Help us redefine digital payments, and grow the people building them.

You take ownership. Not just over your code, but over architectural decisions, system health, and how a team develops. You like working in environments where things are growing, evolving, and not everything is fully defined yet. Where your experience actually matters.

You care about building things the right way, but also about how people work together. Coaching others, challenging ideas, and having meaningful technical discussions gives you energy. You're looking for a role where you can combine technical depth with real influence.

This role gives you exactly that.

Why this role exists

As Mechhive continues to grow, our platforms handle increasing volumes, more integrations, and higher expectations around reliability and performance. Our systems process thousands of transactions daily across three platforms, working with dozens of external partners and payment providers. To support this growth, our engineering team has expanded rapidly.

That combination requires senior engineers who:

• Take ownership of technical direction
• Act as sparring partners for both the team and management
• Help keep systems scalable and teams effective

Our mission is to redefine payment experiences through simple, intuitive, and innovative solutions that empower people to transact on their own terms. Our vision is to lead digital payments innovation globally and give everyone the freedom to transact effortlessly. Achieving that starts with how we build, and with the people who build it.
