• RedLine Solutions is hiring a fully remote mid-level C#/.NET developer. We are looking at an early September start date. I'm posting this way ahead of time to try something weird: If you are an interested developer, please do NOT contact me directly. Instead, find someone who will vouch for you and have them send me your resume`. I do NOT need them to write a full-on recommendation--a simple, "Ross was a great developer and fun colleague. You should check him out" will be fine.

  1. Please make sure your contact information is on your resume`!

  2. We need a developer located within three hours of Pacific timezone.

  No, I'm not on some kind of power trip (yet). I just got my fill of automated application spam a long time ago; the tales I could tell. This is my modestly creative attempt to circumvent the AI's. Might be good practice for SkyNet, eh?

  We are not looking for a know-it-all. Instead, we desire a "wants to learn it all". We're a small company, but our System Architect / Dev Lead is seriously a unicorn. If he mentors you for a year or two, your career is golden with or without AI. Back in the day, I secretly believed I was one of the best around. Then I worked with Stephen. I've learned a ton from him, and I'm his boss.

  We're a small, agile, creative and laid-back team who work hard but value work-life balance. I take great pains to make it so. If you're smart, work hard, and love writing software, ask a friend or former boss to vouch for you and have them send your resume`.

  Here's a link to the official job listing:

• MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

  We make robots that autonomously construct buildings, starting with bricklaying.

  There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.

  We're looking for experienced software engineers for many roles. You can help us solve problems like:

  - Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

  - Modelling buildings in code and finding the right UI for operators to edit them

  - Designing systems for robots to drive safely and fully autonomously around a building site

  Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

  We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

• SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers

  SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

  Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

  We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

  In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.

  We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~550). Now we’re scaling the platform.

• ProxyBase (https://proxybase.xyz) | Rust Backend Engineers & Full-Stack Developers | Remote (Global) | Full-Time | $100k-$160k + Equity

  Hey HN, we’re ProxyBase. We’re building an API-first, fully headless SOCKS5 proxy network designed specifically for autonomous AI agents, LLM tool-calling, and large-scale web scraping.

  Most traditional proxy networks operate in a bit of a gray area—they buy bandwidth harvested from sneaky, hidden SDK bundles embedded inside free apps. We're doing things differently:

  100% Ethical Sourcing: We pay our node operators directly. People run our open-source CLI client to share their bandwidth and earn microcredits in real-time. It’s fully transparent, consent-driven, and compensated.

  Built for Swarms, Not Dashboards: AI agents and automated workflows can provision, utilize, dynamically route (via metadata in the SOCKS5 auth string), and settle proxy fees entirely programmatically using US based stable coins without ever touching a manual web dashboard.

  Our Tech Stack:

  Backend: Rust (Actix-web, SQLite/DashMap, WebSockets, Yamux stream multiplexing) Frontend / Desktop: React, TypeScript, Tauri (our client-side bridge app)

  What we're looking for:

  Backend Engineer (Rust): Help us scale our high-concurrency SOCKS5-to-WebSocket relay gateway and real-time ledger settlement engines. Full-Stack Developer (TypeScript / Tauri / Rust): Own our local proxy bridging software, client-side developer portal, and integration libraries. If you like systems-level programming (TCP/UDP, tunnel multiplexing, concurrent state) and want to work on clean, developer-first infrastructure, we'd love to chat.

  Drop us a line at

  jobs@proxybase.xyz with a bit about what you've built.
