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. 
    • HighLevel India Apprenticeship Policy:
    This Apprenticeship Policy is issued pursuant to and in compliance with the Apprentices Act, 1961 (as
    amended), the Apprenticeship Rules, 1992, the National Employability Enhancement Mission (NEEM)
    Guidelines (if applicable), and the National Apprenticeship Promotion Scheme (NAPS) Guidelines notified
    by the Ministry of Skill Development and Entrepreneurship.
