Our client is hiring a Senior Product Engineer to help build a category-defining SaaS platform from the ground up. This is a high-impact role for a full-stack engineer with strong product instincts who thrives in early-stage, high-autonomy environments.
The role
Lead full-stack development of core product features from concept to launch.
Translate raw business objectives into simple, intuitive customer experiences.
Drive product discovery through user interviews, workflow mapping and rapid iteration.
Apply AI/LLMs pragmatically — accelerating development, powering features and automating complex workflows.
Own technical architecture, infrastructure decisions and quality standards.
Collaborate closely with domain experts to deeply understand real user problems.
What we/re looking for
- 5+ years as a full-stack or product-focused engineer in startup environments.
- Strong skills across modern frontend frameworks (e.g. React/TypeScript) and backend development (Go, Node, Python or similar).
- Proven experience taking products from 0→1 and shipping polished customer-facing features.
- Comfortable leading product discovery — not just execution.
- Deep interest in AI/LLMs and their application in real products.
Why this role
You’ll work at the intersection of engineering, product, AI and design, turning ambiguous business problems into elegant, customer-facing features. You’ll own features end-to-end — from user discovery and solution design through to production delivery — often building solo and close to the founders.
