Staff/Lead Fullstack Engineer (Data Structures Expert)

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.

Where we are in our scale-up journey

We’ve achieved strong product-market fit and are now scaling with intention. You’ll join a 45-person team of Senior+ engineers and Product leaders who prioritise product impact over mere headcount. We have 8 cross-functional teams, including a dedicated Platform team focused on infra & developer experience. We started building proprietary ML before the LLM boom, so we don't just consume models - we train them from the ground up.

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 improve and expand the capabilities of the Mimica Webapp (MERN stack). This means designing a robust architecture, developing new features, releasing improvements to existing components and taking operational responsibility for what you build. You will seek to understand user needs and pain points, experiment and iterate on your solutions, leveraging tight feedback loops.

You‘ll have the opportunity to shape our technical direction, processes and culture.

Part of your day-to-day

• Developing a visualisation tool and a data-rich dashboard that display process flows and metrics in novel ways, with scalability in mind.

• Building interfaces and real-time frontend services that enable multiple users to edit graph data and re-train AI models through their input.

• Owning projects end-to-end as part of small teams, collaborating with our TLs and Product Managers.

• Participating in architectural decisions, collaborating across teams to identify and implement product improvements and producing documentation for your implementations.

• Providing feedback to peers through RFCs, 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.

Who you are

• You have at least 8+ years of experience as a Software Engineer and high engineering standards.

• Proven experience in architecting scalable and reusable UI components and algorithms that efficiently handle large datasets.

• Experienced and comfortable with Redux and Node.js

• Knowledge of advanced system design principles, data structures, algorithms, and the core concepts underlying scalable and reliable architectures.

• Deep understanding of advanced performance optimisation techniques across front-end and backend.

• Committed to upholding high engineering standards, delivering clean, testable, reusable, modular, and well-documented code.

• Experience owning projects from start to finish, including speccing, design, development, testing, deployment, release and observ.

• Drive to 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

• Background working in fast-paced, successful scale-up environments or as a founding engineer, with a track record of delivering value quickly and iteratively.

• Experience with Graph or Canvas-based Rendering, or graph/geometry editing.
