Job location: Hyderabad
About the role:
Sun King’s Clean Cooking unit provides pay‑as‑you‑go access to LPG via domestic cylinders, enabled by the proprietary Flow Monitoring and Control Device (FMCD). The FMCD — and the broader family of sensing‑based products — is central to delivering reliable service. The Hardware Validation Engineer ensures product and equipment designs meet defined requirements through rigorous validation testing, clear documentation, and actionable insights for design and manufacturing teams.
1. Design Validation Test Planning & Execution
- Test Plan Development: Create detailed test plans linking requirements to performance targets, covering reliability, safety, and environmental needs.
- Test Procedures: Write clear, repeatable, version‑controlled procedures aligned with current design specs.
- Laboratory Testing: Execute tests, operate equipment, record results, and flag anomalies promptly.
- Fixture Support: Collaborate with engineering teams to design and validate test fixtures for accuracy and repeatability.
- Results Analysis: Analyze outcomes, identify failure modes, and report findings with clear pass/fail decisions and recommendations.
2. Documentation, Traceability & Version Control
- Requirements Traceability: Maintain strong linkage between requirements, test methods, results, and design revisions.
- Document Control: Own version control for test plans, procedures, and reports, ensuring compliance with configuration standards.
- Design Change Validation: Assess the impact of revisions and run targeted validation to confirm compliance.
- Record Management: Keep complete, auditable validation records to support reviews, compliance, and knowledge transfer.
3. Cross‑Functional Collaboration & Partner Oversight
- Team Collaboration: Work with design, manufacturing, and quality teams to align validation with development milestones and production readiness.
- Partner Oversight (Satruc): Review and monitor Satruc’s Design Validation Testing programs, ensuring compliance with Sun King standards.
- Test Readiness Reviews: Confirm fixtures, procedures, calibration, and test articles are in order before campaigns.
- Failure Investigation: Lead structured root‑cause analysis, document findings, and verify corrective actions.
- Production Readiness: Provide validation data and sign‑off support for readiness gates, ensuring requirements are met and open items tracked.
-
Bachelor’s degree in Mechanical, Electrical, Mechatronics, or related engineering discipline, or equivalent experience.
- 3–5+ years in hardware validation, test engineering, or product verification for products combining mechanical, electronic, and electromechanical components.
- Familiarity with both functional and environmental testing.
- Proven ability to write test plans and procedures directly from requirements.
- Experience designing or supporting test fixtures, jigs, or automated test equipment.
- Track record of working cross‑functionally with design and manufacturing teams to communicate validation findings.
- Exposure to partner or supplier oversight in a technical context (reviewing test execution, accepting results, or managing test partners) is a plus.
Technical Skills
- Strong documentation skills: structured, version‑controlled, and traceable to requirements.
- Working knowledge of requirements traceability and configuration management.
- Ability to interpret mechanical drawings, BOMs, assembly schematics, and basic PCB schematics.
- Experience with validation methods: performance, environmental stress (temperature, humidity, vibration), and reliability/life testing.
- Familiarity with failure evaluation tools such as 5‑Why, Fishbone, or FMEA.
- Competence in data analysis using Excel or equivalent; CAD tools, data acquisition systems, or Python/SQL are a plus.
- Familiarity with AI‑supported tools for documentation, test data evaluation, or test script development is a plus.
Attributes
- Rigorous approach to documentation; produces test plans and records to a high standard with minimal review.
- Detail‑oriented and disciplined in test execution, with sound judgment on when to escalate deviations.
- Skilled at translating technical findings into clear insights for non‑specialist audiences.
- Self‑directed and organized, able to manage multiple test programs and set priorities independently.
- Strong cross‑functional communication skills, effective at the intersection of design, manufacturing, and quality.
-
Professional growth in a dynamic, rapidly expanding, high-social-impact industry
- An open-minded, collaborative culture made up of enthusiastic colleagues who are driven by the challenge of innovation towards profound impact on people and the planet.
- A truly multicultural experience: you will have the chance to work with and learn from people from different geographies, nationalities, and backgrounds.
- Structured, tailored learning and development programs that help you become a better leader, manager, and professional through the Sun King Center for Leadership.
Sun King is the world’s leading off-grid solar energy company, combining cutting-edge product design, fintech, and field operations to deliver energy access for the 1.8 billion people who live without an affordable and reliable electric-grid connection.
Sun King has built a new kind of energy utility: distributed, green, customer-centric, and affordable. We bring clean, reliable, decentralized energy directly into people’s lives — from solar kits that provide first-time energy access to multi-kilowatt systems that serve both off-grid users and grid-connected customers powering larger homes, schools, hospitals, farms, offices, and light manufacturing.
Already, 25 million homes and businesses rely on Sun King for electricity supply and the appliances and services it enables: lighting, televisions, fans, refrigeration, and smartphones.
Sun King combines energy generation, energy-efficient appliances, installation, and financing into one seamless offering. Think of it as a distributed utility, designed for wherever energy is needed and designed to scale with its users as incomes and energy needs grow.
Sun King makes solar products affordable to low-income households and businesses via ‘pay-as-you-go’ (PAYG) purchase financing. Sun King installs solar after customers pay a small deposit. Customers then make small, manageable payments of as little as US $0.14 a day via mobile money or cash.
Instead of paying for expensive, polluting, and health-damaging kerosene for lighting or diesel for power, customers unlock savings through accessing solar power and after one to two years of payments, customers own their solar equipment outright.
Sun King collects payments digitally through mobile money systems and its 35,000 field agents — over 1 million payments each day. To date, Sun King has extended more than $1.4 billion in PAYG loans to customers.
Sun King began by powering homes and businesses with solar systems delivered through PAYG financing. Now, we’re using the same model to make smartphones and clean cooking equipment affordable: helping households connect to the digital economy and transition from wood-based fuels to modern, sustainable alternatives.
Sun King employs 3,500 full-time staff in 14 countries, with specialties spanning product design, data science, logistics, customer service, sales, software, operations, and more — all with a passion to serve off-grid families. Sun King is committed to gender diversity in the workplace. Women represent 42% of Sun King’s workforce.
