We were recently acquired by Digital Speed, a complementary product & engineering agency. Together we partner with global clients to ship dependable, high-quality outcomes.

Where do you fit in?

You’ll join as a foundational engineer in London, working closely with agency leadership and client architecture teams. You’ll shape the SDK Factory: templates, generation workflow, quality gates, and release mechanics - then help hand it over through clear documentation and knowledge transfer.

This is a role for someone who enjoys breadth and ownership: context-switching across languages, improving pipelines, and collaborating across teams.

Responsibilities

• SDK templates & generation: Design reusable, idiomatic templates and code-gen configs for multiple languages (initially Java, .NET, Python; later TypeScript/Go).
• CI/CD & quality gates: Implement build matrices and release gates (lint/format, tests/coverage, SBOM, artifact signing, SemVer tagging).
• Packaging & publishing: Ship to artifact repos (e.g., Maven/NuGet/PyPI via Nexus/Artifactory) with signed, traceable releases and clear release notes.
• Portal integration: Expose SDKs via a simple download/manifest endpoint and ensure links & version badges remain stable.
• Reliability & DX: Timeouts, retries, pagination, and auth ergonomics that feel natural per language.
• Collaboration & handover: Work with client Architecture/Platform teams; produce run-books, recorded walkthroughs; lead reverse-demos so teams can operate independently.
• Continuous improvement: Reduce build times, remove toil, and keep outputs deterministic and reproducible.

Characteristics

• Simplify: Turn messy specs and pipelines into clear, repeatable systems.
• High-performance: Care about reliability, observability, and regression safety.
• Collaborative: Give/receive reviews; document decisions; unblock others.
• First-principles: Handle ambiguity and make trade-offs explicit.
• Ownership: Proactive, organized, and comfortable leading end-to-end.
• Developer-first: Empathy for SDK users; optimise for the “getting started” path.

Requirements

• 5+ years building production software (libraries/SDKs/dev-tools a plus).
• Proficiency in at least two of: Java, C#/.NET, Python, TypeScript (Go a plus).
• Solid grasp of OpenAPI 3.x and turning API definitions into usable clients.
• Comfortable with CI/CD (GitHub Actions and/or Jenkins), git, and code review.
• Experience publishing to Maven/NuGet/PyPI and managing artifact repos (Nexus/Artifactory).
• Working knowledge of semantic versioning, release notes, and changelog hygiene.
• Basic security hygiene: artifact signing, checksums, SBOM mindset.
• Right to work in the UK; fluent in written and spoken English.
• Exposure to OAuth/OIDC, mTLS, and PKI basics.
• Prior agency/consulting experience and/or regulated industries (finance, automotive, tech).
• Familiarity with developer portals and distribution pipelines.
