The Role
We are seeking a Senior Backend Engineer to play a pivotal role in the evolution of our reporting and analytics platform. This critical project involves rearchitecting our existing system to leverage a modern reporting paradigm and introduce technologies that will allow us to scale reporting to large data sets (300 million data points per customer). As a senior engineer, you will play a key role in designing scalable data pipelines, implementing pre-calculation strategies, and enabling dynamic custom reporting capabilities for our clients.
This position requires a blend of deep technical expertise, strategic vision, and hands-on engineering skills to ensure the successful delivery of this architecture transformation. You’ll collaborate with product managers, engineers, data engineers, data scientists and stakeholders to create a robust, high-performing solution that meets our customers’ evolving reporting needs.

What you'll be responsible for

• Driving Architectural Design: Design, build, and maintain a reporting platform that integrates with high volume database technologies (TSDB/OLAP) and provides custom BI capabilities, ensuring scalability, performance, and reliability.
• Develop and Optimise Data Pipelines: Create data transformation pipelines to summarise and pre-calculate large volumes of data for efficient querying and reporting.
• Ensure High Standards of Quality: Maintain robust testing and CI/CD pipelines, write high-quality and secure code, and implement QA best practices.
• Solve Complex Problems: Confidently debug and optimise complex issues across services, data pipelines, and the stack.
• Technical Leadership: Provide architectural direction, make pragmatic decisions on technical trade-offs, and mentor team members.
• Stakeholder Collaboration: Work closely with the product team to define, refine, and deliver user stories that translate into impactful reporting features.

Experience and skills we look for

• Proven Experience in Data-Intensive Systems: Strong track record in designing and building reporting systems, including data pipelines, TSDB/OLAP, or similar architectures.
• Expertise in Backend Development: Experience building APIs and services, preferably in Ruby, but open to other languages with the ability to quickly learn new ones.
• Data Engineering Knowledge: Familiarity with ETL pipelines, data modelling, and pre-aggregation techniques to handle large datasets.
• Analytical Thinking: Ability to debug, optimise, and solve problems across complex systems and services.
• CI/CD and Testing: Deep understanding of CI/CD pipelines and testing frameworks to ensure the reliable delivery of high-quality software.
• Leadership and Collaboration: Experience guiding technical projects, mentoring engineers, and collaborating across teams.

Additional Skills that set you apart

• Experience with time-series databases (e.g., Amazon Timestream, InfluxDB, TimescaleDB) or scalable analytics platforms.
• Knowledge of business intelligence tools (e.g., Power BI, Tableau, or Looker) for custom report development.
• Hands-on experience with AWS services for data processing and secure storage, particularly in GovCloud or IL5-compliant environments.
• Familiarity with AI/ML tools and workflows, particularly in the context of data analytics and reporting.
• Strong understanding of database optimisation, caching strategies, and performance tuning.
