Senior Reliability Engineer

We are a diverse enthusiastic and growing team of multidisciplined engineers committed to
advancing our mission of delivering mission-critical environments where it really matters through
functionality performance and reliability of HVACR products meet and exceed demanding uptime
and performance targets for applications such as data centers commercial buildings and industrial
facilities. We work across multiple development programs and often step outside our normal roles
to support a fast-paced environment.

About You and The Role
You are a hands-on engineer who partners directly with design controls testing manufacturing
service and supplier teams to deliver reliability by design for our chiller portfolio.
Youll focus on compressors (screw centrifugal scroll) heat exchangers pumps fans VFDs
(Variable Frequency Drives) power electronics sensors/actuators and control systemsand the
interactions among themto ensure products meet stringent reliability availability and
maintainability goals over the entire lifecycle.
You will apply DFMEA (Design Failure Modes & Effects Analysis) Accelerated testing RCA (Root
Cause Analysis)/8D (Problem solving) and statistical life data analysis to drive decisions.
We are the knowledge holders for how to validate field driven use cases define critical parameters
and guide Cross functional execution so proper scope and timely outcomes are achieved.
What Youll Do
Own and drive the reliability strategy across air-cooled and water-cooled chiller
programs with clear goals for failure-rate reduction B10 life and warranty cost.
Translate design intent into reliability plans (Design-for-Reliability DVP&R - Design
Verification Plan and Results) ensuring coverage of likely failure modes under realistic
environmental and load profiles (thermal cycling vibration electrical stress fouling).
Manage and report reliability status for all programsdashboards risk registers and
readiness for phase gatesleading data-driven decisions.
Connect field failure modes with validation standards and plans; update strategies as
new field learnings emerge.
Review
Requirements and validation methods to ensure whats written matches how its
verified and validated.
Program test strategies to maximize coverage and reduce redundant testing.
Program readiness at key milestones (concept design freeze design validation
product validation launch).
Conduct Root Cause Analysis (RCA/8D) on chronic issues across disciplines (e.g. bearing
wear VFD trips refrigerant leaks corrosion) and implement systemic corrective actions.
Standardize reliability practices (DFMEA Accelerated testing) with principal engineers
and align supplier qualifications to reliability needs
Must have Requirements
Bachelors degree in electrical Mechatronics Mechanical or related engineering discipline.
7-10 years of experience in product development test or field reliability;
Understanding of FMEA RCA recreating failure modes and statistical analysis (e.g. Weibull)
Experience in designing and executing accelerated testing Reliability testing.
Failure analysis experience.
Demonstrated aptitude for debugging and troubleshooting in lab and field environments;
strong curiosity and systematic problem solving
Preferred qualifications
Certified Reliability Engineer (ASQ-CRE) or equivalent and understands distributions Life
Stress models Reliability allocations Design of Experiments (DoE)
Ability to analyze test/field data generate reliability reports and communicate findings to
drive design and process improvements.
Familiarity with electronics & controls (sensors HMIs drives) electro-mechanical interactions
and manufacturing processes affecting reliability.
PART 2
Day to Day (what a typical day or week looks like in this role)
Review DFMEA DVP&R field data and customer duty cycles for a new chiller platforms;
identify knowledge gaps and key risk areas; propose targeted reliability tests.
Create reliability test requests with clear purpose hypotheses/predictions and acceptance
criteria; align labs on configurations fixtures and schedules.
Lead cross-functional discussions (design controls manufacturing supply chain service) to
confirm deliverables test readiness and maturity; align on phase-gate expectations.
Coordinate with lab personnel to ensure samples instrumentation and test stands (water
loops ambient chambers power cycling rigs vibration tables) meet the plan; manage
execution across multiple labs.
Review lab reports for completeness and traceability to requirements; ensure failure
evidence stress profiles and data quality are adequate for decisions.
Facilitate RCA/8D on failures (e.g. compressor internals electronics thermal stress
refrigerant circuit leaks) and define effective short- and long-term corrective actions.
Summarize test conclusions; document risks and defects; drive systemic learning. Use DoE
where needed to confirm causeeffect and optimize design margins.
Assess platform cross-impactidentify other models/options sharing similar riskand
communicate proactively to stakeholders.
Lead process improvements in verification & validation and reliability standard work (gate
criteria stress profiles acceptance tests).
Engage with quality and service teams to capture field use cases (BMS logs alarms
ambient/wet-bulb trends) perform site investigations when needed and translate learnings
into tests.
Maintain reliability dashboards (program status risks actions) and trackers; keep Test-to
Fail / Test-to-Learn (TTF/TTL) metrics current and visible.
