Staff/Senior Backend Engineer (Node.js)

What we are building

Mimica's mission is to empower enterprises, teams, and individuals to reclaim their most precious resource — time and work more efficiently, with greater purpose and impact.

Our AI-powered task mining observes employee actions across the desktop and categorizes them into detailed process maps. Mimica’s process intelligence highlights inefficiencies, prioritizes improvements based on ROI, recommends the optimal technology for automation (RPA, intelligent document processing, GenAI), and provides a blueprint for building new automations and transforming work.

Our approach to engineering

• We prioritize customer needs first
• We work in small, project-based teams
• We have flexibility in terms of the problems we work on
• We own the full lifecycle of our projects
• We avoid silos and encourage taking up tasks in new areas
• We balance quality and velocity
• We have a shared responsibility for our production code
• We each set our own routine to maximize our productivity

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.
• 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.
