Stack: TypeScript, React/React Native, PostgreSQL/PostGIS, Python + GDAL/NumPy for satellite imagery processing.

Small remote-first team, wear multiple hats. Quarterly in-person meetups.

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

Saildrone is the world's leading collector of ocean-related in situ data via uncrewed vehicle, above and below the sea surface. We work with navies across the world to deliver insights about waterways, contribute to safety of life at sea, and mitigate illegal fishing and trafficking. Additionally, we work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, or counting biomass to establish fishing quotas.

Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just announced a large partnership with Lockheed Martin[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand and secure our planet.

Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.

In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

You can see a list of open positions on our career page: https://www.saildrone.com/careers

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

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.

We are hiring skilled 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 have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. 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 ambitious to get outcomes for our customers and their constituents. 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.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

You'll be working on the hard parts of getting LLMs to construct knowledge graphs users can actually trust: entity extraction from dense regulatory documents, grounding outputs with verifiable citations, and turning unstructured data into clear recommendations.

Stack: TypeScript/Python, React on TanStack, PostgreSQL, Kubernetes on GCP. We have traction and are moving fast in 2026. Competitive salary and meaningful early-stage equity.

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time | starbridge.ai

Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini.
