Job Description

IT Jobs. Sun King (Formerly Greenlight Planet) Jobs

The role holder be in charge of working with cross-functional teams to design and enhance user-cantered cooking products and services. The designer will be identifying customer pain points, developing and testing hardware and digital solutions, and refining designs based on field insights to ensure safety, efficiency, and user satisfaction across diverse markets.

Discovery & Problem Framing

  • Partner with product managers, engineers, and researchers to identify key cooking-related pain points through field visits, customer interviews, and data insights.
  • Master the entire customer journey—from fuel refills to payment top-ups, stove usage to safety checks—in both urban and rural last-mile environments.
  • Define opportunities where thoughtful product and service design can improve access, safety, efficiency, and user satisfaction.

Ideation & Solution Design and Hardware & UX Integration

  • Design user experiences that seamlessly intergrate hardware (LPG stoves, cylinders, valves, induction devices) with embedded and digital interfaces (e.g. displays, mobile apps, SMS prompts).
  • Develop app and service model prototypes, wireframes, and trials to trial new concepts and validate production-ready improvements.
  • Shape the physical product form—including ergonomics, CMF (Color, Material, Finish), heat safety, and component placement in contexts where our customers live.

Service Design & Customer Journey Mapping

  • Map the full customer journey from product purchase and installation to usage, refuelling, servicing, and end-of-life.
  • Design service blueprints that optimize delivery, maintenance, customer assistance, and agent interactions.
  • Identify moments of friction (e.g. gas refill logistics, digital payments) and co-create practical, user-friendly solutions.

Prototyping & Concept Development

  • Create and iterate through physical mock ups with the assistance of the hardware development team, (3D prints, CAD models) and digital prototypes (Figma, wireframes, storyboards).
  • Use scenario-based storytelling to show how customers interact with products in their daily lives—considering household roles, fuel cost dynamics, and mobile literacy.

User Testing & Validation

  • Steer field usability tests for both product hardware and service flows (e.g. how users top up gas, interpret safety signals, or operate an induction panel).
  • Conduct ergonomic evaluations for real-world cooking settings—considering counter space, pot size, heating time, and safety.
  • Iterate designs based on insights from live pilots and agent/customer feedback loops.
  • Care deeply about real-world impact and designing for underserved communities.
  • Thrive in cross-functional teams solving complex system-level problems across hardware, software, and service.
  • Comprehend how to prototype fast, test in the field, and learn from real users—across languages, geographies, and infrastructure constraints.
  • Want to help shape the future of clean cooking, while contributing to climate, gender, and health outcomes.
