Senior System Test Engineer

Company Description

Pixels on Target builds high-performance thermal imaging systems that push the limits of what’s possible at the edge. We combine advanced sensing, embedded systems, and AI/ML to deliver real-time intelligence in the most constrained environments. Our focus is speed, performance, and delivering systems that work—reliably—when it matters most.

Role Description

We’re looking for a hands-on Embedded System Test Engineer who owns system-level validation end-to-end. This is not a passive QA role—you will build the infrastructure, automation, and intelligence needed to validate complex embedded and AI-enabled systems at scale.

You will operate across hardware, firmware, software, and ML pipelines, ensuring everything integrates, performs, and ships fast. Expect to work in a fast-moving environment with evolving requirements and aggressive timelines.

Responsibilities

• Own system-level verification and validation across hardware, firmware, software, and AI/ML pipelines.
• Build automated test infrastructure from the ground up—design, implement, and scale test frameworks integrated into CI/CD.
• Drive full automation of regression, performance, and system-level testing with minimal manual intervention.
• Integrate AI/ML into test workflows (failure prediction, anomaly detection, intelligent test selection, coverage optimization).
• Validate ML models at the edge—dataset handling, inference validation, accuracy/performance tradeoffs, and regression tracking.
• Break systems—identify integration issues across sensors, compute, firmware, and algorithms, and drive root cause to closure.
• Develop high-quality, repeatable test environments including hardware-in-the-loop (HIL) setups and data-driven validation pipelines.
• Define and enforce test strategy, coverage, and release criteria across programs.
• Embed testing directly into CI/CD pipelines—every commit validated, every regression caught early.
• Support rapid NPI cycles—bring-up, qualification, and production readiness under tight timelines.
• Work closely with engineering teams to iterate fast and eliminate bottlenecks in system validation.

Desired Skills and Experience

• 5+ years building and automating system-level testing for embedded systems.
• Strong Python and C/C++ skills—able to build tools, not just use them.
• Proven experience building CI/CD-integrated test systems (Jenkins, GitLab, Bitbucket, etc.).
• Experience validating AI/ML systems in production or embedded environments (model validation, datasets, inference behavior).
• Strong debugging skills across hardware/software boundaries—comfortable with scopes, analyzers, and low-level interfaces.
• Experience with embedded protocols (I2C, SPI, UART, USB) and system bring-up.
• Familiarity with RTOS-based systems and real-time constraints.
• Experience with HIL testing, automated lab setups, or production test systems is a strong plus.
• Bias for action—comfortable with ambiguity, able to execute without perfect specs.
• High ownership mindset—drives problems to closure, not just identifies them.
