Latitude AI | Software Engineer | Pittsburgh, Palo Alto, Dearborn, Remote (US) | Full-time | lat.ai

We make automated driving software. As an independent company owned by Ford we need to ship a consumer-facing product at scale & reliability not common for our space. Yet we have the freedom to move fast. 2026 is our first time shipping a customer fleet, so times are exciting.

Several open roles on the careers site: https://lat.ai/careers

But the _best one_ is on my team (Data Platform): https://grnh.se/12jfaoak1us. Looking for a generalist SWE with strong opinions about data modeling and storytelling. Our stack (BQ, various dashboard & notebooking tools, conversational analytics) is heavily used at the company for all decision-making. An ideal candidate would have product vision, help us adapt for deeper adoption, and guide customers to solve real problems (vs vanity metrics/dashboards or get stuck in XY-problems).

Very competitive pay; bonuses above the norm (levels.fyi seems to have a good bead). Visa sponsorships: yes. Outside-US hires/relocations: sadly no. Email in profile (or find me on dbt, Superset, k8s Slack), AMA.

We’ve had (human) agents asking us to accelerate our roll out plan because the days with Stellar are so much better than the days without.

We’re all builders. Everybody in our company still writes code. We have one role open:

We are looking for implementation leads that love working with clients. FDEs welcome as well.

This role is perfect if you:

* Want massive ownership at a small team

* Actually enjoy solving hard problems (real-time audio at enterprise scale)

Prior Labs | Berlin / Freiburg / NYC | ONSITE | Full-time | Multiple Roles

Tables power every financial model, clinical trial, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. €9M pre-seed from Balderton, with backing from leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.

All roles: https://jobs.priorlabs.ai

Prior Labs | Full Stack Engineer, ML Platform Hiring: Berlin | Salary: Competitive with top AI labs + meaningful equity | Relocation support | Full Time

Building the product that puts tabular foundation models into users' hands. React, FastAPI, Postgres. You'll work across frontend, backend, and directly with researchers shipping new model capabilities to production. 3+ years full stack, strong TypeScript and Python, experience with data-intensive applications. https://jobs.priorlabs.ai

Marker Learning - Founding Full Stack Engineer – Remote (USA) – 180-250k

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled. Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate.

Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your gh, linkedin, and resume and why you want this position to lucie@markerlearning.com. Please specify your location, if you are interested in full time, contract or open to both. Make the subject "Founding Engineer Application (I am not a bot)".

Preferred Networks | Tokyo or Remote in Japan | Full-time | https://www.preferred.jp/en

Preferred Networks is an AI company based in Tokyo working across the stack, from AI chips and computing infrastructure to LLMs and products. You may already know us indirectly if you've used software we've built, such as Optuna or CuPy (or Chainer, back in the day).

We are designing in-house chips (MN-Core series: https://mn-core.com/) and training LLMs (PLaMo series: https://huggingface.co/pfnet), and our team is actively hiring for two roles related to these endeavors:

- MN-Core LLM Serving Engine Engineer: Build software infrastructure to serve LLMs using our upcoming inference accelerator, MN-Core L1000.

[Apply here: https://open.talentio.com/r/1/c/preferred/pages/119173]

Both roles require relocation to Japan. We are happy to provide visa and relocation support.

Prophet Town LLC | Various Software Engineering Roles | US – Remote and Hybrid | English fluency required | Full-time | $150K-$260K annual total comp (multiple)

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds and still coding. Notable recent projects include internal tools for Anduril, and the original buildout (both auction site and operations infrastructure) of Voltage Park. This is a remote-first agency, but some projects involve onsite work.

I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.

Applicants must meet a high bar - I personally review every hire. In return you’ll get:

  * Flexibility and a low-bureaucracy environment
  * Clients that won’t treat the vendor like “the B Team”
  * The chance to act as a code architect, not just implement tickets
  * Exposure to a wide variety of industries and modern challenges
  * Me as your personal champion and advocate

Feel free to submit, even if you already did in the past.

We’re currently especially seeking:

Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)

Tier 3 roles are typically 5-10 years experience with $150-$180K total comp.

Tier 4 roles are 11-20 years experience, $215-$260K total comp

(Higher tiers exist, and we always welcome exceptional applications.)

Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.

Psiphon | iOS / Flutter Developer | Toronto (Hybrid) | Full-time

Psiphon is a VPN app used by millions of people to access the open internet in regions where it's restricted. Small team, software that matters.

We're building the next-gen client app in Flutter (iOS, Android, macOS, Windows) and need someone who can work across both iOS native and Flutter. Split is roughly 65% Flutter, 35% iOS native (Swift, StoreKit, entitlements, network extensions). You'll have mentorship from a senior iOS specialist for the deeper networking work.

Day to day: Feature development in Flutter, iOS platform integration (subscriptions, permissions, App Store), and occasionally going deep into network extensions and packet tunnel providers. Small team (~3-4 core devs), high ownership, low ceremony.

Looking for: Strong Swift experience beyond just UIKit/SwiftUI app dev, comfort with the iOS ecosystem (App Store process, provisioning, StoreKit), and willingness to context-switch between Swift and Dart in the same day. Flutter experience is a strong plus but not required if you pick up frameworks quickly.

MintMCP | Founding Engineer / Founding GTM | SF Bay Area (ONSITE)

MintMCP helps enterprises safely roll out agents to the entire organization (e.g, governance around MCP tools and agents like Claude Code / Codex / Cowork). We're building an MCP gateway with abstractions useful for 1) preventing agents from doing the unintentionally bad things you hear about every week without constraining them to be useless, 2) getting the rest of your teams and organizations to adopt them with minimal friction.

We're a small team of humans with dozens of agents: our company operates on the infrastructure we build for enterprises. We're looking for agent-forward engineers and GTM folks to help solve scaling problems, maintain the highest standards for security, make agents and MCPs usable and useful.

If you have experience in infra, security, and agents, and believe MCP, while not perfect, will evolve to become critical AI infrastructure, you might find the problems we're working on exciting!
