What you’ll do
AI Innovator: Prototype and ship production AI features fast; extend our multi-agent orchestration; design private/sovereign data pipelines and dynamic indexing; collaborate tightly with founders to turn research into product.
Principal SWE: Own core platform architecture; design and scale distributed backends/APIs; build great DX (SDKs/CLI); lead reviews/mentorship; drive 0→1 projects with strong reliability and observability.
You might be a fit if you have
A track record taking systems from concept to scale and to revenue.
Deep backend/systems skill (Go/Rust/Kotlin or similar); strong CI/CD/testing discipline.
Experience with distributed, real-time data infra; privacy/security minded.
Hands-on AI product chops (CV, NLP, LLMs/agents) and bias to build/iterate quickly.
Clear communication, product intuition, and comfort working directly with founders.

CEF AI builds an AI-first data automation platform for secure, decentralized orchestration of agents that compute directly on encrypted data streams. We’re shipping original systems (not wrappers), with multiple tuned models (CV, NLP, LLMs) and a next-gen multi-agent data infrastructure. Small team, high ownership, low bureaucracy.

Pomelo Care is a multi-disciplinary team of clinicians, engineers and problem solvers who are passionate about improving care for moms and babies. We are Series B, with some notable investors like First Round and a16z. As a member of our engineering team, you will have the opportunity to shape the product, codebase, and culture at Pomelo for years to come. On any given day, you may:
- Write clean, elegant code to build new features and keep our platform humming
- Design new systems to enable Pomelo's clinical team to deliver personalized care to an expanding patient population
- Build a great mobile experience so pregnant women and new parents feel they have a support team in their pocket
Tools we use:
- GCP, Kotlin, Typescript, React, React Native, Terraform, Spanner DB, Big Query, DuckDB, Dagster, DBT, K8s
Personally, I've never had so much fun and learned so much at work. This team is phenomenal, so I recommend applying if you're looking to learn a lot and make a big impact in an important space.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS product or AI wrapper, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool new AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.
