Senior Software Engineer (Full-Stack)
About the role
Hiring a senior full-stack engineer to join our team and focused on product engineering. As a senior engineer at Replo, you will play a pivotal role in both shaping core product architecture and driving end-to-end feature development that directly impacts hundreds of thousands of users.
You’ll start as a senior contributor working on core products including our AI platform, inventory, checkout, analytics, and integration with 3rd-party providers. You’ll own these critical product surfaces end-to-end, from architecture to deployment, with no layers of management in between.
As Replo grows, so will your scope. You’ll set technical direction, mentor engineers, and define best practices across the team. If you’re interested, this can evolve into managing projects and eventually teams, while shipping great products and staying close to the code.
Responsibilities
Lead and grow a team of exceptional engineers, providing mentorship and guidance to help them succeed and thrive.
Deeply understand customer needs and pain points to prioritize work and deliver solutions that drive real impact.
Own project execution end-to-end — planning, architecture, and delivery — while maintaining high quality and predictable timelines.
Collaborate with high-visibility teams and stakeholders to drive critical product and platform initiatives forward.
Provide hands-on technical leadership, from system architecture and design to incident response and roadmap definition.
Work every day with founders to shape and execute on the long-term vision for Replo's AI platform.
Partner with our Chief of Staff to attract top-tier engineering talent and define hiring strategies as the team scales.

Architecting and implementing full-stack product features. Real examples include —
Enable merchants to sell anything, anywhere, including subscriptions, dropshipping, and digital products in one platform
Build agentic workflows that design and build online shops for anyone, from SaaS startups to M&Ms
