The Position:  

Due to business growth, we’re looking for a Principal and Senior Drainage & Infrastructure Engineer to join our multi-disciplinary team in Basingstoke or Bristol. Reporting to the Associate leading the discipline, the Senior & Principal Engineer will oversee drainage and infrastructure design for multiple UK projects, supporting engineers and technicians on schemes ranging from small domestic works to £20m developments. Our projects span commercial, public sector, rail, domestic, and temporary works, offering variety and the chance to broaden your expertise. 

Some of the main responsibilities of the Principal and Senior Drainage & Infrastructure Engineer will include: 

• Lead on the design of civil engineering and infrastructure projects, managing the full life-cycle of your own project workload - including drainage design, highways design, and related works for residential, commercial, education, and leisure developments. 
• Provide technical guidance and support to colleagues, helping them develop practical, high-quality solutions. 
• Build strong client relationships, taking full ownership of liaison throughout delivery to confirm scope and deliverables, while identifying opportunities to secure and maximise future work.

• Conduct inspections, site surveys, and technical assessments, producing detailed reports to inform design and project delivery. 
• Review, check, and approve designs produced by others, providing feedback and ensuring technical excellence. 
• Lead the preparation of tenders and fee proposals to support business growth. 

In either role, you’ll take ownership of projects from proposal to completion - working closely with clients, leading design, and supporting the team to deliver practical, innovative solutions. At Principal level, you’ll also manage other engineers and contribute towards their professional growth; the Senior Engineer will work independently on their own projects and support colleagues, with opportunities to step into leadership. 

• Proficiency in Causeway Flow or MicroDrainage (Causeway Flow preferred). 
• Skilled in AutoCAD Civil 3D, with proven experience in drainage design for residential, commercial, or other relevant building projects. 
• Knowledge of flood risk assessments and planning support. 
• For the Principal level: proven experience leading and developing a team. 
• Ideally Chartered (ICE) or working towards it. 
• Sector experience in planning support and drainage design is preferred, but applicants with building or broader infrastructure backgrounds are welcome. 
• A client-focused approach, with strong interpersonal and communication skills. 
• Full UK driving licence and own transport. 
• Fluency in English language and the permanent right to work in the UK, alongside UK project experience.
