About The Position

Joby is looking for a software engineer with experience in electronics manufacturing and software development. Ideal candidates would contain both strong Python skills, electronics test equipment experience, and a firm understanding of the software/hardware interface. As a Senior Software Engineer for Test Infrastructure, you will develop software that enables the automation of electronics manufacturing tests in an aerospace production environment. You will manage a Python monorepo of microservices that spans test-execution services, hardware-in-the-loop (HIL) integrations, and CI/release tooling. Beyond code, you are expected to drive technical strategy and cross-team collaboration, turning ambiguous test requirements into a deterministic, automated reality.

Requirements

University degree in computer science, computer engineering or electrical engineering and 7+ years full time industry experience. An advanced degree and 5+ year of practical experience will also be considered.
Experience operating electronics test equipment (multimeters, power supplies, data acquisition devices).
Experience with networking, Modbus, I2C, and SCPI/VISA protocols and writing drivers for electronics test equipment.
Expertise in Python, specifically with asyncio for high-concurrency hardware control and an exposure to other languages such as: C++, C, Go, SQL.
Demonstrable experience in software development for production test equipment in a manufacturing environment.
Experience designing and implementing test strategies to assess the reliability of automation frameworks and libraries.
Mature understanding of Continuous Integration, Continuous Development (CI/CD) and DevOps tools.
Ability to work closely with the software development team, and teams in other domains, gathering requirements and feedback.

Nice To Haves

Experience building full-stack applications, including efficient web-based UIs and robust backend services using FastAPI and SQL.
Positive attitude and self-motivated work ethic with an openness to feedback.
Ability to work effectively as a team member in a geographically distributed team.
Willingness to be flexible and learn new technologies.
Ability to adjust quickly in a fast-paced environment.
Provide mentorship and technical guidance to the team, promoting high engineering standards through constructive code reviews and a collaborative, teaching-oriented approach to problem-solving.

Responsibilities

Build unique new test stations while providing high-tier support for existing stations, ensuring the production line remains deterministic and FAA-compliant.
Design and maintain Python test software and HIL (Hardware-in-the-Loop) infrastructure that gates the production and certification of Joby’s avionics systems.
Drive cross-functional discussions with software, hardware, and manufacturing engineers to translate complex manual acceptance procedures into reliable, fully automated software.
Maintain database schemas and ELT pipelines to store mission-critical test results for downstream aerospace analytics.
Full-Stack delivery of efficient UIs and robust backend services within an Agile/Sprint environment, deploying via CI/CD pipelines.
Understanding of networking fundamentals (TCP/IP, UDP, Routing) to design robust communication paths between test stations and aircraft hardware, ensuring low-latency and reliable data transport.
Build async Python services and hand-rolled drivers to interface with test equipment via a deep stack of protocols, including gRPC, WebSockets, Modbus TCP, and SCPI/VISA.
