Backend Software Engineer Python

Backend Software Engineer Python Overview

An experienced backend engineer is sought for a London-based role focused on Python development within an innovative technology business building the next generation of intelligent software platforms. The position centers on complex, large-scale backend systems that connect real-world devices with modern cloud and data infrastructure, with a strong emphasis on handling high volumes of real-time data reliably and efficiently.

The work is highly technical and hands-on, involving the design and scaling of backend architecture for mission-critical operations. You would be contributing to systems that need to perform well across diverse environments, with responsibilities spanning API development, database optimisation, performance tuning, and the delivery of production-ready software.

What you would be doing

• Designing and extending backend services that support a platform connecting physical devices with cloud-based and data-driven systems.
• Creating backend architecture that can cope with very large streams of real-time information and remain stable at scale.
• Building dependable APIs that underpin important operational workflows.
• Writing high-quality Python code with an emphasis on clarity, speed, and maintainability.
• Improving database efficiency by refining queries and working with PostgreSQL and SQLAlchemy.
• Supporting the performance, reliability, and scalability of distributed backend components.
• Contributing to platform capabilities that may involve streaming data, IoT or edge environments, and machine learning inference.
• Working closely with colleagues from other disciplines to deliver software in a fast-paced environment.
• Taking part in testing, deployment, and CI/CD practices for production systems.
• Helping to optimise systems where scale, responsiveness, and throughput are critical.

What the employer is looking for

• Substantial backend engineering experience, with a track record of producing clean and efficient code.
• Strong Python expertise, particularly with FastAPI and Pydantic.
• Experience using PostgreSQL and SQLAlchemy in real projects.
• Hands-on knowledge of AWS.
• Exposure to distributed systems technologies such as Redis and Celery.
• Additional experience with machine learning inference tooling or platforms, including GCP and Modal, would be advantageous.
• Background in streaming data, IoT, or edge computing environments is desirable.
• Experience in a startup-style or otherwise fast-moving business environment is preferred.
• Understanding of how to improve performance in large-scale architectures.
• Familiarity with CI/CD pipelines, testing practices, and deploying software into production.
• Good communication skills and the ability to collaborate effectively across teams.
• Interest in working on advanced systems that combine AI, computer vision, data, machine learning, and real-world applications.
