Compensation & Benefits Manager (Part-time)

Data, Systems & Compliance

• Maintain the accuracy and integrity of compensation data in HiBob, partnering with People Operations on data quality
• Produce reward MI and analytics for the CPO and senior leadership — pay ratios, cost of reward, benchmarking insight and pay review outcomes
• Ensure pay practices comply with National Minimum/Living Wage, Equal Pay Act and other relevant location-specific employment legislation

Advisory & Stakeholder Management

• Advise line managers and people team colleagues on pay decisions, offers and grading queries
• Partner with Finance on reward budgeting and forecasting
• Act as JSM's internal subject matter expert on compensation and benefits, supporting wider People and Culture projects as needed

This is a part-time role (21 hours a week), based at our Head Office in Potters Bar, built around real flexibility for how you structure your working pattern, with full ownership of JSM's reward agenda.

ABOUT YOU

You'll do well here if you recognise yourself in this:

• You're hungry to grow and you take personal responsibility for your work and your development.
• You're comfortable with complexity and you'd rather solve a hard technical problem than avoid it.
• You work well across disciplines — you know good delivery depends on civil, power and digital teams pulling in the same direction.
• You use sound judgment under pressure and you're straight with people about risk and programme.
• You can manage the structure and pace of a pay review or bonus cycle independently, and you're comfortable owning JSM's reward agenda within a part-time working pattern.

How you'll show up

We assess success in this role against JSM's five behaviours:

• Technical Excellence & Problem Solving — You bring rigour to job evaluation and pay analysis, spotting anomalies and building reward models people trust.
• Communication & Collaboration — You translate technical reward concepts into plain language for managers and employees, and work closely with People Operations, Finance and business leaders.
• Delivery & Accountability — You own the pay review and bonus cycle end-to-end, hitting deadlines and keeping governance tight.
• Leadership & People Development — You guide managers to make fair, consistent reward decisions, and help build reward capability across the People and Culture team.
• Commercial Awareness — You understand the cost and budget impact of every reward decision, balancing competitiveness with commercial reality.

EXPERIENCE

Essential

• Proven experience in a compensation & benefits, reward, or job evaluation role
• Hands-on experience with a job evaluation methodology (e.g. Hay, Mercer, Willis Towers Watson, or an equivalent framework), and running market benchmarking exercises
• Strong Excel and data analysis skills, comfortable building and interpreting pay models and reward MI
• Working knowledge of UK employment law as it relates to pay, equal pay, National Minimum/Living Wage, and gender pay gap reporting
• Experience using an HRIS (HiBob or equivalent) to manage compensation data
• Strong stakeholder management skills, able to explain reward decisions clearly to managers and employees at all levels

Desirable

• Experience in engineering, construction, or infrastructure sectors
• Experience designing or embedding a job architecture / job family framework
• Pension scheme and employee benefits procurement experience

REQUIREMENTS & QUALIFICATIONS

Desirable

• CIPD qualification, or GRP (Global Remuneration Professional) or equivalent reward accreditation

If you meet most but not all of the above, we'd still like to hear from you. We'll look at what you've delivered and what you're capable of, not just the list.
