Key responsibilities include:

• Developing and implementing reliability test strategies for new products to maximize field life and minimize early life failures
• Working closely with hardware and software engineering teams to maximize reliability across all disciplines
• Designing and executing novel environmental, RF, mechanical, and electrical testing techniques tailored to the product and its functions
• Writing test programs to exercise the functionality of the product over various conditions and environments
• Automating reliability test initiatives and reporting using proper data visualization techniques and thorough knowledge of the product and its functions
• Defining the ongoing reliability testing strategy to monitor the manufacturing process health and screen for long-term reliability defects caused by process and component variability
• Root cause systemic production issues or failures found in test and drive design or process changes to meet long-term reliability goals

Requirements include:

• Bachelor's degree in an engineering discipline
• 5+ years of experience in test, analysis, manufacturing, or hardware development
• Thorough understanding and experience in environmental testing such as HALT/HASS, thermal, vibration, and TVAC
• Programming experience in Python, C, and SQL with an emphasis on data analysis and automation
• Demonstrated capability to think creatively and solve complex problems with little to no supervision on schedule
• Thorough understanding of electronics reliability and failure mechanisms
• Demonstrated ability to work in a highly cross-functional role

Bonus requirements include:

• Experience with both electronics and mechanical design and analysis, including knowledge of RF principles
• Experience in a fast-paced, iterative design environment within the consumer electronics, medical devices, aerospace, marine, or automotive industries
• Demonstrated application of design or process validation and control methods such as DFMEA, PFMEA, design of experiments (DOE), and statistical process control (SPC)
• Thorough understanding of electrical schematics and electronics manufacturing to analyze and improve test coverage
• Hands-on experience qualifying and maintaining manufacturing processes for electronics and/or mechanical assemblies
• Excellent communication skills, written and verbal. Ability to produce executive-level reports and presentations to efficiently convey information about large data sets

We have recently expanded our capabilities in mechanical and thermal simulations, and in this role, you will have a direct impact on the design and quality of future Varjo products. This is your chance to shape the next generation of high-end VR/XR hardware.

Responsibilities

• Define, develop and execute system- and component-level hardware reliability and environmental test strategies for Varjo products.
• Plan and execute comprehensive verification and validation activities from the early R&D phase through the entire product lifecycle.
• Lead, coordinate and execute reliability and environmental testing using both in-house laboratory and external test partners.
• Create and manage test plans, detailed reports, and executive summaries to drive data-driven decision-making.
• Proactively support HW design team by providing Design for Reliability guidance during design reviews and support component qualification activities.
• Lead failure investigations and root cause analysis to identify potential design or manufacturing issues.
• Develop, implement, and improve Varjo internal reliability testing standards and processes.

Our Expectations

• B.Sc. or M.Sc. on a related technical field.
• Proven track record of 7+ years in complex electro-mechanical product reliability testing, preferably within consumer electronics, optoelectronics, wearable products...
• Hands-on experience with reliability test and laboratory equipment, including environmental chambers (thermal cycling, humidity, combined), vibration and shock test systems, ingress protection test setups (IP rating).
• Willingness and ability to specify, build, and qualify new test equipment and develop of in-house laboratory capabilities.
• Deep understanding of environmental testing (e.g., thermal, humidity, vibration, drop, and ingress protection) and relevant standards (IEC, MIL-STD).
• Proficiency in reliability methodologies such as FMEA (Failure Mode and Effects Analysis), HALT/HASS, and statistical analysis (e.g., Weibull, MTBF).
• Excellent collaboration skills and the ability to support cross-functional stakeholders (Design, Project management, Sourcing, Manufacturing).
• A strong network of external testing and validation partners
• Fluency in English

This is a hands-on role in our Helsinki-based team. Because you'll be working with physical devices and prototypes, the work will be performed mostly on site at our headquarters in Kaisaniemi. Full remote work is not possible in this role.

Benefits

• Opportunity to take part in creating the new state-of-the-art in virtual and mixed reality experiences.
• A low-hierarchy culture with minimal bureaucracy and maximum opportunity for you to take charge of your work.
• An international working environment with tons of opportunities to learn and grow with the company.
