Hybrid Working

Are you a talented Senior Bid Writer ready to take the next step in your career — and looking for an employer who will actively invest in helping you get there?

At SMS Environmental, we're offering the chance to join our growing business in a role designed to develop you into a future Bid Manager. If you're ambitious, motivated, and eager to progress, this is the perfect next move.

SMS Environmental is a leading provider of water hygiene, water treatment, and facilities management services across the UK. We help clients maintain safe, compliant, and efficient environments — and we're expanding fast.

What makes this role exciting

  • A genuine development pathway to Bid Manager
  • Hands-on coaching, mentoring, and support from experts in the field
  • The opportunity to gradually take on more strategic and commercial responsibility
  • A role where your work directly supports the company's growth
  • A collaborative, friendly team that wants you to thrive
  • You will manage and mentor a junior Bid Writer 

What you'll be doing

As a Senior Bid Writer, you'll take ownership of producing high-quality, persuasive, and commercially aligned bid submissions — while gradually stepping into the leadership, commercial, and strategic aspects of full bid management.

Your responsibilities will include:

Bid Writing & Coordination

  • Producing compelling, clear, and compliant bid responses
  • Coordinating inputs from technical, operational, compliance, finance, and sales teams
  • Ensuring accuracy, consistency, and high quality across all submissions

Supporting Bid Management

  • Assisting in planning and coordinating the full bid lifecycle
  • Taking an active role in bid/no-bid discussions
  • Helping maintain the tender pipeline and documentation
  • Supporting the development of bid tools, templates, and best practices

Developing Commercial & Strategic Skills

  • Learning how to develop pricing strategies with guidance from the commercial team
  • Contributing to executive summaries, win themes, and value propositions
  • Supporting reviews, lessons learned, and continuous improvement activities

As you grow, you'll take on more responsibility for leading bids, shaping strategy, and eventually overseeing the process end-to-end.

What you'll bring

You'll be an experienced Senior Bid Writer (or a Bid Writer ready for that step up) with:

  • Strong bid writing and editing abilities
  • Experience working on tenders or proposals, ideally in water hygiene, legionella control, or FM (not essential)
  • Excellent organisation and coordination skills
  • Stakeholder management confidence
  • Understanding of the UK bid lifecycle and procurement processes
  • Curiosity, ambition, and a desire to develop into a Bid Manager
  • Proficiency with Google Workspace and bid management tools

Most importantly, you'll bring the ambition to grow — and the drive to take on more responsibility over time.

What you'll enjoy

  • A clear development path to Bid Manager with dedicated support
  • A collaborative, growing business where your work makes a visible impact
  • 22 days' holiday plus bank holidays (plus your birthday after two years)
  • Private Medical Care or Cash Plan (after two years)
  • Enhanced Sick, Maternity, and Paternity Leave
  • 24/7 Employee Assistance Programme
  • Staff discount scheme (worth up to £240 per month)
  • Quarterly Core Values Champions Rewards
  • Hybrid working (up to two days from home) after six-month on-site probation
  • A modern, supportive working environment in Harwell
