React Jobs - October 2026

We are applying AI to organize corporate events.

We are looking for a senior engineer with at least ten years of full stack experience, a strong focus on product and UX, and some experience building an AI chat based product.

Our tech stack is Typescript, React, Next.js and Tailwind. On the backend we use Drizzle with Neon, deployed and monitored via Vercel. Agents and background jobs are executed via trigger.dev. This gives us a killer DX because the entire tech stack supports preview branching. This allows coding agents to work in parallel on different features and verify their work independently very close to what will run in prod. CI is fast (2-3 min) and coverage is good enough to deploy to prod many times per day.

Please note that we are working remotely in the CET timezone. Having some remote experience is a plus.

We have pre-seed funding from a major US VC and are experienced founders. You’ll be working alongside the founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and will have a chance to shape the company, product and of course the engineering culture.

We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.

We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!

We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.

You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.

This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.

We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!

Open to contract work.

We're Australia's battery-backed electricity company. We fund, install and operate batteries on-site at small businesses, then supply their power at a firm, flat rate 20–40% below incumbents, making the economics work by optimising those batteries against wholesale prices. We're live with real customers. Team of six, backed by Systemiq and Black Nova; engineering includes Casey, who previously led Google engineering in Paris and Google Maps in Sydney.

We're AI-native: engineers, energy specialists and go-to-market colleagues all ship with coding agents. Each engineer owns a product end to end, from the commercial problem through to production. Flat structure, lots of ownership.

Areas you could own:

* Customer experience: quoting, onboarding and the customer app

* Metering and billing: turning high-volume interval data into accurate bills

* Energy-market and battery data: the market, weather and telemetry pipelines behind our decisions

* The agent-driven development platform the whole team builds on

Stack: TypeScript, React, Postgres, serverless. Intro chat, system design, an agentic build, then a day with the team.

Cardog turns raw vehicle data into facts you can check: VIN decode, market price, recalls, and what the car's own modules report. Insurers, dealers, manufacturers and the public bodies that register vehicles all use it. We're a small team and every engineer owns a whole area.

Data - Data Platform Engineer (Remote). Own the datasets: government files, manufacturer filings, dealer listings, signals from the vehicle. Decide which source wins when two disagree, and be able to prove it. SQL first, entity resolution, tens of millions of rows. Postgres, TypeScript, Workers, R2. - VIN Decode Engineer (Remote). Own decode accuracy. Read manufacturer filings line by line, write the patterns, and test them against millions of real VINs. For people who are obsessive about correctness. TypeScript, Postgres.

Design - Design Engineer (Remote). Own the component library and the screens built on it. Dense data, and making uncertain or missing values look uncertain. You design in the browser and you merge it yourself. React, Next.js, Tailwind. - Founding Engineer, Dealer Platform (Toronto / Remote). First engineer on software for dealer groups. Time in stores, then ship it the same week. Strong Postgres, multi-tenant.

Business - Account Executive (Toronto / Remote). Enterprise and public-sector sales cycles measured in quarters. Run technical first calls alone and pull your own numbers in SQL. - Policy & Standards Lead (Ontario). Represent us in the consultations and standards bodies writing the rules for vehicle data. Closer to counsel than comms.

Field - Hardware Engineer, Vehicle Interface (Toronto). Own the diagnostic-port device: board, firmware, enclosure, from bench to a unit on a dealer lot. C or Rust, CAN at the frame level, UDS/ISO-TP against real cars. - Forward Deployed Engineer (Ontario). Take named accounts from the first meeting to a running system. TypeScript, SQL, and some time under dashboards.

Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.

In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.

Founded 2023, ~16 people, $8M from Greylock, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample.

I'm the CTO and I read every application myself. Happy to answer questions in this thread.

Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.

We are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats.

Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.

Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant.

Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required.

Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.

Hedge is an AI-native insurance company. We started as a wholesale brokerage for specialty commercial insurance, where AI agents do most of the work of placing policies: reading messy submissions, chasing missing information, working with 100+ insurance markets, and moving accounts toward coverage.

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.

The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.

We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.

We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!

We’re hiring for 2 Senior Full Stack Software Engineers, 1 Machine Learning Engineer and 1 AI Product Manager in SF, and 2 Staff Full Stack Software Engineers in NYC. Engineers own projects end-to-end so full stack ability is expected.

Check out our open roles here: https://shepherdinsurance.com/careers Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis – If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.
