About the Team

HighLevel is an all-in-one platform for small businesses, distributed through a network of agencies. The Commerce org owns everything a business needs to sell, get paid, and keep its books straight: product catalog and inventory (PIM), checkout surfaces, payment provider integrations, invoicing and accounting, and the document platform that renders every invoice, estimate, and receipt the platform produces.

We run a Go domain tier behind ConnectRPC and protobuf, deployed on GKE with Istio mTLS in STRICT mode. Financial truth lives in TigerBeetle, with PostgreSQL carrying metadata. Authorization runs on a ReBAC substrate (SpiceDB/OpenFGA). Roughly 40 engineers across seven teams, each with a single clear charter.

This is a platform with real money moving through it and real merchants depending on it. The work is correctness-sensitive and the feedback loop is short.

Responsibilities:

You'll 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.
• You'll write ADRs, review other people's designs, and carry your own on-call context for what you ship. Interns here merge to `main` in week two.

Programme Details:

• Work Type: Apprenticeship
• Department: Engineering
• Sub Department: Mobile & Commerce
• Duration: 6months
• Monthly Stipend: 50,000 INR
• Location: Remote - India
• Programme Start: September 2026

Requirements:

You'll 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 won't 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 you've 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. You'll 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.
