Software Development Engineer - Mobile & Commerce (Apprentice)

We are looking for a Software Development Engineer in Test Apprentice to join our Quality Engineering function for a structured 12-month apprenticeship. This full-time apprenticeship is designed for someone who wants to build a strong foundation for a career in software engineering.

Apprentices will work on real testing and automation initiatives that directly contribute to product quality, supported by mentorship, technical guidance, and structured learning throughout the programme. They will work alongside experienced SDETs and software engineers while developing practical knowledge of automation frameworks, API testing, defect analysis, CI/CD processes, and software quality practices.

Programme Details:

• Work Type: Apprenticeship
• Department: Engineering
• Sub Department: SDET
• Duration: 12 months
• Programme Start: September 2026

Responsibilities:

• Youll be placed on one team with one charter. Depending on where you land, that could look like: -
• Domain services in Go - designing protobuf contracts, implementing ConnectRPC handlers, and taking a service from ADR to production behind a flag. -
• Ledger and accounting- posting commerce events into a double-entry ledger in real time, building chart-of-accounts translation, and shipping journal APIs that external systems can read.
• Payments infrastructure- provider integrations, capability registries, idempotency and replay semantics for operations that must never double-charge. -
• Document rendering - a cross-runtime templating engine with a conformance suite that keeps Go, JS, and Dart implementations honest. -
• Developer tooling and MCP- protobuf-first code generation, manifest generators, and governance annotations that let AI agents call our APIs safely.
• Youll write ADRs, review other peoples designs, and carry your own on-call context for what you ship. Interns here merge to main in week two.

Requirements:

• Youll be a strong fit if you have: -
• A completed term in a recognized open source mentorship or contribution program, with merged and reviewed work in a real project - we will read your PRs.
• Working fluency in Go, or demonstrated depth in another systems language plus evidence you pick things up fast.
• Comfort with distributed systems fundamentals: idempotency, retries, consistency models, and what happens when the network lies to you.
• Familiarity with containers and Kubernetes at the level of "I have debugged why my pod wont start."
• The habit of writing things down - design docs, issue threads, commit messages that explain why.
• Graduation timeline that allows a full-time conversion at the end of the term.
• Signals we weight heavily - Sustained contribution to a single project across many months.
• Public review threads where you argued a position and changed your mind well.
• Anything youve built that handles money, correctness invariants, or multi-tenant isolation.
• Conference talks, blog posts, or upstream spec proposals (SEPs, KEPs, RFCs).
• Curiosity about the business problem underneath the ticket.

What the six months look like:

• Weeks 1-3: Environment, codebase tour, and a scoped starter charter that touches production. Y
• Weeks 4-16.: Your primary charter. One substantial piece of the platform that is yours to design, build, instrument, and ship. Youll present the design to the org and defend the tradeoffs.
• Weeks 17-24: Hardening, migration, and handoff - or extension into a second charter if the first lands early. Conversion conversations begin around week 18.
