The posting

WHAT WE ARE BUILDING

Mimica https://www.mimica.ai/careers is an AI-powered process intelligence platform enabling enterprises and individuals to reclaim their most precious resource: time. We've all seen repetitive tasks and redundant processes quietly drain productivity and creativity. Not because companies don’t want to become more efficient, but because they don’t know where to start.

Mimica automatically analyzes your team’s work, then generates the AI agents to execute it. Our software turns everyday work into data-backed decisions, helping companies remove process bottlenecks, automate the right tasks, and upskill teams with precision and confidence.

We’ve raised $26 million in Series B financing and are scaling fast. Backed by investors including Khosla Ventures and Paladin Capital, our proprietary AI technology is trusted by Fortune 500 companies to accelerate transformation. Mimica is recognized as a Top 100 AI Start-up by Accel and an industry Leader by the Everest Group.

Our team

Behind our platform is a team of exceptionally talented people, remote-first and globally distributed across 16+ countries. We're looking for curious, collaborative people excited to solve complex problems. You'll join a fast-paced environment built on high ownership, bottom-up thinking, and transparent, open communication – helping some of the world's leading organizations transform the way work gets done with AI.

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 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
