Arboreal Management | Principal Software Engineer | Seattle, WA | ONSITE | $160–180k

We are a fast growing tech enabled property management company. We manage 9,000+ apartments across the Pacific Northwest, growing 40-50% p.a. Over the last several years we've been building our own software platform, Maynard, to run more and more of the company.

We're looking for an exceptional senior engineer to become the principal technical builder on a very small team.

We're not a software company and don't want to become one. We don't plan to build a big engineering organization. Instead, we think a small number of very good engineers can have enormous leverage inside an operating company where most of the existing software is pretty bad.

There's a lot to build. Maynard already touches leasing, property operations, communications, maintenance, document processing and reporting. We're now working on things like payments and treasury, replacing parts of our property management ERP, and using LLMs to automate workflows that previously required people reading documents or moving information between systems.

Our stack is mostly TypeScript/Node, SvelteKit, Postgres, Azure and Cloudflare. We're not particularly concerned whether you've used those exact technologies. You'd work directly with me (CEO, CS/math background) and a small team. This is primarily a builder role, not an engineering management job. We're looking for someone who is very good at designing and building production software, wants a lot of ownership, and likes the idea of their work changing how an actual business operates within weeks rather than years.

AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.

Lokker.com | Senior Backend Engineer, Scanning Infrastructure | REMOTE: North America / Europe, UTC-8 to UTC+2 | Full-time

Lokker is a privacy platform that helps organizations understand and control what is happening across public-facing infrastructure: websites, browser-side applications, scripts, pixels, cookies, tags, forms, SDK/API calls, and browser-side data flows.

We are hiring a senior backend engineer to own and continue to scale Lokker’s scanning infrastructure. This role focuses on backend systems for high-volume website scanning, browser automation, distributed scanning, networking, reliability, performance, and cost optimization.

IMPORTANT: A key requirement for this role is substantial, hands-on production experience with browser automation, headless browsers, crawlers, scanners, synthetic monitoring, scraping infrastructure, or closely related technologies. This is not a general backend role, and we can only consider candidates who have already built, operated, or scaled systems in this domain.

Other relevant experience includes distributed systems, queues/orchestration, high-scale backend services, HTTP/TLS/DNS, proxies, CDNs, WAFs, bot detection, and fingerprinting.

Production experience in Go, Rust, TypeScript/Node.js, C++, or similar.

Proxybase | Backend Systems Engineer (Rust) | Remote (Global) | Full-Time | https://proxybase.xyz

Hi HN,

I’m the founder of Proxybase [0]. We’re building an agentic SOCKS5 proxy network designed to bring transparency and ethical sourcing to the residential proxy market.

Quick note to anyone who applied last month: First off, thank you to everyone who reached out. We got hit with way more high-quality applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to respond than we should have. If you applied last month and haven't heard back, we're genuinely sorry for the delay, we are actively reviewing those responses alongside this batch.

Why Proxybase? Historically, the residential proxy industry has been pretty shady, think hidden background scrapers bundled into TV firmware or mobile apps, combined with predatory payout systems that hold provider funds hostage for months.

We’re taking a different approach:

Fully Open-Source Clients: Our GUI [1] and CLI [2] are completely open-source so anyone can inspect and audit what we run. Explicit Consent: Providers knowingly opt in. No stealth bundling. Instant, Fair Payouts: $1 minimum payout threshold sent directly to provider wallets via US stablecoins—no holding funds to farm interest.

What We’re Looking For We’re looking for a Backend Systems Engineer (Rust) to help us build out our asynchronous SOCKS5 routing infrastructure, daemon node orchestration, and automated bandwidth allocation pipelines.

Stack: Rust (Tokio / Axum), SOCKS5 protocol, Linux systemd daemons, SQLite Location: Fully Remote (Async-friendly, flexible timezone) Compensation: Competitive salary + equity (USD or stablecoin options available)

If you're interested in building infrastructure for an industry that desperately needs better standards, send an email to jobs@proxybase.xyz with your GitHub/resume and a short note on what you’ve been working on lately.

I’m also around in the comments if you have any questions or feedback on what we're building.
