Head of Engineering at Appnigma

About Appnigma

Appnigma helps B2B SaaS companies build and maintain native customer-facing integrations through their own integration factory. When a SaaS company closes (or tries to close) an enterprise deal, the customer almost always wants Salesforce, HubSpot, or another system wired into the product — with that customer's objects, fields, and business rules. Building that by hand burns months of eng time. Keeping it alive when APIs change burns more. Most teams either divert their roadmap or ship a thin connector that breaks.

We run the factory that builds those integrations, serves them inside the customer's product, and keeps them working. The customer owns the code and the mappings. Fixes arrive as pull requests, never silent edits. They decide what ships. Two ways to work with us: Managed (their team owns the roadmap and reviews the work; we run the factory) or Embedded (we sit with their engineers from migration to go-live; we review, they decide what ships).

Appnigma was founded in May 2025 by Sunny Chauhan (CEO, ex-Salesforce) and Amarjit "AJ" Singh (CTO). First customer shipped in September 2025. The team grew from 2 to 7 by January 2026. We raised a pre-seed in 2026. Customers on https://appnigma.ai/customers/ include Warmly, Salesbricks, Pylon, Hyperbound, UserEvidence, Seam AI, and Monk. On average, customers save 60+ hours of engineering time. Warmly's Salesforce app: about 2 weeks to build, 8 weeks kickoff to AppExchange (about 6 weeks in Salesforce security review), roughly 40 Warmly engineering hours. Salesbricks diverted zero engineering sprints.

Why this role

You lead engineering delivery for the factory. That means the systems behind every integration — app registration, auth, sandboxes, testing, versioning, deployment, per-customer monitoring — plus the SDK customers use from their product. Production work includes Salesforce managed packages that have to pass Salesforce Security Review. Reliability and security are the job, not a side quest.

A lot of the factory still has to be built. Delivery is real and paying, but the hard unsolved pieces are speed without regressions, full-data-flow test coverage, monitoring that catches schema drift before customers do, and hiring the next few engineers without slowing the ones we have. You write code, set architecture, raise the quality bar, and grow the team. Get to work with the founders.

What you'll own in the first 90 days

• Days 1-30: Get fluent in the stack and delivery process. Ship in week one. Trace how an integration request becomes a PR in a customer's repo. Write a short engineering assessment of rework and risk.
• Days 31-60: Fix the top bottlenecks: delivery speed, full-data-flow test coverage, per-customer monitoring and alerting, Security Review / on-call / incidents.
• Days 61-90: Set a 12-month technical roadmap with product. Lock in code review, release cadence, and a hiring plan. Make your first one or two hires or contractor additions.

Who this is for

• 7+ years building production software, with at least 2 leading a team or owning technical direction at an early-stage company
• Deep experience with APIs, OAuth/auth flows, background jobs, and multi-tenant systems
• Strong TypeScript (our SDK is TypeScript, with Python and Ruby clients)
• You have shipped and maintained third-party integrations at scale: rate limits, schema drift, retries, per-customer mappings
• You balance speed and rigor: ship fast, still own security, testing, and uptime
• You hire well, give clear feedback, and teach through code review

Nice to have

Knowledge of integrations: native customer-facing integrations across systems (Salesforce, HubSpot, and more), managed packages / AppExchange or marketplace apps, OAuth and APIs, schema drift and per-customer customizations, or how SaaS teams ship and maintain native syncs.

How we work

Fully remote (US), async by default, weekly sync, fast Slack and Loom. Small team, high ownership. No layers, no committees. Customers see our work in their repo and their CRM, so we ship in small tested steps. Fixed scope for customers, quoted upfront, never hourly.

Pay and benefits

Fully remote (US). Base salary: $220,000–$320,000, based on experience. Health, dental, and vision insurance. Unlimited time off, and we expect you to use it. Laptop and home-office setup. Get to work with the founders.
