About the role

You will write production code that spans from device-level firmware interfaces up through orchestration software that coordinates the electrical, fluidic, and mechanical subsystems of a complex instrument.
This is a hands-on engineering role for someone who likes working close to the hardware, enjoys making messy real-world systems behave predictably, and takes pride in clean, well-tested code.
You will work closely with hardware, firmware, algorithm, and application engineers to take instrument subsystems from prototype to production.

Build Python applications and services that orchestrate, monitor, and expose instrument behavior
Develop and maintain device drivers, hardware abstraction layers, and communication interfaces (serial, USB, Ethernet, CAN, SPI, I2C)
Design and implement the software that coordinates electrical, fluidic, and mechanical subsystems into a working instrument
Build state machines and control loops that move the system through complex, multi-step protocols reliably
Develop and deploy on Linux - both desktop and embedded
Build and maintain Docker images and containerized workflows for development, testing, and deployment
Manage build environments, dependencies, and reproducibility across developer machines and target hardware
Build small, sharp tools that make the team faster - not large frameworks that slow them down
Experience building multi-component orchestration software for systems that combine electrical, fluidic, and mechanical subsystems (instruments, lab automation, robotics, manufacturing equipment, or similar)
The orchestration software is something other engineers want to build on - not something they work around

Hands-on experience with embedded development - talking to real hardware, working with constrained environments, and dealing with the failure modes that come with both
Hands-on experience with application development - services, APIs, user-facing tools, or orchestration software
Experience with CI/CD pipelines and build systems (CMake, Make, or similar)

Solid git fundamentals and good code hygiene - clear commits, readable diffs, useful tests, careful reviews
Comfortable with Docker and containerized development and deployment workflows
Experience designing state machines or control software for multi-step physical protocols
Comfort working alongside hardware, firmware, and mechanical engineers - and translating their constraints into software
Background in scientific instrumentation, biosensor platforms, lab automation, or medical devices
Experience with real-time or near-real-time control software
Familiarity with common embedded interfaces and protocols (Modbus, CANopen, EtherCAT, gRPC, MQTT, etc.)
Experience in regulated development environments (FDA, ISO, or similar)
Instrument subsystems behave predictably, recover gracefully, and are debuggable when they don't
Code you ship is reliable enough that the team trusts it, and clear enough that they can extend it without paging you
When a hard, cross-domain bug shows up, you are one of the people the team is glad to have on it
Work in a dynamic, collaborative environment where innovation and scientific rigor are deeply valued

Competitive compensation and equity package, comprehensive benefits, and flexibility to support work-life integration

We are a startup building complex, performance-critical software and hardware systems at the intersection of instrumentation, algorithms, and data.
We are looking for a Senior Software Engineer who is equally comfortable writing low-level C/C++ for embedded targets and building higher-level Python applications that tie a system together.
