FusionAuth | Principal Software Engineer, Senior Java Engineers, Account Executive, Customer Support Manager | Varies between REMOTE (in USA, also in Europe but only for the account exec position) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Principal Software Engineer it is 225k-270k, but the Euro positions don't have them :(
At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.
There are a lot of companies in the auth space, but we feel like we have something special:
* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Datamint | Rust Systems Engineer, Browser Security | Remote (Global) | Full-time | $120k–$170k + Equity | https://datamint.xyz
We build high-throughput crawling and structured data extraction infra designed for AI agents and LLM pipelines.
If you’ve built scrapers recently, you already know the state of the market:
- Traditional proxy providers (Bright Data, Oxylabs, Smartproxy, Proxybase) give you raw IPs or massive unparsed HTML blobs, leaving you to deal with DOM bloat, token waste, and brittle parsing pipelines.
- Modern tools like Firecrawl or Jina made clean Markdown extraction easy for hobby setups, but they often struggle when you throw heavy SPAs, high-concurrency jobs, or hardened anti-bot walls (Cloudflare Under-Attack / Turnstile, Kasada, DataDome) at them.
- Rolling your own Playwright / Puppeteer cluster works until target sites deploy new JA4/TLS fingerprints, and your data team ends up spending 30% of their sprints fixing broken crawlers instead of shipping product.
We're tackling this by combining a low-latency Rust fast-fetch engine (JA4/TLS and HTTP/2 frame emulation) with an isolated stealth browser fleet, zero-code schema validation (JSON Schema/Pydantic), and native Model Context Protocol (MCP) support.
Trade-offs / where we fit: If you just need to curl a few static Wikipedia pages, a 10-line Python script is better and cheaper. But if you need reliable, structured data out of bot-defended sites without babying headless browsers, that's what we do.
We're looking for:
1. Rust Systems Engineer: High-concurrency network I/O, Axum/Tokio, TLS/BoringSSL fingerprinting, proxy routing matrices, and low-latency data pipelines.
2. Browser Security Engineer: Deep familiarity with browser internals (Firefox/Chromium source), canvas/WebGL/audio fingerprint evasion, CDP/WebDriver stealth, and familarity with anti-bot defenses.
Our stack: Rust, Next.js 16/React 19, TypeScript, hardened Firefox/dwx_crawler, Linux/Xvfb, SQLite WAL/Postgres.
If interested, shoot an email to jobs@datamint.xyz (or founders@datamint.xyz) with your GitHub, a project you built or broke, and what you find interesting in this space. No formal cover letter needed.

Qualcomm | Canada | Full Time | Remote(Canada)| QEMU
My team is looking to hire a software developer to help us design and extend QEMU support [1] for the Hexagon DSP [2]. We're looking for candidates who have experience coding in C, C++ or Rust* and who aren't afraid of rolling up their sleeves and poring over disassembled code. This particular architecture is a bit more challenging than most, because it's a bit unique. It's a VLIW [3], so it's a great opportunity to learn about an interesting architecture. Millions of Hexagon DSPs are out there, most are found in DragonWing/Snapdragon/DragonFly SoCs for Laptops, Android phones, cars and more!
We collaborate a lot with Open Source communities like QEMU, LLVM [4], the Linux kernel [5], and more. I love being able to work on Open Source software at my day job.
You can contact me directly (email addr is in my HN user link). If you don't have experience with QEMU - don't worry! Most of us didn't have any experience with it until recently, too.
The rest of the team you'd work with lives mostly in Canada, EU, US.
* Rust experience may serve the role well but we don’t (yet) have any product software in Rust.
