What you'll do

As written by Mimica · Read the original

Your mission

In this role, your mission will be to enhance and scale the backend systems powering the Mimica platform (MERN stack). This means designing and implementing a scalable architecture, developing and optimizing backend services and APIs, improving the performance and reliability of existing components, and taking operational responsibility for what you build.  As a member of our early engineering team, you‘ll have the opportunity to shape our technical direction, processes and culture.

Part of your day-to-day

  • Contributing to architectural decisions and collaborating across teams to identify and implement product improvements.

  • Developing and optimizing a real-time backend service that enables multiple users to edit graph data and re-train AI models through their input.

  • Creating libraries and building APIs in our Node.js backend to interact with the various ML components of the system.

  • Diagnozing fault-tolerance and availability issues, as well as performance bottlenecks, and resolving them.

  • Refactoring our components and services and producing documentation for your implementations.

  • Providing feedback to peers through pair programming and code reviews and helping those around you to level up.

  • Participating in hiring and onboarding new team members; taking on end-to-end project management responsibilities as we grow.


What you will bring

  • Background in backend engineering, focusing on developing high-performance production software and scalable architectures.

Requirements

Minimum 8 years of experience as a Software Engineer.

  • Proficiency in TypeScript, and experience using modern frameworks and technologies (e.g., Docker, K8s) to build high-throughput, low-latency systems.

  • Practical experience in designing APIs and managing databases (e.g., PostgreSQL, MongoDB), with a keen eye for query optimization and efficient data storage & handling.

  • Firm grasp of distributed systems concepts and techniques – microservices, load balancing, caching, horizontal/vertical scaling and stateless architectures.

  • Commitment to upholding high engineering standards, prioritizing code quality, maintainability, reliability, and security.

  • Strong analytical and troubleshooting skills – methodically decomposing systems to identify bottlenecks, determine root causes, and implement effective solutions.

  • Drive to continually develop your skills, improve team processes and reduce debt.

  • Fluency in English, with effective communication skills – articulating complex ideas, concepts, and trade-offs clearly.

    • Bonus

    • Experience and fluency with Python.

    • Experience working within an international high-impact Startup/Scale-up environment – delivering value quickly and iteratively.

    • Active interest in AI, automation, or related fields.

    We’d love to hear from you, even if you feel you don’t quite have all of the above.
