SDET - Senior Software Developer Engineer in Test (SDET) Controls

About Standard Bots Standard Bot’s mission is to significantly lower the barrier to entry to real-world automation, bringing the power of bits to the world of atoms and unlocking productivity for entire new industries and users. Our user facing applications and APIs unlock the power of automation for entire new use cases. A relentless focus on simplicity and ease of use brings the revolutionary potential of robotic automation to new users and industries. Notes: This role will be required to come into our Glen Cove robotics factory 5 days/week What You'll Do You write the code that proves our controls and industrial-integration layer works. You're a developer first, but your domain is the seam where our robots meet the factory floor: PLCs, fieldbus protocols, I/O, and safety systems. You build the automated test suites, hardware-in-the-loop rigs, and PLC/protocol simulators that let us validate controls behavior without waiting on a physical cell, and you validate integrations in real time alongside the engineers building them. Responsibilities Build and own automated test suites and hardware-in-the-loop infrastructure for the controls and industrial-integration (PLC, HMI, fieldbus, I/O). Exercise industrial communication protocols in code: Modbus TCP/RTU, EtherNet/IP, EtherCAT, PROFINET, along with digital/analog I/O behavior. Build SW-based simulators and mocks for PLCs, fieldbus devices, conveyors, grippers, and safety hardware so controls testing isn't gated on physical equipment. Fold safety-system integration (e-stops, safety PLCs, light curtains) into automated release validation against industrial safety standards. Validate integrations in real time during the sprint, partnering tightly with software and applications engineers so defects are solved as they appear. Hand off maintainable test code and fixtures to Systems Test Engineers and Technicians, and review designs and PRs for testability and protocol compliance. Skills You'll Bring Strong Software Engineering: 4+ years (or strong equivalent) writing production-quality code daily in Python, C/C++, or TypeScript, with deep test-automation and CI/CD experience (Playwright, pytest, or similar). Controls & Industrial Automation: Hands-on background with PLC programming and industrial communication protocols (Modbus TCP/RTU, EtherNet/IP, EtherCAT, PROFINET) and digital/analog I/O. Electrical Fundamentals: Reads electrical schematics, comfortable with signal types (24V digital I/O, 4–20mA analog) and test equipment (multimeters, etc.), and can build and wire test fixtures and PLC cabinets. Systems Thinking: Comfortable debugging networked, distributed, and real-time systems across the software/hardware boundary. Impact Driven: You value simplicity, reliability, and velocity, and would rather prevent a bug than file one. Who You Are A developer with a controls or industrial-automation background who wants to apply strong software skills to robotics quality at the hardware seam — equally at home in a codebase and in front of a PLC cabinet. Nice To Have Allen-Bradley, Siemens, or Beckhoff PLC platforms; structured text ROS2, Docker, or robotics software stacks Hardware-in-the-loop or system-level test automation at scale Industrial safety standards (ISO 13849, ANSI/RIA 15.06) Compensation and Benefits: The salary range for this role is $110,000 to $150,000, depending on experience. We are open to a variety of seniority levels for this role and will build compensation packages that are commensurate with seniority and skill level. Base salary is just one part of the overall compensation at Standard Bots. All Full-Time Employees are eligible for Employee Stock Options. We also offer a package of benefits including paid time off, medical/dental/vision insurance, life insurance, disability insurance, and 401(k) to regular full-time employees.
