Senior Product Architect – Engineering and Business Focus

Tyme

Full-time|Remote|Remote — Hong Kong

About the RoleWe are on the hunt for a talented Senior Product Architect to take charge of and refine our TymeX architecture. This role is far from a traditional design position; you will actively collaborate with product and engineering teams to make pragmatic technology choices that effectively balance speed, cost, and quality.This position requires a unique individual who can approach challenges like a business owner while executing solutions like an engineer. We seek someone who prioritizes simplicity, cost-effectiveness, and delivers substantial customer and business value. You will question costly vendor solutions, advocate for building versus buying when appropriate, and consistently inquire, "Is there a simpler, more economical solution?" Your decisions will be lived through code reviews, incident response, and operational feedback loops, ensuring your architectures are not only theoretically sound but also resilient in real-world scenarios.Note: Expat candidates will need to relocate to Ho Chi Minh City.What You'll DoDrive Product & Business ValueCollaborate with Product Owners and Engineering teams to challenge requirements and resolve genuine customer challenges.Design with empathy for the customer—slow approval processes can result in lost customers, and confusing workflows can lead to increased defaults.Prioritize based on impact; swift, uncomplicated solutions that can be deployed quickly are preferable to "perfect" architectures that take months to implement.Create lean, cost-effective systems tailored for price-sensitive markets.Lead Technical ArchitecturePromote simplicity—design systems that any engineer can quickly grasp, question assumptions, and advocate for simpler, faster, and cheaper alternatives.Architect secure, resilient, and scalable systems capable of handling peak loads and ensuring graceful failures.Bridge the gap between technology and business by translating complex technical concepts into clear business language.Enable & Grow TeamsEmpower teams to make informed decisions—guide rather than command.Engage in code reviews to validate architectural assumptions actively.Collaborate with engineers during complex implementations and production incidents.Contribute to post-mortems and operational reviews—own your designs and strive for improvements when issues arise.Mentor engineers to think architecturally and delegate decisions as teams advance.Foster a culture of psychological safety where team members feel comfortable challenging ideas and admitting mistakes.Continuously Learn & ImproveStay ahead of evolving technologies, industry best practices, and competitive landscapes.Relentlessly question assumptions—"We've always done it this way" is not a valid reason.Practice intellectual honesty: acknowledge when a design is complex due to a lack of understanding of the problem.
