Trunk | https://trunk.io

Marketing Lead (Developers) - Remote friendly | Forward Deployed Engineer- Software Engineer II | DevRel Engineer - San Francisco| Staff Full Stack Engineer - San Francisco | Sr Full Stack Engineer - San Francisco

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.

Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions

Profitmind | Web Scraping Junior Developer | Remote or Pittsburgh | $90-110k | Full-time | https://www.profitmind.com/

At Profitmind, we're building massive-scale ecommerce datasets to use in AI training/inference, and we need a junior engineer to help develop the scraping infrastructure for product data. You'll be reverse-engineering undocumented APIs, handling anti-bot systems, and dealing with edge cases like pagination limits, rate limiting, and sites that change their protection schemes without warning. It's fun work! The technical side involves analyzing a site's network requests, deobfuscating and reading obfuscated javascript, and implementing simple HTTP request scraping to full browser automation. You'll also work on the infrastructure layer: state management for resumable scrapes, deduplicating products, data integrity, and monitoring systems to detect when sites change.

The work you'll be doing is in the hot path of our company, so the systems you will build need to be performant and maintainable. You should have solid Python skills and experience scraping ecommerce websites and APIs. You should also like the slightly-obsessive investigative nature of the work.

If you worked in scraping or botting in the past, please hit me up!

Machine Learning Engineer - FUTO Keyboard

FUTO Keyboard is a privacy-first software keyboard for Android. Every prediction inference routine runs entirely on-device; no user data can ever leave the device. We support over 150 keyboard layouts and languages, and over 700 layout + language combinations (not all of them include dictionary or predictions)

Swipe typing is an important part of the mobile typing experience for many. Applying machine learning here poses a unique challenge due to the requirement of needing to support so many layouts and languages, as well as user-added personal dictionary words (or even layout customizations!), with limited data. We have previously collected and publicly released a US English QWERTY dataset: https://huggingface.co/datasets/futo-org/swipe.futo.org/

We are looking for a machine-learning researcher or engineer to work through these challenges and help us improve the swipe typing experience in FUTO Keyboard.

We use vision models to extract and structure data from tax documents and automatically populate legacy tax software, saving CPA firms hours of tedious data entry per tax return. Firms are coming to us faster than we can build - our next tax season is already 10x the size of October's, and we have a waitlist for several X more.

We just raised a $5.1M seed round and are building a small, senior, in-person team. We believe in everyone talking directly to customers, and getting into the workflow themselves (i.e. learning how to do tax returns). We like to work together all day, whiteboard new ideas, get lunch together in person, and get drinks after work.

Shorebird | Mid-Senior Systems/Runtime (C++) Engineer| REMOTE (North America) | Full-time | $160-230k + equity + benefits | https://shorebird.dev

Flutter/Shorebird founder here. Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. We offer Flutter-related SAAS used by 1000s businesses globally, on track to profitability early 2026.

As part of our over-the-air updates “code push” product, we’ve built a custom compiler and runtime for the Dart language, primarily written by me (founder/CEO). Now that we have thousands of customers, I have many other responsibilities and need to bring on a fulltime engineer (you!) to take over primary responsibility for all of our C++ code (Dart & Flutter forks, custom runtime, compiler, etc.) and evolve it further than I could alone. Together, you and I will add obfuscation, improve our interpreter, possibly re-write method dispatch, etc. You don’t need to be a compiler/runtime expert. You do need to be capable of working on large open source projects, be comfortable with C++, want to work at a startup, work well independently (we’re remote) and want to learn and work on lots of different areas of code.

If you’ve contributed at least a little to WebKit, Godot, Firefox, or any other large open source project, are compiler/runtime curious, and want to work at a growing startup, you will likely find this role extremely rewarding.

We’re a small, senior team, making something people want. Tech: GCP, Cloudflare, React, Dart, C++, Rust. Shorebird operates almost entirely in the public over Discord. https://discord.gg/shorebird

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US) We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

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.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

We're looking to build our in-person team in NYC but also open to remote!
