Test Development information

What is test development?

Test development is the process of designing, creating, and validating assessment tools such as exams, quizzes, or standardized tests. This process involves defining the purpose of the test, constructing test items, reviewing them for quality, and conducting statistical analyses to ensure reliability and validity. Test developers often work in educational, psychological, or professional certification contexts to measure knowledge, skills, or abilities accurately. The goal is to create fair, unbiased tests that provide meaningful information about the test takers.

What are the key skills and qualifications needed to thrive in test development?

To excel in Test Development, strong analytical skills, a background in educational measurement or psychometrics, and a relevant degree such as education, psychology, or statistics are essential. Familiarity with test authoring platforms, statistical analysis software (like SPSS or R), and knowledge of standards such as item response theory (IRT) are typically required. Attention to detail, critical thinking, and effective collaboration are key soft skills for designing fair and valid assessments. These skills ensure the creation of reliable, unbiased, and meaningful tests that accurately measure intended outcomes.

What are some common challenges faced in a test development role, and how can they be addressed?

One common challenge in Test Development is ensuring that assessments are both valid and reliable while meeting tight deadlines. Balancing subject matter expertise with psychometric principles can also be demanding, particularly when collaborating with content experts and statisticians. Clear communication, careful project planning, and continuous professional development help address these challenges. Additionally, staying updated on assessment standards and using feedback from pilot tests can greatly improve test quality.

What is the difference between Test Development vs Test Analysis?

AspectTest DevelopmentTest Analysis
Primary FocusDesigning and creating tests and assessmentsInterpreting test results and analyzing data
Required SkillsCurriculum design, item writing, psychometricsData analysis, statistical skills, reporting
Work EnvironmentEducational institutions, testing companiesResearch organizations, educational settings
CertificationsPsychometric certifications often preferredData analysis or psychometric certifications

Test Development focuses on creating assessments, while Test Analysis involves interpreting results and analyzing data. Both roles are essential in the testing industry, often working together to ensure valid and reliable assessments.

Key responsibilities

  • Develop and own test systems for NEO's electronics and robotic subassemblies from design release through high-volume production.

  • Build and maintain functional and end-of-line test stations, including operator-facing test applications with clear pass/fail criteria and traceability.

  • Improve test station performance, troubleshoot failures, and connect test results and logs into data systems to support quality and production insights.

Job description

Role Name: Test Engineer/ Senior Test Engineer
Department: Manufacturing
Location: San Carlos
About 1X
We're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it's not.
To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you're inspired by this, you'll thrive here. We've been at this since 2014 and we're at the point where the hard problems are behind us and the hard work is in front of us.
NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We're not demoing it - we're shipping it. We're excited to meet you, if this excites you.
If you've spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We're scaling, we're hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.
About the Team:
Test Engineering builds the systems that decide whether NEO hardware is ready to ship. We sit at the intersection of R&D, design, engineering and production. Developing the functional and end-of-line test stations that catch defects early, gate quality on the line, and turn production data into engineering action. As NEO scales into high-volume production, our work is what lets 1X grow without compromising quality.
Your Charter: Develop and own test systems for NEO's electronics and robotic subassemblies as they move from design release into high-volume production. This is a hands-on role spanning software, electronics, firmware, fixtures, and production operations - you'll own stations from requirements through deployment and long-term support. You won't just run tests; you'll build the systems that decide whether robot hardware ships.
Key Outcomes:
  • Own functional and end-of-line test stations for robot subassemblies (feet, head, battery, hands, arms, power boards) across their full lifecycle - requirements through deployment, maintenance, and corrective action.
  • Ship operator-facing test apps with guided flows, clear pass/fail verdicts, robust error handling, and unit-level traceability.
  • Improve station uptime, cycle time, test coverage, data quality, and deployment repeatability as production scales.
  • Reduce escaped defects by reproducing and resolving failures across hardware, firmware, software, instruments, fixtures, and process - driving corrective action when stations or products fail.
  • Connect results, serial numbers, board IDs, and logs into test-data systems so production data becomes actionable insight.

Key Competencies:
  • Strong software development in Python and C++ for test applications, instrument automation, and station infrastructure.
  • Systems thinking across electronics, firmware, software, robotics hardware, fixtures, and production processes.
  • Root-cause debugging grounded in data, logs, measurement, and controlled experimentation.
  • Hands-on hardware ability: reading schematics, probing boards, debugging signals, and using bench instrumentation.
  • Bias to action: makes decisions under production pressure, executes, and owns the result.

Minimum Requirements:
  • Background in Electrical Engineering, Computer Engineering, Computer Science, Robotics, or equivalent practical experience.
  • Proficiency in Python and/or C++, with willingness to work in both.
  • Ability to read schematics and debug electronics at the board or subsystem level.
  • Exposure to embedded systems, microcontrollers, or protocols such as CAN, SPI, I2C, UART, Ethernet, or EtherCAT.
  • Hands-on experience with bench instrumentation (oscilloscopes, logic analyzers, multimeters, programmable power supplies).

Preferred Skills:
  • Building production test stations, end-of-line testers, hardware-in-the-loop systems, or test infrastructure.
  • Robotics, electromechanical systems, motor controllers, sensors, actuators, batteries, embedded Linux, or real-time systems.
  • Deploying and maintaining software across multiple production PCs or factory stations.
  • Test-data pipelines, traceability, dashboards, WATS, MES, SQL, Splunk, or similar.
  • Linux, Docker, Git, CI/CD, Bazel, remote deployment, or automated station management.
  • AI-assisted development tools for faster software development, debugging, documentation, or fixture bring-up.

What does a successful 1X Team Member look like:
Team members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it's the one thing you can't get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect.
Compensation Range:
$148,000 - $181,000 + Equity
Benefits:
  • Comprehensive medical, dental, and vision coverage
  • Generous paid time off, company holidays, and parental leave
  • 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
  • Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
  • Commuter benefits (transit and parking)
  • Short-term and long-term disability, and life insurance
  • Employee Assistance Program (EAP) for mental health, financial, and personal support
  • Onsite snacks and catered lunches
