Java/Kotlin Experienced Software Engineer

Job Description

What You’ll Help Build:

At Innovatrics, we build biometric technologies for elections, border control, digital ID, and secure onboarding in 80+ countries. Our algorithms have reached over a billion people. 

Your work here won’t get lost in a backlog; it’ll shape real-world systems that matter. 

We’re a small team, so your ideas ship fast. From day one, you’ll build production features and shape global-scale projects within weeks.

Responsibilities

Why This Job Is Exciting:

At Innovatrics, we equip you with the tools, context, and trust to thrive. Our opportunity-driven roadmap highlights how you can grow, contribute, and make a meaningful impact throughout your journey with us.

In your first months, you’ll...

• Get hands-on with our services, most of which are written in Kotlin and use the gRPC framework with Protocol Buffers (Protobuf) for data serialization.
• Learn the ins and outs of our architecture and development workflows.
• Deliver small bug fixes and enhancements to help you become familiar with the system.

As you settle into the role, you’ll...

• Contribute actively to the development and optimization of our Biometric Services team’s components.
• Participate in the design of new features and API improvements.
• Collaborate with engineers across teams to ensure high performance, scalability, and clean architecture.

Within your first year, you’ll...

• Influence architecture and technical strategy across services.
• Provide expert input on Java/Kotlin development and API design.
• Mentor junior engineers and help shape coding standards and best practices.
