• We’re looking for a Product Engineer with a strong frontend specialization, a solid technical foundation, and experience working on SaaS products in Agile environments. • You’ll help us build high-quality user experiences, with deep ownership of the user interface, interaction patterns, performance, accessibility, and the overall quality of our apps. • While your core focus will be frontend, we value an end-to-end product mindset and openness to extending your impact into backend or mobile systems where needed, bridging the gap with the support of AI. • You will join a product squad and work closely with designers, product managers, and experienced engineers across backend, frontend, mobile, and AI. • The role is moving toward end-to-end ownership—focusing on understanding user problems, shaping product decisions, rapid prototyping, and validating ideas, rather than just coding from strict specs. • The company is undergoing this transformation itself; you aren't expected to have everything figured out from day one. • What matters most is your curiosity, adaptability, strong engineering judgment, and a genuine willingness to learn new ways of working. • You will receive the tools, practices, and team environment needed to evolve into a product-minded, AI-enabled engineer while continuing to deepen your technical expertise.
