Job description

What you’ll do

• Act as a trusted technical advisor to customers and internal teams on high-value implementations and expansions, shaping integration approaches, system configuration, and overall solution design.
• Partner with activation / onboarding and account management teams to translate customer requirements into scalable architectures, particularly where ERP, HRIS, and API integrations are core to the rollout.
• Work with sales teams on technical discovery to understand customer systems, data flows, and workflows, and recommend a best-fit integration blueprint, including when and how to leverage APIs and third-party connectors.
• Work hands‑on with customers to troubleshoot integration hurdles and guide them through complex configuration decisions, focusing on designing robust, maintainable implementations rather than writing code directly.
• Serve as a subject matter expert on the broader integration ecosystem (e.g. HRIS and accounting partners), collaborating with Sales, Product, and partners to close gaps and improve integration coverage.
• Create and maintain internal documentation, playbooks, and lightweight tooling that make it easier for the wider team to support integration-heavy use cases at scale.
• Channel customer pain points and integration feedback into Product and Engineering, influencing the roadmap and prioritisation of features that materially improve implementation outcomes.

Who you are

We’re looking for people who meet the minimum requirements for this role. The preferred qualifications are great to have, but are not mandatory.

Minimum qualifications

• Bachelor’s degree in a related field (e.g. Business, Finance, Engineering, Information Systems) or equivalent practical experience.
• 5+ years of experience in implementation, onboarding, customer success, or project/program management, managing complex, multi‑stakeholder technology or financial services implementations.
• 4+ years of client‑facing delivery or professional services experience in a high‑paced environment (e.g. SaaS, fintech, consulting, systems integration, enterprise implementation).
• Proven track record of successfully delivering cross‑functional projects with stakeholders from diverse backgrounds and job functions, including C‑level executives, technical teams, and operations.
• Exceptional written and verbal communication and presentation skills, including the ability to lead steering meetings, write clear status updates, and influence decisions without direct authority.
• Experience delivering ERP, accounting system, or expense platforms (e.g. Netsuite, SAP, Oracle, Xero) implementations and the associated data flows (GL, cost centres, entities, card feeds).

Preferred qualifications

• Hands‑on experience working with or alongside integration engineers, solution architects, or technical program managers on API‑based integrations, including familiarity with common web, SSO, and ERP integration concepts.
• Formal training or certification in project management or agile delivery (e.g. PMP, PRINCE2, Scrum Master), and comfort setting up operating rhythms such as stand‑ups, steering committees, and executive readouts.
• Experience managing strategic or enterprise accounts as part of a broader account team, including navigating commercial sensitivities while protecting delivery quality and scope.
• Ability to thrive in a fast‑moving, ambiguous environment, balancing structured methodologies with pragmatic decision‑making to keep complex projects moving forward.
