Until is a moonshot company building a “pause button” for biology. Our near‑term focus is organ‑scale reversible cryopreservation: preserving donated organs at subzero temperatures without ice formation, then rewarming them uniformly for transplant. By solving this grand challenge, we're laying the foundation for whole‑body reversible cryopreservation, giving patients a bridge to future cures. To achieve our goal, we are assembling an interdisciplinary team to develop perfusion systems, cryoprotectant formulations, and vitrification and rewarming hardware. We envision a future where no transplantable organ is lost to logistics, and no terminal diagnosis is final because patients can safely wait for future medicine to arrive. About the Role One of the key outstanding challenges in the field has been the rewarming problem: how do we rapidly and uniformly rewarm large samples to press play on cryopreserved biology? One of the key ingredients is building N‑of‑1 electrical systems. Doing so requires a fast paced, scrappy team of electrical engineers and physicists who want to make technology indistinguishable from magic. About You Track record of exceptional engineering abilities Deep understanding of analog circuit and electromagnetics fundamentals Experience designing, simulating, and building high frequency circuits Desire to join a small, fast paced team on an excellent adventure Preferred Qualifications Experience working at a startup 3+ years relevant experience/graduate degree in electrical engineering Experience with high voltage systems Experience with induction heater design Experience with HF PCB bringup Experience with mixed signal circuit simulation Benefits Opportunity for outsized impact creating the future as an early team member Generous medical, dental and vision insurance coverage Flexible time off and paid holidays Competitive compensation package, including salary and equity Access to a 401(k) retirement savings plan FSA and commuter benefits Subsidized lunch daily Salary Range: $120,000 - $200,000 a year.

As an equal opportunity employer, Until is committed to providing employment opportunities to all individuals. All applicants for positions at Until will be treated without regard to race, color, ethnicity, religion, sex, gender, gender identity and expression, sexual orientation, national origin, disability, age, marital status, veteran status, pregnancy, or any other basis prohibited by applicable law. #J-18808-Ljbffr

Founding Hardware Engineer (Stealth Robotics Startup) On-Site • San Francisco, CA About Us We're a tiny, fast-moving team building autonomous systems for heavy industrial machines. We retrofit existing equipment with a plug-and-play autonomy kit that taps directly into machine controls and layers on a full perception + connectivity stack: multi-sensor vision, LiDAR, high-precision GNSS, IMU, and a low-latency tele-operation network. In just a few months, we've gone from first prototype to real machines operating on active job sites, with early recurring revenue and a growing pipeline of paid pilots. We're backed by top-tier early-stage investors along with a group of founder-operators who know what it takes to build in the real world. Our founding team has built and shipped hardware, software, and robotics systems before. We thrive where physical machinery, harsh environments, and rapid iteration collide. Why Join Us You want to work on problems that actually matter - fixing how the world builds things. Construction is the backbone of civilization, and it's currently broken. We're here to change that. You don't want a cushy robotics lab job. You want to build robots in the mud, on real sites, under real constraints. You'd rather spend a week living out of a dusty RV next to a machine you're debugging than polishing a slide deck. You want to see your designs move 20-50 tons of real hardware. You want to feel the stakes. You want teammates who operate at founder-level intensity and ownership. About You You're a hacker at heart - the kind of person who gets a prototype working before most people finish their planning doc. You've built something from scratch: a company, a product, a robot, a system - success not required, agency absolutely required. You work extremely hard, laugh often, and don't mind chaos. You prefer “figure it out now” to “wait for perfect requirements.” What You'll Own As a founding Hardware / Mechatronics Engineer, you'll design and build the core systems that enable remote operation, sensing, and autonomy assistance on industrial machines. You'll work across mechanical, electrical, and embedded disciplines, often all in the same day. System Design & Prototyping Architect and build tele-operation hardware systems, including power, compute, and control modules for machine retrofits. Sensor Integration Integrate and calibrate cameras, LiDAR, radar, GNSS, IMUs, and other sensors using interfaces like GMSL, CAN, and Ethernet. Electrical & Mechanical Integration Design robust wiring harnesses, brackets, mounts, and enclosures that survive real-world abuse. Communication Interfaces Implement and validate CAN, LIN, J1939, Serial, and Ethernet connections with both existing ECUs and custom control hardware. Manufacturing & DFM Work with vendors to bring designs from scrappy prototypes to reliable production, including DFM, testing, and validation. Testing & Validation Lead machine bring-up, HIL testing, and on-site debugging alongside software and autonomy engineers. Documentation & Design Produce schematics, harness drawings, CAD models, assembly docs, and anything else needed to build and scale the hardware. Compensation & Support Base: ~$200-300k Equity: ~1-3% Full health/dental/vision, relocation + visa support, downtown SF workspace with full electronics/mech prototyping tools, 401(k), high-spec laptop, and budget for any gear you need.

Please read more about our culture here ******************************* Who should join: You like working in person with a team in San Francisco. You deeply believe that this is the most important mission for humanity and needs to happen yesterday. You are highly technical - regardless of the role you are in. We are building technology; you need to understand technology well. You care about aesthetics and design inside out. If it's not the best product ever, it bothers you, and you need to “fix” it. You don't need someone to motivate you; you get things done. Why We Are Hiring for This Role: Own the end‑to‑end design of the vehicle electrical system, from power distribution to harness integration. Develop schematics, harness drawings, and PCB‑level designs for subsystem interconnects. Lead bench bring‑up of sensors, actuators, and compute subsystems prior to vehicle integration. Define and execute electrical validation tests (continuity, insulation, load testing, EMI checks). Work closely with Mechanical Engineering on packaging and routing of harnesses. Support system bring‑up during assembly, troubleshoot electrical issues, and drive root‑cause analysis. Collaborate with Embedded/Software to ensure clean power, comms, and integration for all subsystems. What Kind of Person We Are Looking For: Experience with sensors, actuators, and communication buses (CAN, Ethernet). 5-8+ years of experience in vehicle electrical systems, robotics, or related embedded hardware projects. Strong background in power distribution, harnessing, and PCB‑level design. Hands‑on experience debugging hardware in lab/bench settings. Familiarity with grounding, shielding, and safety practices for LV and HV systems. Comfortable working cross‑functionally and hands‑on in fast‑paced prototyping environments. BS/MS in Electrical Engineering or related field. We provide market standard benefits (health, vision, dental, 401k, etc.). Join us for the culture and the mission, not for the benefits. The annual compensation is expected to be between $180,000 - $1,000,000. Exact compensation may vary based on skills, experience, and location. #J-18808-Ljbffr
