Giga · San Francisco, CA · 2 wk ago

On-siteEngineering$200k–$350k/yrFull-time

About the role

This role is on-site in San Francisco in the Dogpatch neighborhood.

Industry

Giga has recently raised a $61M Series A and is working with Fortune 500 customers to deploy the next generation of customer experience - real-time AI agents that can understand emotion, resolve issues instantly, and scale across the world's largest enterprises. Industry leaders like DoorDash trust Giga with their most complex support and operations workflows across voice, chat, and email, in high-stakes regulated environments where accuracy and compliance matter.

The Role

We're looking for backend engineers to build the infrastructure and systems that power our AI agents. You'll work across the stack, from data pipelines and analytics to real-time agent systems, shipping features that directly impact how our customers operate. This isn't a role where you'll be handed a spec and asked to execute. You'll own problems end-to-end: figuring out the right approach, building it, and iterating based on what you learn.

What You'll Work On

Analytics rewrite: Migrating our analytics service to ClickHouse and rebuilding it to scale through our next 10x of growth
Hallucination detection: Improving our detection systems with the goal of driving hallucination rates toward zero
Browser use agent: Scaling, stabilizing, and adding features and accuracy to our browser use agent in lieu of formal customer APIs

Tech Stack

Backend: Python (Django/FastAPI), TypeScript (Node.js)
Infrastructure: AWS, Modal, Kubernetes, Postgres
Frontend: TypeScript, Next.js (you'll interact with this, but it's not the focus)

Qualifications

4+ years building backend systems, ideally at companies where reliability and scale mattered
Comfortable with ambiguity: you can take a loosely-defined problem and figure out what to build
Write clean code and care about getting the details right, but also know when to ship
Want to work on hard problems with a small team where your work has obvious impact
Excited about AI agents and the infrastructure challenges that come with running them in production

Perks & Benefits

Catered lunch daily
Dinner stipend $500/month
Wellness & commuter benefit (gym, fitness classes, mental health)
401(k) plan
