We believe that the best solutions are built together, and we are looking for a key member to join our collaborative R&D team.
About the Role
We are seeking a highly motivated and skilled engineer to join our team in developing next-generation patient monitoring systems. This role is at the intersection of computer vision, signal processing, and high-performance software engineering. You will be responsible for building the core analytical engine that transforms raw depth-sensor video into actionable health information.
This is not a purely theoretical position. You will be hands-on, designing algorithms that are efficient enough for real-time applications and robust enough for real-world clinical use. You will write the production-level Python code that brings these algorithms to life on cutting-edge edge computing platforms.
If you are a problem-solver who thrives on analyzing complex sensor data and building tangible, high-performance systems, we want to hear from you.
Key Responsibilities
Develop and implement real-time computer vision algorithms in Python to detect, track, and analyze regions of interest from video data (specifically depth sensors).
Design and build signal processing pipelines to extract, filter, and interpret physiological movement data from sensor signals.
Optimize algorithms for performance to meet strict real-time processing requirements.
Deploy and validate analysis software on edge computing platforms with GPU acceleration (e.g., NVIDIA Jetson).
Collaborate in a multidisciplinary team to integrate your solutions into a complete monitoring product.
Rigorously test, debug, and document your code and algorithms.
Required Qualifications
Strong proficiency in Python and experience writing clean, efficient, and maintainable code.
Solid foundation in computer vision principles and hands-on experience with libraries like OpenCV.
Solid foundation in digital signal processing (e.g., filtering, time-series analysis, feature extraction) and experience with libraries like SciPy or NumPy.
B.S. or M.S. in Computer Science, Robotics, Electrical Engineering, Biomedical Engineering, or a related technical field.
Demonstrable experience in analyzing imaging or sensor data to solve complex problems.
Excellent problem-solving skills and the ability to work independently and as part of a team.
Preferred Skills (We'd love to see these)
Experience with high-performance edge computing platforms (e.g., NVIDIA Jetson).
Familiarity with GPU programming (e.g., CUDA, TensorRT) for accelerating algorithms.
A background in robotics, autonomous vehicles, or real-time analysis of sensor data (e.g., LiDAR, RADAR, IMU).
Experience with depth sensors, 3D data processing, or point cloud analysis.
Knowledge of machine learning or deep learning frameworks (e.g., PyTorch, TensorFlow) for vision or time-series tasks.
Familiarity with software development best practices (e.g., Git, unit testing, CI/CD).

Software Engineer
Software test engineer job in Fremont, CA
As a software engineer at General Medicine, you'll help build and scale a healthcare store that makes it delightfully simple to shop for any type of care. We provide upfront cash and insurance prices for virtual and in-person visits, prescriptions, labs, imaging, and more.
What we're looking for
We're looking for strong engineers to help us build a seamless and beautiful consumer healthcare product. We're looking for folks who will obsess over every detail of our patient experience, and also tackle the complex operational challenges of delivering care at scale. We are looking for engineers who care deeply about technical excellence but are also comfortable moving quickly - we are constantly navigating tradeoffs between engineering velocity and quality.
Our ideal candidate is hungry, high-agency, and aspires to be a generalist. Our engineers frequently write product requirements documents, write SQL to understand how features are performing, and own QA - no task is beneath us or outside of the scope of the role if it helps us to deliver a great product. We're looking for someone who can operate in an environment of significant ambiguity, and who is comfortable working closely with design, operations, and clinical stakeholders.
We don't expect you to have a healthcare background (though it's great if you do!). However, you should be excited by the prospect of digging into the messy complexities of the American healthcare system (integrating with EHRs, revenue cycle management, etc).
Qualifications
2+ years of experience building web apps as a full-stack engineer
Experience with modern infra tooling and programming languages. We currently use AWS, Ruby on Rails, and NextJS, and would expect you to have proficiency in a modern tech stack even if it isn't the one we are using.
Please note that this role is based in either our SF office (near Market and Spear St) or our Boston office (Central Square, Cambridge). We expect our team to work from the office least 3 days per week.
Why join us
We're an experienced team that has built a company in this space before, our product has clear product-market fit, and we've raised money from top investors.
We have an ambitious and distinctive vision for what can be built in consumer healthcare. We believe LLMs and price transparency legislation have opened up several massive opportunities.
If you're an ambitious and entrepreneurial software engineer and this resonates, please apply.
