About Us

Appvia is a cloud-native consultancy and platform provider helping organisations build, secure and scale in the cloud, with offerings such as self-service platforms, governance, cost optimisation and AI accelerators.

Partnering with public cloud providers, we work across the public and private sector to help customers build modern cloud platforms, embed platform engineering best practices, improve governance, and optimise costs to unlock developer velocity and accelerate delivery practices that make cloud a competitive advantage.

As we continue to grow our client base and support increasingly complex transformation programmes, we are hiring a Client Principal / Technical Engagement Manager to take ownership and lead our major strategic accounts and act as the senior bridge between our technical teams and our clients’ senior stakeholders, to ensure value realisation, account growth and delivery.

Interview process - 3 stage

• Discovery conversation with our Talent Acquisition team. 
• Technical Interview deep dive with Head of Solution Architecture. 
• Final Interview with CEO and Hiring Manager.

Important

You must either hold active SC, or be eligible for SC:

• British Passport or ILR
• To have resided in the UK for at least the last 5 years.

About the Role

This is a senior, client-facing engagement leadership role responsible for driving account success, delivery quality, and commercial growth across Appvia's software and data solutions engagements.

You will own the relationship with one or more strategic accounts, leading engagements that solve real business problems through technology, from bespoke software delivery and systems integration to data platforms, analytics, and AI-powered products, and will ensure that Appvia becomes a trusted, long-term strategic partner.

This is a multi-faceted, post-sales role blending technical account leadership, delivery oversight, stakeholder engagement, and commercial ownership. You'll work closely with our CEO, Head of Cloud Solutions, Head of Data & AI, and Head of Software Engineering, ensuring clients see measurable business value from the solutions we build while identifying opportunities to deepen and expand the partnership. This role is also billable and will play a key part in shaping Appvia's future client engagement model and the evolution of a wider Client Solutions function.

Key Requirements

Client relationship & strategic account ownership

• Act as the senior lead contact for the client account: establish, nurture and deepen relationships at executive and senior stakeholder level.
• Understand the client's business drivers, problem space and digital ambitions (revenue growth, operational efficiency, customer experience, data-driven decision-making), and position Appvia's solutions capability accordingly.
• Develop account growth plans: identify and prioritise new opportunities, coordinate with sales/pre-sales, define proposals, and support contract negotiations.
• Monitor health of the account: satisfaction metrics, retention, adoption of delivered solutions, referenceability.

Engagement & delivery oversight

• Oversee the portfolio of solution engagements within the account: ensure governance, appropriate resourcing, milestone adherence, risk/issue management, budget/margin tracking.
• Provide technical oversight: ensure architectural integrity, alignment with best practices, quality of deliverables and alignment to client strategy.
• Shape and validate solution designs with clients: translate business problems into well-scoped software and data solutions with clear success criteria.
• Work with internal teams (engineering/architects, data engineering, consulting, service delivery) to ensure capability and capacity for the account.
• Run customer workshops and discovery sessions to help clients define problems, prioritise use cases, and understand the journey, approach and expectations of adopting bespoke software, data platforms or AI solutions.
• Act as an escalation point for major delivery issues, guiding resolution, and maintaining client confidence.

Growth & value realisation

• Translate technical delivery into business outcomes: e.g., revenue uplift, process automation savings, faster time-to-insight, improved customer experience, better decision-making through data. Use metrics to track value delivered.
• Develop and present value-case updates, account reviews and solution roadmap presentations to client leadership.
• Identify new product/service offerings that match the client's next-phase needs (for example: AI accelerators, intelligent automation, data platform builds, analytics and ML products, application modernisation) and help position them.
• Lead internal lessons-learned and continuous improvement: capture what works in the account, feed improvements back into Appvia's solutions offering.

Internal collaboration & leadership

• Work cross-functionally: with sales/pre-sales, product teams, consulting/engineering, finance, and marketing/referrals to ensure the account's growth and delivery success.
• Mentor more junior engagement/delivery leads within the account (or across accounts) to build a delivery organisation that scales.
• Contribute to Appvia's thought leadership: participate in client workshops, speak at customer events, contribute case studies or white papers (optional but preferred).
