Senior Project Manager Energy Infrastructure

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.

Our full turnkey solution teams manage the full scope to help advise and deliver complex infrastructure projects at speed, on time and with reduced legislative, technical and commercial risk.

JSM is now growing its presence in Germany and across Europe, building on a stable and profitable UK parent company to establish a new German and European delivery organisation.

ABOUT THE TEAM

Our German and European business is entering an exciting phase of growth. The Portfolio Manager will work closely with senior leadership, Project Managers, Commercial and Finance teams, as well as colleagues across our UK and European operations.

You will play a key role in building the structure, governance and capabilities needed to support JSM's continued growth in Germany and the wider European market.

ABOUT THE ROLE

The Portfolio Manager is responsible for the overall performance of JSM's German and European project portfolio. The role exists to bring governance, visibility and commercial discipline to a fast-growing portfolio, and to build the structure and capability the business needs as it scales.

Day to day, you will:

• Set portfolio and resource priorities, milestones and performance measures, and report performance, risks and recommendations to the CEO Germany

• Oversee delivery of multiple projects against programme, budget, quality, safety and contractual requirements

• Challenge plans, forecasts and variances with Project Managers, and drive corrective action

• Deliver and improve portfolio revenue, margin, cost, cash flow and forecast with Commercial and Finance

• Identify and manage commercial risks and opportunities, and support contract and variation management

• Build senior client relationships and act as the escalation point for major issues

• Identify growth opportunities and contribute to bid and tender strategy

• Lead and develop Project Managers, share lessons learned, and support the mobilisation of new projects

• Participate directly in the current large construction project to build sector and market knowledge — potentially taking it over as it moves towards completion, if timing allows

ABOUT YOU

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

• You combine strategic thinking with strong delivery and commercial focus

• You'd rather build the structure, governance and processes a growing organisation needs than manage one that's already set

• You build trusted relationships with senior clients and work confidently across German, UK and European teams

• You work in a structured way under deadline pressure, and you write convincingly in both German and English

• You spot gaps early and act on them before they affect delivery

• You bring an operational, hands-on, entrepreneurial mindset, and you embrace JSM's values — integrity, respect, continuous improvement, accountability, diversity & inclusion and team spirit

EXPERIENCE

Essential

• 3+ years' experience in portfolio, programme or senior project management within infrastructure, construction, engineering, utilities, energy or a related sector

• Experience managing multiple complex projects simultaneously

• Strong commercial understanding: budgets, forecasting, margins, risk and contractual performance

• Senior client and stakeholder relationship management

• Experience leading project teams and influencing across functions

• Project governance, risk and performance management

• Excellent organisational, team-building and decision-making skills

• German and English language skills, C1 or above

Desirable

• High-voltage power infrastructure, substations, grid connections or civil engineering experience

• A degree in engineering (MSc Electrical, Mechanical or Civil Engineering)

• Experience in data centre, renewable energy or electrical infrastructure projects

• Civil engineering, major construction or EPC/turnkey delivery experience

• Knowledge of the German energy or infrastructure market

• PRINCE2, PMP or IPMA (Level B or equivalent) qualification

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.

WHAT WE OFFER

In addition to an industry-competitive salary, this role offers:

• The chance to shape your own processes, team and ways of working from the ground up, backed by a stable and profitable UK parent company

• Genuine influence over JSM's long-term German and European growth strategy, with direct exposure to senior leadership

• Hybrid working

• Work on live data centre and renewable energy projects

• A clear path to a leadership role — potentially Operations Director or Head of Delivery — within 2–3 years as the business grows

• Funded training and development, including support towards IPMA or PMI certification

DIVERSITY, INCLUSION & EQUAL OPPORTUNITIES

JSM Group is an equal opportunities employer. We're building teams that reflect the communities and clients we work for, and we believe better engineering comes from bringing different experience into the same room.
