Job Description

ABOUT JSM

At JSM Group, we are a leading specialist infrastructure engineering company. We design and install the complex power networks, digital infrastructure and specialist systems a future-focused worldwide marketplace needs — from high-power grid connections to critical utilities, data centres to renewable energy.

From High-Power grid connections to Critical Utilities. Data Centres to Renewable Energy, our full turnkey solution teams manage the full scope to help advise and deliver complex infrastructure projects at speed, on time and with reduced legislation, technical and commercial risks.

ABOUT THE TEAM

You'll join our People and Culture team, reporting to the Chief People Officer, and own reward decisions across the whole organisation — using JSM's job architecture, job families, career pathways and grading as your foundation.

Day to day, you'll work closely with People Operations on data and systems, Finance on reward budgeting and forecasting, and line managers across our engineering, infrastructure and construction business who come to you with pay, offer and grading queries.

ABOUT THE ROLE

As Compensation & Benefits Manager, you'll own how JSM rewards its people across all locations, from pay structures and job grading through to benefits design and pay review governance. Reporting to our Chief People Officer, you'll make sure reward decisions across our organisation are fair, market-competitive and consistent, using JSM's job architecture, job families, career pathways and grading as your foundation.

Day to day, you will:

Pay, Grading & Job Architecture

• Own the day-to-day application of JSM's job architecture, evaluating new and changed roles against the Job Family, Career Pathway and Grade framework, and recommending grading outcomes to the CPO
• Review job profile assignment requests (new hire and promotion) coming through the approval process, checking grading consistency before they're entered into HiBob
• Design and maintain JSM's salary structures and pay ranges, benchmarking roles against relevant market data for the engineering, infrastructure and construction sectors
• Lead job evaluation exercises for new or significantly changed roles, working with People and Culture colleagues and line managers

Reward Cycles & Governance

• Plan and run the annual pay review and bonus/incentive cycle end-to-end, including budget modelling, manager guidance and system updates
• Prepare gender pay gap reporting, equal pay audits and other statutory reward reporting, flagging risks and recommending corrective action
• Maintain reward policies and governance documentation, keeping them aligned to employment law and JSM's Great Place to Work commitments

Benefits

• Own JSM's employee benefits offering — pension, health and wellbeing, and lifestyle benefits — including provider relationships, renewals and procurement
• Review and refresh the benefits package periodically to keep it competitive, cost-effective and genuinely valued by employees
• Lead clear, accessible communication of pay and benefits to employees and managers

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.

ENGINEERED TO BELONG

At JSM Group, we're not just shaping the future of utilities, we're raising the bar for what a great place to work looks like.

Our values aren't words on a wall. They drive every decision we make and every project we take on, pushing us to go further, do better, and leave a real mark on the industry.

We want people who are hungry to grow, ready to take on complex challenges, and excited to work alongside clients and partners who are changing the landscape of the utility sector across the UK, Europe and beyond.

In return, we give you the room to develop fast, the work to stretch you, and the platform to build a career that actually means something — and here's what that looks like in practice:

WHAT WE OFFER

In addition to an industry competitive salary, we offer:

• Performance-linked bonus, where applicable
• Pension — 4% employer matched
• Generous annual leave plus bank holidays
• Health cash plan (BUPA) — cashback on dental, optical and physiotherapy
• Healthcare plan (Benenden Health) — faster medical advice, private diagnostics and treatment alongside the NHS
• Employee assistance programme
• Electric car scheme — lease a fully maintained EV through salary sacrifice
• Funded training and development through our Training Centre and Competency Cloud, professional membership and a clear route to chartership or higher authorisation

We're committed to making our recruitment process accessible. If you need an adjustment at any stage — to the application, the interview format or the assessment — tell us and we'll sort it. Every application is assessed on skills, experience and potential.
