We build kinetic sculptures that shouldn’t exist. A small team of designers and engineers, creating massive, data-driven installations that live in the world’s most iconic spaces.
This is for someone who’s looking for a totally different job. You want to work on seriously hard problems along a talented multidisciplinary team. Ready to jump both feet into new problem domains, figure out what needs to be done - and do it.
Here’s a behind-the-scenes of a large piece we did: https://youtu.be/Y-X82D1dBLc?si=Dj-5casrqoXP9wVy&t=228
The Tech & The Role:
You’ll be a senior voice on a tight team, touching every layer of the stack
- Systems/Backend: Managing Linux-based distributed systems that coordinate massive arrays of sensors and actuators. - Embedded/Firmware: Writing C/C++ for custom PCBs and motor controllers. - Languages: Primarily Python, JS, C, and C++. - Hard Problems: Real-time constraints, custom networking protocols, and high-reliability systems that have to run 24/7 in public spaces. We're looking for: - 10+ years of experience. We need a "tinkerer" who understands math/physics and isn't afraid to poke at hardware. - Someone who thrives on "mission-critical" pressure. When a sculpture goes up in a public plaza, it has to work. - Mentorship-minded. You’ll help shape the software culture as we grow. We aren't a typical art studio, our tech is state-of-the-art. You’ll work alongside ME's and EE's in our Brooklyn studio to build things experienced by millions. The role is primarily onsite in Brooklyn, but some flexibility can be discussed.Studio: https://breakfaststudio.com/

Innolitics builds AI/ML software for medical devices — the kind that detects ear infections, tracks metastatic cancer, and plans radiation therapy. 60+ FDA clearances. We need engineers who want their work to matter. We're a remote-only firm (since 2012) that does engineering, regulatory, and cybersecurity under one roof. Our team includes MDs, PhDs, and software engineers. Clients range from Series A startups to large device companies. We're hiring for three roles:
1. Physician-Scientist (MD/PhD) — Biostatistics & AI Software Development MD + PhD in biostatistics, bioinformatics, epidemiology, or a related quantitative field. You'll design biostatistical plans for AI validation studies (MRMC, standalone, prospective), build production-grade statistical software and data pipelines, write FDA-facing statistical sections, and analyze large clinical imaging datasets. Fluent in Python and/or R. This is not a pure research role — you'll ship code that gets FDA-cleared and deployed in clinics.
2. Senior Web/Mobile Medical Device Engineer 5+ years SWE experience. 3+ years each in web and mobile. Fluent in TypeScript and Python. You'll build medical device software and produce FDA-facing technical documentation. Cross-functional role bridging engineering and regulatory teams.
3. Medical Device Software Engineer 3+ years SWE experience. Fluent in Python, C++, or TypeScript. Heavier emphasis on software development initially; you'll grow into regulatory documentation work over time. All roles involve writing production code for medical devices, authoring documentation for FDA submissions, and working directly with clients. No prior medical device experience required — we'll teach you. Why engineers stay here:
Agentic AI tools (Claude Code, etc.) are part of our workflow. We treat them as a impact multiplier, not a threat. ~1 hour of meetings/week for ICs. Flexible hours. 2 hours every Wednesday dedicated to learning ("10x Time"). Healthcare-only revenue. No debt. Never had a layoff. We pay $300 for take-home exercises because your time has value.
Stack: Python, TypeScript, C++, R, Django, React, TensorFlow, PyTorch, scikit-learn, Qt, Terraform.

Proton VPN enables millions of people to connect securely and privately, even in places where the internet is restricted or unreliable. Delivering that experience means our service must perform flawlessly under highly variable, real-world conditions.
We are looking for a Senior Performance Engineer to lead our efforts in making Proton VPN the fastest, most resilient, and most reliable VPN service in the world.
You will define and drive the measurement, analysis, and optimization of Proton VPN’s end-to-end performance, across clients, platforms, and global infrastructure. You’ll help ensure that every connection is fast, stable, and private, regardless of where the user is or what network they’re on.

At SkySafe we build drone detection and tracking at scale.
I am looking for a Wireless Communications Engineer with SDR expertise to join my team - I'm the hiring manager.
I need someone with a very strong background in signal theory and experience building software wireless modems. You will spend time learning about new systems from our reverse engineers (no RE experience required!), implementing both open and recovered specifications, and refactoring existing modems code to improve it in both theory (ie - what is the algorithmic state of the art for demodulating xyz thing) and practice (ie - how much memory bandwidth and CPU are you using where). As such, I'm looking for someone with true software modem experience; while DSP, FPGA, and generated code experience are useful and relevant, you'll need to be able to read and write C++ directly.
I need someone who can come into the office in San Diego as needed to work with hardware, so this is a hybrid on-site role. This position requires access to technology which is controlled by US Export laws, so you also need to be an eligible US Person.
What we have to offer: $145-200k. Fun, small team dynamic. Work with experts in adjacent fields. Startup environment with good work-life balance and limited red tape. Rapid iteration and feedback in the wild. Good equipment at the office.

Fullstack Developers
You'll work across the JavaScript and TypeScript layer of our local AI stack. Depending on the project, you might build user-facing applications (mobile or desktop) or contribute to the platform layer that bridges our C++ inference engines with the app ecosystem. Either path puts you at the heart of making local AI usable: whether you're crafting polished product experiences or building the SDK and bindings that other developers rely on. This role suits engineers who thrive in a full-stack JS environment and want to be part of a system where AI runs privately, locally, and fast.

Product Engineer:
You'll own the vision and execution of local AI products, from roadmap to release. Half your time goes into code, the other half into alignment: defining what to build, why it matters, and how to ship it well. You'll lead a pod of engineers across the stack, ensuring that the power of on-device AI translates into products people actually want to use.
This role is for builders who care deeply about the end result: making local, private, and powerful AI accessible through thoughtfully designed products.

We’re hiring principal-level software engineers to join the former Affera team — now part of Medtronic — building next-generation cardiac electrophysiology (EP) mapping and ablation systems.
The Affera Mapping and Ablation System is designed to treat patients with cardiac arrhythmias through advanced mapping and integrated therapy delivery. The platform creates detailed, real-time visualizations of the heart’s electrical activity, enabling physicians to identify abnormal areas. Once identified, the system delivers targeted ablation energy to disrupt those signals and restore normal rhythm.
As part of Medtronic’s EP portfolio, we’re scaling and advancing this technology into the next generation of integrated mapping and generator systems.
We’re looking for Senior and Principal engineers with either:
- Desktop UI focus (Qt/QML or similar frameworks), or
- Core systems focus (C++/Python, real-time signals processing, ROS, Linux, hardware integration).
