HIL Test Engineer - System Test

Who we are

The company is reimagining what public transit can be. We believe that mobility is the gateway to opportunity—connecting people to housing, education, employment, commerce, and care. By making transportation more accessible, affordable, and sustainable, we empower communities to thrive and unlock economic and social prosperity.

Our mission is to revolutionize transit with a solution that delivers high capacity, exceptional user experiences, unmatched affordability, and minimal environmental impact.

The company system is a groundbreaking network of carbon-neutral, interconnected transit pathways powered by standardized autonomous vehicles on dedicated roadways. Operating 24/7 with on-demand access, it offers personalized and efficient mobility—without the burden of heavy upfront infrastructure costs or ongoing taxpayer subsidies.

With the company, we’re building more than a transportation system; we’re creating a future where everyone, everywhere, has the freedom to move.

Meet the team

At the company, the Test Engineering team is responsible for proving that our integrated autonomous transit system is safe, reliable, and ready for real-world operation.

We work across autonomy, vehicle hardware, embedded software, systems engineering, safety, infrastructure, operations, quality, and deployment teams. Our work spans simulation, software-based test environments, Hardware-in-the-Loop (HIL) testing, lab testing, vehicle testing, test-track operations, and project-site commissioning.

This role focuses on Hardware-in-the-Loop (HIL) testing and the test environments that allow the company to exercise real controllers, software, networks, interfaces, and failure modes before they reach vehicles, the test track, or customer sites.

Roles Overview

We are seeking a System Test Engineer who can build, operate, and improve Hardware-in-the-Loop (HIL) test capabilities for a complex autonomous transit system.

This role is ideal for someone who is comfortable at the boundary between test engineering, embedded systems, controls, software, hardware interfaces, automation, and data analysis. You will help ensure that system behavior, safety functions, regressions, and edge cases can be tested earlier, more often, and more repeatedly through high-quality HIL environments.

You will develop HIL test procedures, automate regression tests, manage test configurations and data, analyze results, and improve the benches, simulators, harnesses, dashboards, and workflows that make system testing more scalable.

We are open to candidates across a range of experience levels, from strong mid-level engineers through staff-level technical leaders. Scope and title will be calibrated based on experience. More senior candidates will be expected to own larger HIL capabilities, improve test architecture and process, mentor others, and represent test evidence in readiness and release discussions.

This role will include hands-on work with test benches, controllers, networks, lab equipment, vehicles, and the company test facilities. Some travel or on-site presence should be expected for integration campaigns, test environment bring-up, and major release demonstrations.

Responsibilities

• Develop and execute Hardware-in-the-Loop (HIL) test plans, procedures, and automated test cases for integrated autonomous transit behavior.

• Translate requirements, operational scenarios, safety needs, and regression concerns into repeatable HIL tests with clear pass/fail criteria.

• Expand automated regression coverage so system behavior can be tested earlier and more frequently before vehicle or track testing.

• Execute and troubleshoot tests involving embedded controllers, vehicle subsystems, autonomy interfaces, communications, diagnostics, fault handling, and degraded-mode behavior.

• Analyze logs, telemetry, traces, dashboards, and bench observations to determine test outcomes, identify anomalies, and support root-cause analysis.

• Track HIL test failures from discovery through closure, including issue classification, impact assessment, regression scope, and verification of fixes.

• Improve test automation, simulators, tooling, dashboards, data pipelines, and reporting workflows to increase coverage, repeatability, execution speed, and confidence in test results.

• Support readiness reviews by preparing evidence on test environment readiness, configuration status, prerequisite completion, approved procedures, safety controls, and open issue disposition.

• Collaborate closely with embedded software, autonomy, vehicle engineering, systems engineering, safety, quality, operations, and deployment teams.

• Build lightweight tools, scripts, widgets, dashboards, or utilities when existing tools are not sufficient for the test work.

Ideal Candidate

• Has strong HIL instincts: knows how to combine real hardware, simulated interfaces, automation, instrumentation, and data capture into a trustworthy test environment.

• Can turn ambiguity into clarity: drive vague, high-level needs into concrete bench tests, automated checks, pass/fail criteria, and release evidence.

• Thinks in interfaces and failure modes: understands how software, controllers, networks, sensors, actuators, timing, configuration, and operating assumptions interact.

• Has strong follow-through: closes the last 5% by cleaning up evidence, resolving ambiguity, documenting decisions, and leaving work in a reusable state.

• Communicates clearly and proactively: chooses the right medium and level of detail for the audience, creates durable artifacts when needed, and helps cross-functional teams align around complex technical problems.

• Is hands-on and data-driven: comfortable in the lab, with hardware, in logs, in Python and C++, and in issue-tracking and requirements tools.

• Enjoys building practical tools and improving test infrastructure when that makes the test program more effective.

• Learns quickly and willingly adapts to new tools, workflows, and technical domains when the work requires it.

Knowledge, Skills and Abilities

Required

• Bachelor’s degree in Engineering, Computer Science, Robotics, Aerospace, Mechanical Engineering, Electrical Engineering, Systems Engineering, or a related technical field.

• 4+ years of experience in system test, Hardware-in-the-Loop (HIL) testing, embedded systems test, systems integration, product validation, autonomous systems, robotics, transportation, aerospace, automotive, medical devices, industrial automation, or other complex hardware/software systems.

• Experience developing or executing integration-level or system-level tests, including scenario design, test procedures, acceptance criteria, execution, analysis, and reporting.

• Experience working with complex electromechanical or cyber-physical systems that combine software, controls, sensors, networks, hardware, safety constraints, and operational procedures.

• Ability to analyze logs, telemetry, traces, test data, and system behavior using tools such as Python, dashboards, log viewers, notebooks, or equivalent analysis environments.

• Demonstrated ability to collaborate across multidisciplinary teams and communicate technical risk, test outcomes, and blockers clearly.

Preferred

• Hands-on experience developing tests for Hardware-in-the-Loop (HIL) benches, test harnesses, simulators, automated regression frameworks, or continuous integration-driven test execution.

• Experience with embedded systems, controller testing, vehicle networks, diagnostics, fault injection, real-time systems, or hardware/software integration.

• Ability to read, modify, or write C/C++ for embedded systems, test harnesses, or low-level debugging.

• Experience with test automation, data analysis, dashboards, report generation, or practical engineering tools that made a test program more effective.

• Experience with autonomous vehicles, automated transit systems, railway systems, robotics, aerospace, automotive Advanced Driver Assistance Systems, or other safety-critical mobility platforms.

• Experience with requirements, issue-tracking, or lifecycle tools such as Jama, DOORS, Polarion, Systems Modeling Language, Jira, GitHub, or equivalent tools.
