About the Role

The Senior Software Engineer plays a key role in designing and building new customer-facing applications and APIs that sit at the heart of our product offering. 

The role works across the full stack, with a focus on building robust backend services and modern, responsive front-end experiences. 

Key Responsibilities

Backend Development 

• Design, build and maintain scalable backend services and RESTful/GraphQL APIs using Python (Django or FastAPI). 

• Write clean, well-tested, production-grade code with a focus on reliability and performance. 

• Design and implement data models, working with relational databases (PostgreSQL) and cloud-native data services. 

• Build and maintain CI/CD pipelines, ensuring automated testing, linting and deployment as standard. 

Frontend Development 

• Build modern, responsive user interfaces using React (TypeScript), delivering polished user experiences. 

• Collaborate with product and design to translate requirements and wireframes into functional, accessible UI components. 

• Ensure frontend performance, accessibility and cross-browser compatibility. 

Platform & Infrastructure 

• Work within a cloud-native environment on Microsoft Azure, contributing to infrastructure decisions and service architecture. 

• Contribute to observability, monitoring and alerting for production services. 

• Participate in incident response and root cause analysis when issues arise. 

Collaboration & Ownership 

• Take ownership of features end-to-end, from technical design through to delivery and iteration. 

• Participate actively in code reviews, architectural discussions, and sprint ceremonies. 

Skills & Experience

Essential 

• Significant professional experience (typically 5+ years) in software engineering, with a strong track record of delivering production systems.

Desirable 

• Experience with data engineering concepts: ETL/ELT pipelines, data modelling, or working with data platforms (e.g. Databricks, Azure Data Factory). 

• Familiarity with event-driven architectures, message queues (e.g. Kafka, Azure Service Bus) or streaming data. 

• Experience working with scientific, geospatial or time-series data. 

• Exposure to infrastructure as code (Terraform) or platform engineering practices.
