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++.

Paymail | Engineer | REMOTE | Startup Equity Only

Paymail is an invoicing and money transferring service over email. Because it's alot easier to send $50 to email@example.org than to send it to a long series of digits representing a branch and account number. In a way Paymail is an internet native payments competitor to x402.org. I'm the founder and I'm on a mission to make every bank your email provider. I spent the last year working for a banking outsourcing company and it gave me some good insights into what's possible in the FinTech world. I'm currently searching for a React+Typescript developer with good design instincts to give a huge chunk of equity to and become a cofounder of the company working with a well written medium sized React+Typescript codebase that represents our product.

Startups are busy but to get the product to an MVP stage is not very far away at all so it would suit someone looking for a potentially profitable side hustle or on a full time basis as well.

Stack: Stalwart, React, Typescript, Python, Rust, Postgres

Strobe Power | Founding Engineer | ONSITE (Brooklyn or SF) | https://strobepower.com

AI data centers are creating a massive new wave of electricity demand, and the grid is already stretched. Strobe is building an autonomous power company to help meet that demand: software that turns buildings, batteries, EVs, and generators into a distributed power plant that can buy, sell, and dispatch electricity in real time.

We’re a 6-person, well-funded team backed by top investors. This is early, high-ownership, and very real-world: the software you build will control physical assets and move money in energy markets. We are the only company actively trading distributed power in New York - the space is entirely new and unlocked by recent FERC regulation.

I’m looking for a staff engineer to own the data integrations and cloud infrastructure that make the whole system work. That means connecting to utilities, grid operators, OEM hardware, weather providers, and our optimization engine — then making sure it all runs reliably when market events are happening and dollars are on the line.

You’d work on things like:

* Wholesale market integrations with NYISO, CAISO, ERCOT: pricing, capacity markets, dispatch signals * OEM hardware integrations for monitoring, control, and telemetry * Utility data pipelines, including Green Button Connect / ESPI, interval usage, billing, and meter data from utilities like ConEd, PG&E, and SCE * Weather forecast pipelines feeding our scheduling engine * Event-driven AWS infrastructure using Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, Timestream, Amplify, and CloudWatch * Terraform IaC, observability, alerting, and the reliability work needed when downtime has real financial consequences

Good fit if you have deep AWS experience, have used Terraform seriously in production, and write a lot of Python. Energy experience is a plus, but not required. Experience with utilities, government APIs, OEMs, hardware, telemetry, or other “real world is messy” systems is very relevant.

Stack: Python, TypeScript, Rust, Terraform, AWS, GraphQL/AppSync, MQTT, Grafana. We use an AI-agent-optimized monorepo and are investing heavily in agent-enabled engineering efficiency.

Small team, no layers, high trust.

Apply: keeley@strobepower.com or https://strobepower.com/careers. Please mention Hacker News.

Obsidian Security | Staff Software Engineer | REMOTE (US) | Full-time | $176k-$196k + equity + 401k | https://job-boards.greenhouse.io/obsidiansecurity/jobs/51527...

We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector.

Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it.

Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling.
