry
Working knowledge of Rust
Experience with Cassandra, or with running a stateful datastore in production — backups, DR, multi-region replication
Experience migrating off end-of-life language runtimes (for example, Python 2)
Hands-on experience with private service networking or a service mesh — Shared VPC, VPC peering, Private Service Connect, internal DNS, Istio/Envoy
Working knowledge of GCP Workflows, Pub/Sub, Cloud Run, Cloud Build
Working knowledge of AlloyDB, MySQL, Redis
Working knowledge of Docker, CircleCI, GitHub Actions, Vault
Working knowledge of WordPress, Drupal
What We Offer
We have all the usual perks and benefits but what we can really offer you is a fantastic work environment powered by an amazing team.
