Join Us in Engineering Resilient Infrastructure for a Sustainable Future
At RPS Tetra Tech, we’re shaping the next generation of transport infrastructure across Ireland and the UK. As a Senior Drainage Engineer, you’ll play a pivotal role in delivering innovative, standards‑led drainage solutions that enhance resilience and sustainability. From leading complex design packages to integrating cutting‑edge digital workflows and climate adaptation strategies, this is your opportunity to influence major projects, mentor emerging talent, and drive excellence in multidisciplinary collaboration. If you’re passionate about technical leadership and making a lasting impact on the future of transport, we’d love to hear from you.
Purpose & Scope of the Role
The Senior Drainage Engineer provides technical leadership within the Transport and Civils Drainage team, taking responsibility for the end‑to‑end delivery of drainage design across a diverse portfolio of projects in Ireland and the UK. This role ensures that designs, calculations, models, and documentation meet programme, technical, and quality requirements, align with Irish and UK standards, and satisfy client expectations. You will lead drainage workstreams, coordinate with project managers, discipline leads, clients, and regulators, and resolve technical interfaces to deliver resilient, constructible, and cost‑effective solutions. The position also includes mentoring junior engineers, contributing to resource planning, and producing high‑quality design packages, reports, and integrated 3D models that support approvals and consents.
Your Impact in this Position
In this role, you will lead and deliver drainage design packages on live civil and transport projects, stabilising and accelerating delivery while contributing to climate adaptation strategies for the Irish national road network. You will integrate emerging technologies, including AI, to improve efficiency and design assurance. Over time, you will take ownership of new projects through the full lifecycle—from inception and option development to detailed design, construction support, and handover—while embedding the latest standards and innovations in drainage design. Longer term, you will have the opportunity to progress into senior leadership, shaping strategy, strengthening client relationships, and contributing to a sustained track record of successfully delivered programmes across Tetra Tech RPS.
