Senior Software Engineer - MSX Compute Workflows in London

Imagine building the platform that powers infrastructure for 9,000+ engineers worldwide — managing a fleet of over 110,000 servers across global datacenters. Every service and product that clients rely on runs on infrastructure managed through systems you'll help create. Join the Compute Workflows team within Managed Systems Experience (MSX), where we're building the unified platform for infrastructure lifecycle management.

Today, the team manages the full lifecycle of the compute fleet across data centers and public cloud (AWS, Azure & GCP). Tomorrow, we're evolving it into a service-aware platform: a single pane of glass where application and service owners can manage not just their infrastructure, but their services, container workloads, and operational dependencies — all in one place.

What you'll build

Our mission is ambitious: transform INFR from a compute provisioning tool into the unified management plane for all managed compute — bare metal, VMs, containerized workloads, and Kubernetes — across every environment we operate in. You'll build the backend systems and APIs that orchestrate this: service lifecycle workflows, container orchestration on the managed fleet, and the provisioning infrastructure that keeps 110,000+ servers running reliably. You'll work deep in the stack — designing robust APIs, scalable data models, and orchestration pipelines — while also contributing to the frontend. You'll write React/TypeScript as part of shipping complete features, though it's not the primary focus of the role.

Our Stack (100% Open Source)

• Backend: Golang, Python
• Infrastructure & Orchestration: Docker, Kubernetes, Airflow, Salt, Ansible, Chef
• Data: PostgreSQL, Redis, Kafka
• API: REST, GraphQL
• Frontend: React with TypeScript

What you'll do

• Own backend systems — design, build, and operate the APIs and services that power infrastructure and service lifecycle workflows end-to-end.
• Build scalable APIs (REST & GraphQL) that serve both the INFR UI and programmatic consumers across the engineering teams.
• Architect data models that represent the entire technology infrastructure — from bare servers to containerized applications — at massive scale.
• Drive workflow orchestration — design pipelines that coordinate complex, multi-step infrastructure and service operations reliably.
• Extend INFR to new domains — containers, services, and applications — as we evolve from infrastructure management to a unified compute platform.
• Identify and eliminate bottlenecks across provisioning, deployment, and lifecycle workflows.
• Collaborate with stakeholders to translate infrastructure and service ownership pain points into well-designed backend solutions.
• Contribute to frontend — we're a full-product team; you'll write React/TypeScript as part of shipping features end-to-end, though backend and infrastructure work is where you'll spend most of your time.
• Mentor and elevate — thoughtful code reviews, knowledge sharing, and raising the team's engineering bar.

What you bring

• Must-haves:
• Strong software engineering fundamentals with proven backend system design and delivery.
• Track record building and operating production APIs or services at scale.
• Strong communicator who can work across infrastructure and product boundaries.
• Self-driven problem solver who identifies issues proactively and designs practical solutions.
• Degree in Computer Science, Electrical Engineering, or equivalent experience.
• We'd be excited if you have:
• Infrastructure and systems experience — familiarity with how compute is provisioned, managed, and orchestrated (bare metal, VMs, cloud).
• Linux systems knowledge — comfortable at the OS layer: process management, networking, filesystem concepts.
• Configuration management experience with Salt, Ansible, Chef, or similar tools.
• Container and orchestration expertise — Docker, Kubernetes, or related technologies.
• Workflow orchestration — Apache Airflow or similar pipeline frameworks.
• Database design skills — schema design and query optimization in PostgreSQL or similar RDBMS.
• Distributed systems knowledge — you think about consistency, reliability, and failure modes at scale.
• Frontend familiarity — React or similar; you'll be expected to contribute, though it's not where the bulk of the role lives.

Why this role matters

You’ll work at scale — managing over 110,000 servers where high availability, latency-sensitive operations, and massive throughput aren't just buzzwords, they're daily requirements. The systems you build will define how the entire engineering organization provisions, operates, and evolves its compute infrastructure — and how that infrastructure becomes the foundation for services, containers, and cloud workloads as the platform strategy advances.

Our open source commitment

The company is deeply invested in open source. We've spent over a decade building critical infrastructure with open source technologies and giving back to the community. In this role, you’ll have opportunities to engage with global open source communities, contribute to projects you care about, and potentially lead initiatives that benefit the broader ecosystem.
