Eleos Technologies (https://eleostech.com) | Remote Senior iOS Engineer | Permanently Remote (US-based applicants only) | Full time

Eleos Technologies is a growing company building communication software for truck drivers and the back-office workers who support them. We’re looking to scale up a second product engineering team to ship more advanced driver planning tools, automate outdated workflow, and a bunch of other wins to make drivers’ lives easier and more efficient.

We're looking for someone who has the experience to move fast on new stuff and knows how and when to pick their battles on old stuff. You'd be one of four iOS engineers at a company that's big enough to survive an economic downturn, but not so big you can't make immediate, direct impact that'll be seen and appreciated by the whole company. (We've also spent the last decade working really hard to make sure our tools, processes, and culture respect everyone's work/life balance. I'm the CTO and I don't text people on my team, and they don't text me, and that's true throughout.)

It's a native iOS app written in a mixture of Objective-C and Swift, leaning on Swift for new features. (But that said: if you chafe at the idea of maintaining or fixing bugs in battle-tested Objective-C that's paying our salaries, please look elsewhere!) We have about 1/3rd functional/UI automated test coverage and the rest is human-powered by our QA team.

If you're interested, please share your info via https://jobs.lever.co/eleostech/b4866f22-fab3-4f84-abec-6e74... and we'll get in touch!

Klutch AI (https://klutch.ai/) | Mobile Engineer | Seattle, onsite | Full-time

We’re building an AI platform for construction: offline-first mobile/web apps that automate jobsite workflows, understand documents and blueprints, and connect the field to the office.

Looking for a strong mobile engineer to own our React Native/Expo app for iOS + Android, plus parts of our TypeScript web app. Backend is Scala/Play + PostgreSQL.

You’ll build for real field conditions: no signal, gloves, sun glare, dusty tablets, large blueprints, high-res photos, and messy jobsite data.

Useful experience:

* React Native / Expo * Modern TypeScript web apps * Offline-first apps, SQLite, sync, conflict resolution * App Store / Google Play deployment * AI APIs: LLMs, vision, speech-to-text

3+ years experience preferred. Strong English communication required. Construction/logistics/field-industry experience is a plus.

Competitive salary, health/dental/vision, high autonomy, early team impact.

MixRank (YC S11) | Software Engineers | 100% Remote (Global) | Full-Time MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.

Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.
