Our mission is to be the multiplying force that brings together our people, our clients, technology, and data to deliver outcomes others cannot.

The Opportunity

We are hiring a Client & Partner Principal to help lead and grow our UK presence.

This is the most senior client-facing commercial role in the region and a core part of our long-term strategy.

This role is designed for a self-starter. Someone who wants genuine ownership, influence, and trust, not layers of management, sales theatre, or bureaucracy.

You will work closely with a small, highly experienced leadership team and partner directly with senior engineers, architects, and consultants to win and deliver complex enterprise work.

This is a hands-on, relationship-led role for someone who naturally moves between commercial conversations, delivery realities, and executive advisory.

Requirements:
What You’ll Do

Lead and grow Tier 1 enterprise relationships

• Own and grow a portfolio of major enterprise clients as the senior commercial lead and trusted advisor
• Build deep, long-term relationships with CIOs, CTOs, Chief Data Officers, and senior business leaders

Win and shape complex consulting engagements

• Originate and close new client opportunities through consultative, relationship-led selling
• Shape bespoke software engineering, data platform, and AI engagements, often multi-stream and multi-year
• Lead the structuring and signing of complex Statements of Work, including fixed-price and fixed-outcome engagements

Partner closely with delivery and technical leaders

• Work hands-on with senior engineers, architects, and consultants to align scope, pricing, and delivery
• Ensure commercial discipline, margin protection, and delivery realism across engagements

Represent Simple Machines in the market

• Build Simple Machines’ presence across the UK enterprise, data, and AI ecosystem
• Develop relationships with hyperscalers and leading technology partners
• Act as a visible, credible representative of the firm with clients, partners, and industry leaders

Own commercial performance

• Be accountable for pipeline, revenue, margin, utilisation, and long-term account health

Who This Role Is For

This role is for a Senior Client & Partner Principal who is ready to lead.

You bring:

• 10+ years in senior commercial roles within consulting or technology services
• A track record of owning and signing multi-million-pound consulting or engineering engagements
• Direct experience working with Tier 1 enterprises such as banks, telcos, insurers, or similarly complex organisations
• Strong commercial and financial literacy across pricing, margin, utilisation, and forecasting
• Confidence operating directly with senior executives and navigating complex procurement environments
• Tier 1 consultancy-level presentation and communication, with clear executive presence and professional polish

You enjoy autonomy, responsibility, and building things properly. You value quality, judgement, and long-term relationships over volume or noise.
