Apex Dental Partners | Full-Stack Developer | Dallas, TX | REMOTE (US) or HYBRID | Full-time | apexdp.com

We're a Dental Support Organization running 65 practices across eight states. Dentistry doesn't sound like a technical job, but the platform behind it is: we've built our own operations system (Rails 8 + React, Electron, Go, and C#/.NET against OpenDental, all on AWS) and we're pushing hard on automation and AI to make the practices run better.

The team is small and developers own problems end-to-end. You'll figure out why a billing workflow breaks down, design the fix, ship it, and hear from the office manager who uses it the next week. Recent work includes an AI-first metrics layer that answers operational questions in chat, automated patient scheduling and communication, insurance verification scraping, and a live PMS integration across every practice. The domain is wide (clinical workflows, payroll, patient comms, revenue cycle) and there's a lot of novel work left once you learn the business. Big emphasis placed on being able to sit down with non-engineering team members and understand their workflows and build software to make it better.

Good fit if you want a stable company, a small team, broad latitude, and work that visibly matters to the people using it. We're actively building new features, not just maintaining what exists, so there's a healthy mix of greenfield work and improving a platform that's already in daily use by our nearly 1,000 employees.

Must reside in the US and be authorized to work in the US without sponsorship.

MIRA | Firmware Engineer | San Francisco, CA | ONSITE | Full-time

MIRA builds lightweight AI glasses that act as a second brain: they remember conversations, answer questions in under a second, translate 60+ languages, and surface useful context through a private display. We recently sold out and shipped our first batch, and have raised $6.4M from General Catalyst, Naval Ravikant, Pillar VC, and others.

We're hiring a firmware engineer to work close to the hardware across C/C++ or Rust, RTOS, BLE, embedded Linux, microcontrollers, sensors and audio pipelines, power optimization, device communication, and low-level debugging. We're looking for 3+ years of software or firmware engineering experience and a track record of shipping complex technical products end-to-end. Consumer hardware and early-stage startup experience are strong pluses.

This is a full-time, in-person role in San Francisco. We can't provide current or future U.S. visa sponsorship.

Tecuity | Senior Software Engineer I | Hyde Park, UT (ONSITE preferred; will consider candidates who can commute in 1-2x/month) | Full-time | $90k-$135k

Tecuity has spent 20+ years building software for Secretary of State offices — state government agencies handling business filings and public records. Real filing deadlines, statutory requirements, and citizens who depend on the system working.

We're hiring a Senior Software Engineer I to own features end-to-end on a mature, multi-tenant .NET platform, typically supporting more than one client implementation at a time, each with its own database and release calendar.

Stack: C# / .NET 8 & .NET 10, ASP.NET Core, Web API, Entity Framework Core, MS SQL Server (heavy stored-procedure work), React + Redux front end, Git/PR workflow, Azure DevOps CI/CD.

AI-assisted development (Claude Code) is a standard, daily part of our engineers' workflow here, not a pilot program — you'll be expected to use it well and verify its output rather than just accept it.

Looking for 6+ years professional experience in C#/.NET and SQL Server. Government, regulated, or compliance-driven software experience is a plus.

Ideally we're looking for candidates who can work onsite from our Hyde Park, UT office, but we're open to Utah or Idaho candidates who can commute in once or twice a month for the right fit.

Email hr@tecuity.com with a bit about your background and a resume or for more information. See the full job posting at tecuity.com/careers

Robotics and AI Institute | Software Engineering Intern | ONSITE (Zürich, Switzerland) | Internship | No visa sponsorship

We're hiring some robotics systems software focused interns in our Zürich office. We're specifically looking for late stage masters students with strong software engineering fundamentals and some skills in turning math into performant code. We have two tracks available, either offline training infrastructure for RL (physics simulation, gaussian splatting, RL algo implementation) or on-robot deployment (online inference, fast C++).

The software team in Zürich is involved in building the tools that accelerate research, while having a close connection to what the researchers are doing.

We're looking for people who already have the right to work in Switzerland. That means Swiss/EU/EFTA citizens, or those with a work permit in Switzerland already.

Axo | Lead Founding Engineer | Sugar Land / Houston, TX (HYBRID) | Full-time | $120k–$160k + Founding Equity

Want to help out healthcare providers? Clinicians using our software are already saving hours a day and loving their job again. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.

Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. You’ll join as a founding engineer working directly with myself (former Google SWE) and my co-founder (one of the US's best known O&P clinicians), and small engineering team we want to grow.

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

Founded in 2019, we're an NSF- and investor-backed startup in Orange County, CA, with a team of 6 PhDs in computer vision.

We're hiring a Machine Learning Engineer to help push the frontier of AI for watermarking, steganography, and media provenance. You'll take state-of-the-art steganography models and own their journey to production — optimizing and deploying them on desktop and cloud platforms, serving as the link between research and customer-facing products.

Responsibilities: productionize novel steganography models, build inference pipelines, integrate models into cloud platforms, benchmark performance, and turn research into maintainable production code.

Required: PyTorch, ONNX export, experience deploying deep learning models to the cloud, Python and C/C++, strong cross-team communication.

Bonus: background in steganography/watermarking/media provenance, video/image codecs, MLOps tooling, CV/ML publications or open-source contributions.
