Senior Software Engineer

Company: KeyPleaz

Location: Remote (U.S. preferred)

Reports to: CTO

KeyPleaz is a property access and coordination platform that helps manage entry, scheduling, and logistics across real-world locations. We work with property managers, service providers, and partners to replace manual, fragmented processes with secure, reliable software. Think about it as Uber for Real Estate Agents.

Our platform operates where digital systems meet physical access, which means quality, reliability, and thoughtful engineering matter.

We are seeking a Senior Software Engineer to help build, scale, and maintain the KeyPleaz platform. KeyPleaz began in 2019 and is in production today. This is a hands-on role for an experienced engineer who can own features end-to-end, contribute across the stack, and help guide technical decisions as the platform grows.

We hire for ownership and execution. Technical competence is table stakes. What differentiates top performers on our team is personal ownership, disciplined execution, and proactive problem solving. We look for engineers who treat the product like their own business—who communicate clearly, move fast with accountability, and finish what they start.

You will work closely with product, operations, and leadership to deliver stable, scalable solutions used daily by customers and partners.
