Carma (YC W24) | Founding Head of Engineering, Founding Full-Stack Engineer | San Francisco, CA | ONSITE | $175K–$450K + 2.0%–5.0% equity

Carma (https://www.joincarma.com/) is an AI-native operating system for enterprise fleet operations. Fortune 500 construction, electrical, and disaster restoration fleets run thousands of commercial vehicles on our platform in production today. When a truck breaks down, gets recalled, or sits idle, our software detects it, builds the workflow, and drives it to resolution automatically. Ship a feature in the morning; a fleet manager in the field is using it within the hour.

Why it's technically interesting: real-world software with messy, adversarial data — telematics streams, OEM recall feeds, vendor invoices, DOT compliance — fused into workflows that AI agents execute. The incumbents in this multi-billion-dollar market ship on decade-old stacks. We raised a $5.5M seed from Y Combinator, Soma Capital, and the founders of Superhuman, and we're driving toward a Series A.

Stack: TypeScript end-to-end — React, NestJS, PostgreSQL + Prisma, AWS.

Two founding roles, both heavy on ownership:

1) Founding Head of Engineering: $300K–$450K + 3–5% equity. Hands-on technical leader: the majority of your time writing production code, plus owning architecture, standards, and technical direction. Explicitly not a people-management track.

2) Founding Full-Stack Engineer: $175K–$275K + 2–3% equity. Own product surfaces end-to-end: ambiguous problem statement → scoped design → shipped to enterprise users.

Onsite in SF six days a week, early-stage pace, high ownership and high expectations. Our process is fast, strong candidates go from first conversation to offer in days, not months.

Email suleyman@joincarma.com with 2–3 lines on the hardest system you've shipped end-to-end. We reply to every thoughtful email within 24 hours.

Prolific Machines | Senior Software Platform Engineer | On-site mostly (Emeryville, CA) | Full-time | $160k–$210k + equity

We use light to control how living cells produce therapeutic proteins — optogenetic cell engineering, custom illumination hardware, and real-time ML bioprocess control — to drive down cost and scale up production of next-generation therapies.

With our technology scaling from the lab to the real world of biomanufacturing, we're now hiring a foundational software engineer to build the platform tying together our hardware, firmware, cloud, and internal tooling — high ownership over architecture and direction. This is a systems role across the hardware/software boundary (not web/SaaS), working directly with embedded, mechanical, data, and even bioprocess engineers.

Looking for: strong systems thinking; Python + one of TS/Go/Rust; cloud-connected services; comfort interfacing and debugging software against hardware (serial, TCP/IP); Linux. MS + 5 yrs or BS + 7 yrs. Bonus: Industrial IoT (MQTT Sparkplug B, OPC UA, SCADA/MES), regulated-industry data integrity (21 CFR Part 11, GAMP 5), or embedded C/C++.

Anyfin | Full-Stack, Backend (Go), Data Engineer | Stockholm, Sweden | ONSITE 3 days/week | Full-time | Relocation + visa sponsorship

What happens when you get a number wrong?

In most systems, you log an error and move on. At Anyfin, a wrong number is someone's loan application.

We're a profitable Swedish fintech that helps people refinance expensive consumer loans at better rates. Small team, regulated industry, which sounds like a recipe for slow, cautious engineering. It's the opposite. The regulation sets the floor, not the ceiling. Above that floor, we experiment, ship, break, learn, and ship again.

We're building real-time credit decisions using ML models on GKE, Go and Python on the decision layer, TypeScript/Node.js on the API, React on the frontend, BigQuery and dbt for data. Interesting stack, interesting problems, and because we're small, you're close to all of it.

Our co-founder Sven is back leading eng and hiring directly. No recruiter chain, no committee. Short feedback loops. Real ownership. No one to hide behind.

- Designing and implementing distributed systems in a security context

Who we're looking for: Our priority is a lead engineer, but we'll happily take strong juniors if the mindset is right. The key thing: we're not looking for a pure coder, but for someone who enjoys looking at a problem architecturally as well.

- Deep expertise in a technically demanding area. Classic fits: distributed systems, cryptography, networking. Equally welcome: compilers, OS internals, formal verification, database internals — or any other field where you have real depth.

- Solid engineering skills in Go, Python and/or Rust

- German & English, C1 minimum

The role is fully remote within Germany, with very little travel required.

Bubblehouse | Integration Engineer | FULLY REMOTE | $70–110k/yr | Full-time

We're a fast-growing custom & private loyalty platform powering programs for household-name brands. Small, fully-remote team across the US and Europe.

We want a detail-obsessed, autonomous mid-to-senior engineer (~5–10 yrs) to investigate customer problems, drive integrations end to end, and own the specs that make them work.

You will use AI to its fullest, but will keep a very close eye on whatever that AI produces. As such, this role is less about coding, and more about figuring out what to build, how that best fits into the system, and why things are as they are, debugging edge cases, anticipating failure modes, talking to people, and plain old debugging.

Tech-wise, we're running on Golang, and using custom database engine on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap'ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We're doing that in production. Zero lines of React, few third-party dependencies carefully vetted, every line of JavaScript manually written, and we render HTML server-side like it's 2005.

You: detail-oriented to a fault, self-motivated about investigation/debugging work, comfortable spoken English for client calls, available 9am to noon in New York time.

We are straightforward, driven, personal, and a little messy. We all care, and we expect you to care too.
