Rust Jobs for Rustaceans

About the Role
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.

Key Responsibilities:
In your first months, you’ll explore...

• Learn about how we deliver world-class biometric technologies to millions of users, from the initial research and development phases through to deployment and ongoing support, ensuring scalability and reliability.
• Learn about the fundamental principles of biometric recognition, including various modalities (e.g., face, fingerprint, iris), their underlying algorithms, and the ethical considerations involved in their application.
• Learn about how we efficiently execute AI models on a wide range of target devices and platforms, from resource-constrained embedded systems and mobile devices to high-throughput cloud infrastructure, optimizing for performance, accuracy, and power consumption.
  As you settle into the role, you’ll start contributing by...
• Contribute to the design and architecture of the next generation of biometric SDKs, focusing on performance, scalability, and maintainability.
• Develop robust and efficient software solutions following best practices in software engineering, including code reviews, testing, and documentation.
• Actively contribute to the evolution of internal engineering standards, tools, and processes to enhance team productivity and code quality.
  Within your first year, you’ll have the opportunity to...
• Identify and implement optimizations in the model delivery pipeline, from training artifact management to deployment mechanisms, to ensure seamless integration and usage across different teams.
• Collaborate closely with the AI teams to understand their model outputs and consumption requirements, developing robust and scalable solutions that bridge the gap between AI research and practical application.
• Provide expert guidance and technical leadership within the SDK team, influencing architectural decisions and fostering best practices for the design and implementation of new features that enhance model delivery and consumption.

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.
