Role:

As a Senior Software Engineer at Previsico, you will be a key technical leader within the engineering team, driving the design, delivery, and evolution of our flood forecasting and prevention systems. You will take ownership of complex, high-impact projects across teams or domain areas, ensuring that our systems are scalable, reliable, and secure.

You will act as both a technical leader and mentor, helping to set direction for engineering best practices, influencing architectural decisions, and supporting less-experienced developers in their growth.

This role demands deep technical expertise, strategic thinking, and strong communication skills to bridge technical and non-technical domains effectively.

Key Responsibilities:

• Lead the technical design, development, and delivery of complex features and systems with significant business impact.

• Drive architectural decisions that balance performance, scalability, maintainability, and business value.

• Own end-to-end project lifecycles, from concept to deployment, ensuring successful delivery of high-quality solutions.

• Mentor, coach, and support other engineers, fostering technical growth and continuous improvement across the team.

• Collaborate cross-functionally with Product, Science, Operations, and Design to shape roadmaps and deliver impactful outcomes.

• Lead system refactoring and optimisation initiatives, managing technical debt pragmatically and promoting long-term system health.

• Ensure high observability and resilience through monitoring, alerting, and proactive issue prevention.

• Contribute to and influence technical strategy within your team or domain, linking engineering priorities to business objectives.

• Represent engineering in external discussions when required, communicating complex ideas clearly and credibly.

• Champion engineering culture, promoting best practices in accessibility, performance, testability, and security.
