We are a global technology group built for what's next, offering high calibre professionals the platform for high stakes work, the kind of work that defines an entire career. When you join us, you're not just taking on projects, you're solving problems that don't even have answers yet.
You will join the exclusive roster of talent that global leaders, including Google, Snap, Diageo, PayPal, and Jaguar Land Rover call when deadlines seem impossible, when others have already tried and failed, and when the solution absolutely has to work.
Forget routine consultancy. You will operate where technology, design, and human behaviour meet to deliver tangible outcomes, fast. This is work that leaves a mark, work you’ll be proud to tell your friends about.
Qodea is built for what’s next. An environment where your skills will evolve at the frontier of innovation and AI, ensuring continuous growth and development.
Due to several significant client wins, we are looking to connect with Senior AI Engineers to design, build, and productionise autonomous, agentic AI systems that deliver measurable product and business outcomes. You will translate high-level objecives into reliable, safe, and efficient agent architectures using LLMs, retrieval, and orchestration layers.
We look for people who embody:
Innovation to solve the hardest problems.
Accountability for every result.
Integrity always.
We believe our best work happens when we connect. While we operate a flexible model, we expect you to spend 60% of your time on-site at our London office or a client location for collaboration sessions and workshops.
About the role.
We are looking for a backend engineer to take ownership of core backend services powering Google Beacon. The role involves designing and maintaining distributed systems on Google Cloud, with a strong focus on scalability, performance, and reliability across large-scale audit workloads.
Backend Development (Python / FastAPI)
Design and maintain RESTful APIs using Python 3.12 and FastAPI. Implement robust data modeling using Pydantic and manage persistence layers with Google Cloud Datastore (NoSQL).
Distributed Architecture on GCP
Build and maintain asynchronous, event-driven systems using Cloud Run, Cloud Tasks, and Pub/Sub to orchestrate workers processing high volumes of concurrent tasks.
Scalable Data Processing
Develop and optimize batch processing and aggregation pipelines. Improve query performance and system scalability to support large audit datasets.
CI/CD & Infrastructure
Maintain and improve GCP Cloud Build pipelines. Manage Docker-based containerization and deployment workflows across development, QA, UAT, and production environments.
AI Integration
Integrate and maintain AI-powered components using Gemini via Vertex AI within backend worker services.
Release & Environment Management
Coordinate deployments and release cycles across multiple environments, ensuring stability and operational readiness.
Test-Driven Development & Quality Discipline — Maintain and extend a mature TDD workflow backed by 2,000+ unit tests, ensuring regression safety, deterministic behavior, and confidence in large-scale refactors. Enforce testing standards and code coverage practices to prevent unintended changes across distributed systems.
Requirements
- Strong experience with Python (asyncio preferred)
- Production experience with FastAPI or similar frameworks
- Hands-on experience with Google Cloud Platform
- Experience designing distributed or event-driven systems
- Comfortable owning features end-to-end, from design to deployment
