Backend Engineer (MERN Stack)

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.
• Diagnosing 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.
• Minimum 8 years of experience as a Software Engineer.
• Proficiency in JavaScript/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 owning projects from start to finish, including speccing, architecture, development, testing, deployment, release and monitoring.
• 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.
