We're looking for a senior full-stack engineer, leaning backend, to build a new B2B product on the Helix team. You'll ship the APIs, integrations, and web experiences our business customers use every day, from how they communicate with us over WhatsApp to how they're billed and pay.

This is a small team that moves fast. You'll work directly with product and customers, own features from idea to production, and ship weekly. We value pragmatic engineering over elaborate architecture: simple systems that work, ship quickly, and are easy to change.

What you'll do:

Design, build, and ship production backend services and APIs in Python (Go welcome)

Build product-facing web features in React alongside the backend

Integrate with external platforms, starting with the WhatsApp Business API, plus messaging, CRM, and partner APIs

Ship the payment side of the product: checkout and invoicing flows, processor integrations like Stripe, webhooks, and keeping customer billing accurate

Own your services in production on AWS or GCP, including containers, CI/CD, monitoring, and cost

Work directly with product and customers to scope, ship, and iterate on 0-to-1 features

What we're looking for:

5+ years of software engineering experience, including 3+ years building production backend systems

Senior-level, hands-on IC who still writes and ships code every day

Strong Python backend experience (Django, FastAPI, Flask, or similar), or Go with a willingness to work in Python

Real product experience with React or a similar framework (Vue, etc.), leaning backend

Experience shipping integrations with third-party platforms and APIs in a B2B or SaaS product

Experience building product features that involve payments, such as integrating Stripe or another processor for checkout, invoicing, or billing

A track record of fast shipping at a startup or on a small team, with dated launches you can point to

Hands-on experience running services on AWS or GCP with containers and CI/CD

Able to work onsite in San Jose 5 days a week

Bonus qualifications:

Deeper B2B billing experience: usage or invoice-based billing, payouts, idempotency, and reconciliation

Experience with the WhatsApp Business API, Twilio, or similar messaging platforms

Early engineer at a B2B SaaS startup who helped take a product from zero to paying customers
