Staff/Lead Python Engineer (FastAPI, Orchestration)

About this role

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.

At the click of a button, Mimica identifies every process improvement and agentic AI opportunity across an enterprise. 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.

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.

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 prioritise 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 maximise our productivity

WHAT WILL YOU OWN

In this role, you will own and support the development of backend systems that interface with ML models. You will build apps and core components of our ML systems, deliver new AI features and drive improvements to our infrastructure and services.

We are currently looking for Engineers to join one of our teams:

- Data Intelligence Team, whose goal is to provide ML-enriched data for downstream tasks and ensure user data privacy. You will support our data orchestration and processing pipeline, as we build with scalability in mind.

- Miner Team, whose goal is to enable rapid and accurate labelling and segmentation of data in the Miner product through automation and ML methods. You will support the automation and scalability of the existing ML systems that back up our Miner product.

- Maker Team, a team responsible for building out the automation engine, as one of its founding members. We're building a new product from scratch, and that means being a part of the design of its architecture, experimentation and development.

In all cases, we're looking for a Lead/Staff-level engineer to join the Python Chapter, who will have the opportunity to shape our technical direction, architecture, processes, and culture, and to level up the team and Chapter in development practices.

- Developing observability for new and existing ML applications and GenAI/LLM integrations, making use of the Grafana Stack (Prometheus, Loki, Tempo)

- Develop integrations and services that communicate with Google Services.

- Working closely with Data Scientists and ML Engineers throughout the lifecycle of productionising their models

- Being responsive to incidents regarding ML applications - including an understanding of how to triage and resolve issues relating to CPU, memory, and GPU utilisation

- Documenting procedures and guides to facilitate knowledge sharing and help other engineers level up through pairing and mentoring

- Participating in hiring and onboarding new team members; taking on end-to-end project management responsibilities as we grow.

WHO ARE WE'RE LOOKING FOR:

- At least 8 years of experience and above as a Software Engineer, and previous Lead/Staff/Principal level of responsibilities.
