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.\nMimica 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.\nWe’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.\nOur team\nBehind 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.\nOur approach to engineering\nWe prioritize customer needs first\n\nWe work in small, project-based teams\n\nWe have flexibility in terms of the problems we work on\n\nWe own the full lifecycle of our projects\n\nWe avoid silos and encourage taking up tasks in new areas\n\nWe balance quality and velocity\n\nWe have a shared responsibility for our production code\n\nWe each set our own routine to maximize our productivity\n\nYour mission\nIn 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.\nPart of your day-to-day\nContributing to architectural decisions and collaborating across teams to identify and implement product improvements.\n\nDeveloping and optimizing a real-time backend service that enables multiple users to edit graph data and re-train AI models through their input.\n\nCreating libraries and building APIs in our Node.js backend to interact with the various ML components of the system.\n\nDiagnozing fault-tolerance and availability issues, as well as performance bottlenecks, and resolving them.\n\nRefactoring our components and services and producing documentation for your implementations.\n\nProviding feedback to peers through pair programming and code reviews and helping those around you to level up.\n\nParticipating in hiring and onboarding new team members; taking on end-to-end project management responsibilities as we grow.\n\nWhat you will bring\nBackground in backend engineering, focusing ondeveloping high-performance production software and scalable architectures.\n\nMinimum 8 years of experience as a Software Engineer.\n\nProficiency in TypeScript, and experience using modern frameworks and technologies (e.g., Docker, K8s) to build high-throughput, low-latency systems.\n\nPractical experience in designing APIs and managing databases (e.g., PostgreSQL, MongoDB), with a keen eye for query optimization and efficient data storage & handling.\n\nFirm grasp of distributed systems concepts and techniques - microservices, load balancing, caching, horizontal/vertical scaling and stateless architectures.\n\nCommitment to upholding high engineering standards, prioritizing code quality, maintainability, reliability, and security.\n\nStrong analytical and troubleshooting skills - methodically decomposing systems to identify bottlenecks, determine root causes, and implement effective solutions.\n\nDrive to continually develop your skills, improve team processes and reduce debt.\n\nFluency in English, with effective communication skills - articulating complex ideas, concepts, and trade-offs clearly.\n\nBonus\nExperience and fluency with Python.\n\nExperience working within an international high-impact Startup/Scale-up environment - delivering value quickly and iteratively.\n\nActive interest in AI, automation, or related fields.\n\nWe’d love to hear from you, even if you feel you don’t quite have all of the above.\nLocation\nThis is a fully remote position.
