Sortrace | Computer Vision Engineer, Junior Frontend Engineer | REMOTE (Europe), hybrid Norrköping or Stockholm | Full-time | https://sortrace.com

Sortrace is a small cleantech AI company in Sweden. Cameras on waste collection trucks and trained vision models flag material in the wrong fraction when bins are emptied. Customers use our platform to review deviations, images, and insights.

We're hiring for two roles on a small team with short decision paths.

Computer Vision Engineer - Train, evaluate, and improve deep learning models for real-world image analysis on our existing platform (datasets, augmentation, architecture experiments, precision/robustness/performance). - Python; PyTorch or TensorFlow. ~3+ years hands-on CV/model work, or equivalent documented experience (professional, OSS, or serious personal projects). We care about what you've built, not only job titles. - Plus: edge inference, quantization, real-time video.

Junior Frontend Engineer - Build and improve the customer-facing web platform: TypeScript, React, Tailwind, Radix/shadcn-style components, Git. - Early career is fine—show something you've built (side project, school, first job) and how you made it. - We use coding agents (Cursor, Claude, etc.) heavily in day-to-day work; you should be comfortable adopting that workflow.

Compensation: monthly salary by agreement; equity/options possible.

Apply: jobs@sortrace.com or https://sortrace.com/careers, subject line with the role name. CV role: short note on CV experience + links to projects/GitHub. Frontend role: what you built, how, and a link or demo if you have one. Questions welcome; we reply to applicants.

Blockrotate | Senior Systems / Rust Engineer | Remote (US/EU timezones preferred) | Full-time | $130k - $170k + Equity

Blockrotate builds low-latency copy-trading and execution infrastructure for Polymarket and prediction markets.

Copy trading on prediction markets has strange market microstructure. Unlike deep perp DEXes (Binance, Hyperliquid), Polymarket orderbooks are bounded, often thin, and subject to severe adverse selection. When a high-volume leader buys, the book moves immediately. If followers lag by a few hundred milliseconds, or if a platform taxes every order with a 50bps fee, follower alpha drops to zero.

Most existing tools in this space either hit users with high per-trade taker fees or ask them to export and paste their master private key into a database. We took a different approach: isolated per-bot deposit wallets (non-custodial via EIP-1967/1271 proxies) and co-located autonomous Rust workers running delta-sync loops directly against the Polymarket CLOB.

Stack:

- Backend: Rust, Tokio, Axum, Protobuf over WebSockets, SQLite (WAL mode)

- Trading Engine: Custom Polymarket CLOB & Data API clients, EIP-712 signing, dynamic slippage ladders, momentum filters, circuit breakers

- Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS

What you’d actually work on:

- Squeezing latency out of the execution hot path (delta position calculation, order placement, nonce handling, fill verification).

- Building better execution protection: momentum filters to dodge toxic order flow, fill stabilization windows, and handling thin book liquidity without moving the market against yourself.

- Scaling worker orchestration: our C2 server talks Protobuf to distributed bot workers with monotonic sequence IDs and autonomous reconnect failover. As bot volume scales, we need to keep state reconciliation bulletproof.

- Investigating and exploiting prediction market quirks (rebate structures, orderbook snapshotting, MEV/relayer bottlenecks).

What we look for:

- Strong async Rust experience (Tokio, concurrency, practical memory management).

- Experience dealing with websockets, exchange orderbooks, or trading infrastructure

eventfirst | Senior Full-Stack Engineer | Berlin, Germany | REMOTE (CET) | Full-time | eventfirst.com

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.
