Reliability and Test Engineer

Electronics Reliability & Component Qualification Engineer

The Reality of the Role

We don't build consumer tech or standard commercial electronics. Our hardware is deployed into the most brutal, high-consequence environments on the planet-operating miles beneath the earth's surface under crushing pressures and extreme temperatures exceeding 150°C to 200°C+.

When an asset is deployed downhole, our clients expect it to run flawlessly for decades without a single point of failure. If a component fails miles underground, pulling that tool back up can cost operators millions of pounds in rig downtime. Because of this, reliability isn't a box-checking exercise here; it is our primary product.

We are looking for an investigative, fiercely organized Electronics Reliability & Qualification Engineer to join our R&D hub. Your core mission is simple but incredibly high-stakes: prove our hardware can survive the impossible. When a semiconductor or component manufacturer makes a microscopic change to a part, or alters a silicon fabrication line, you are the final line of defense. You will have the ultimate responsibility to conceptualize, design, and execute rigorous stress-testing pipelines to back up our multi-decade performance guarantees with undeniable, clean, technical proof.

Core Responsibilities

Own Component Qualification: Act as the ultimate gatekeeper for all electronics entering our high-reliability ecosystems. When parts change or new materials are introduced, you will identify exactly what needs testing, why it needs testing, and how to build the test setup to prove its lifetime limits.

Execute Forensic Investigations: Track, review, and investigate complex product and component reliability issues. When an anomaly occurs, you will run failure analyses to diagnose the root cause-evaluating silicon degradation, solder fatigue, thermal expansion rates, and packaging integrity.

Environmental & Lifetime Simulation: Maintain an intrinsic understanding of electronic component and PCB manufacturing methods, failure mechanisms, and accelerated testing methodologies (such as HALT/HASS or thermal cycling) to artificially simulate decades of downhole wear-and-tear in a laboratory environment.

Obsolescence & Risk Management: Conduct critical, proactive component reviews to catch obsolescence or lead-time issues before they threaten production lines, qualifying alternative components to the exact same uncompromising standard.

Meticulous Technical Documentation: Maintain flawless, audit-ready data tracking and technical documentation regarding component testing. You must take complete ownership of communicating engineering risks clearly, backing up your conclusions with robust data that can be proudly presented to senior management and global energy clients.

Supply Chain Collaboration: Partner with internal R&D, production, and quality assurance teams, as well as external semiconductor fabs and PCB suppliers, to continually drive reliability and manufacturing yield improvements.

What is Necessary (Required Skills & Experience)

The Engineering Mindset: An analytical, systems-first mind that naturally questions how and why things fail, with a deep interest in the physical limitations of hardware and silicon electronics.

Academic OR Field-Hardened Pedigree: * A Degree in Electronic Engineering, Physics, or a closely related discipline; OR

Proven, hands-on commercial experience in electronic hardware design, validation, benchmarking, or laboratory test environments where your practical skills override a traditional certificate.

Hardware Validation Experience: Practical experience using laboratory test equipment (oscilloscopes, multimeters, environmental chambers, data loggers) to test and validate electronic sub-systems or circuitry.

Elite Documentation & Organization: Exceptional verbal and written communication skills. You must be highly structured and take pride in transforming raw test data into crystal-clear, definitive engineering reports.

Problem-Solving Autonomy: The confidence to take total accountability for an investigation, working independently to figure out testing protocols for novel hardware challenges.

Desirable Assets (The Premium Extras)

Knowledge of electronic component packaging structures, silicon wafer variations, and high-reliability screening.

Direct exposure to high-temperature or safety-critical ruggedized electronics (e.g., Downhole, Aerospace, Automotive under-the-hood, or Defense systems).

Knowledge of Accelerated Life Testing (ALT), thermal cycling models, and component wear-out mechanics.

Experience creating or optimizing internal test tracking databases to manage massive components matrices.

Ability to travel on an occasional basis to interface with external testing houses or suppliers.
