Who Are We Looking to Add to Our Team?

As a Senior Project Manager at Massive Rocket, you’ll lead complex, high-value client engagements across multiple workstreams — acting as the primary delivery lead responsible for client success, commercial performance, and delivery excellence.

You’ll operate at the centre of large-scale Martech, CRM, and data programmes, ensuring teams remain aligned, risks are proactively managed, and delivery stays on track across fast-moving environments. Working closely with Programme Leads, delivery teams, and senior client stakeholders, you’ll bring structure, governance, and strategic oversight to every engagement.

This role goes beyond project coordination — you’ll own account-level delivery outcomes, contribute to commercial success, mentor junior team members, and help shape how Massive Rocket delivers scalable, high-quality programmes globally.

• Act as the primary delivery lead for your accounts, ensuring strong client satisfaction and programme performance
• Manage budgets, forecasting, revenue tracking, and margin performance across engagements
• Establish governance frameworks, delivery standards, and reporting structures for large programmes
• Lead RAID management processes, proactively identifying and mitigating risks across workstreams
• Coordinate cross-functional teams across multiple regions and time zones to ensure alignment and delivery momentum
• Facilitate steering committees, programme reviews, stakeholder workshops, and executive-level reporting
• Partner with Programme Leads, delivery teams, and commercial stakeholders to ensure programmes meet both business and operational objectives
• Support RFP responses and contribute to business development activities through delivery planning and estimation
• Mentor and coach junior Project Managers and delivery team members, helping raise delivery standards across the organisation
• Leverage AI tools and automation to improve reporting, project visibility, and operational efficiency

What Makes You a Great Fit

• 5–8 years of Project or Programme Management experience with clear progression in responsibility and complexity
• Proven experience managing complex, high-value, multi-workstream engagements
• Strong commercial management experience, including forecasting, margin management, revenue recognition, and change control
• Excellent stakeholder management skills, with confidence working with senior client stakeholders and navigating complex organisational structures
• Deep understanding of CRM, Braze, Snowflake, and data-driven delivery environments
• Experience working with globally distributed teams across multiple time zones
• Strong governance, planning, and risk management capability across enterprise-level programmes
• Ability to balance delivery quality, commercial performance, and client satisfaction simultaneously
• Experience mentoring or developing junior delivery team members
• Strong communication, escalation management, and organisational skills
• English proficiency at C1 level

Nice to Have
