About the Role
As the most senior member in our Customer Engineering organization, you will provide white-glove, deeply technical, and highly strategic support to Aircall's most valuable strategic and enterprise customers, driving value from your very first day. This role brings together advanced technical capability, consultative depth and commercial impact. Staff CEs work closely with CTOs, Heads of CX, Heads of Digital and operational leaders inside customer organizations. They ensure complex deployments, integrations and AI adoption programs are executed successfully and become drivers of long-term retention and growth.
Responsibilities
- Own onboarding for large, high-complexity customers (250+ employees, 100+ users), leading deep discovery, mapping business processes, designing advanced workflows and integrations, and driving technical implementation to a smooth, timely, high-quality go-live.
- Act as the day-to-day technical counterpart to Key Account Managers, working 1:1 or 1:2 to deliver a unified commercial and technical approach across technical strategy, risk assessment, renewal readiness, integration roadmaps, and adoption plans.
- Run quarterly and mid-cycle technical reviews for strategic accounts (covering renewal readiness, ROI articulation, workflow optimization, and integration stability), and help KAMs surface expansion and retention opportunities backed by technical outcomes.
- Deploy and optimize advanced AI add-ons like AI Assist Pro and AI Voice/Messaging Agent optimization, building customer-specific AI adoption playbooks and becoming a regional expert in AI-enabled workflows.
- Serve as the technical architect and owner for advanced configurations, challenging integrations, and custom workflow builds, coordinating closely with Engineering, Product, and internal technical experts to deliver bespoke solutions.
- Review product telemetry, integration performance, and usage patterns to anticipate issues before they surface, and lead root-cause analysis on the most complex product or integration issues.
- Coordinate high-impact escalations end-to-end, driving internal alignment, providing technical direction, leading communication, and maintaining executive trust through to clear resolution.
- Identify recurring technical themes and capability gaps from strategic accounts to inform the product roadmap, mentor CEs and Scaled CEs, and elevate the technical craft across the organization.
Requirements
- Strong command of VoIP fundamentals, APIs, integrations, webhooks, data flows, authentication models, cloud architectures, and customer tech stacks.
- Ability to read and interpret code (JavaScript, Python, or similar).

- Able to speak confidently with CTOs, CIOs, Heads of CX, and Operations leaders, translating technical strategy into clear business terms.
- Sound judgment for triaging a large portfolio where touching every account every quarter is not realistic.
- Able to prioritize time and effort against north star metrics, focusing energy on the accounts and actions that move the needle most.
- Proven ability to lead multi-stakeholder, multi-phase technical projects with predictable delivery and clear communication.
- Clear understanding of how technical decisions affect renewal, GRR, NRR, and expansion, with the ability to influence commercial strategy through technical insight.
- A strong sense of ownership over your portfolio and its outcomes, taking personal accountability for retention, churn mitigation, and contraction / GRR performance across your strategic accounts.
- Maintains confidence and clarity during escalations, high-stakes conversations, and strategic customer interactions.
- Effective collaborator with Engineering, Product, Support, KAMs, and FDEs, able to translate customer needs into structured internal actions.
- Professional proficiency in German and English is required.
- 8+ years of experience in Customer Engineering, Solutions Engineering, Technical Consulting, or Technical Account Management in SaaS.
- Strong background in complex implementations, technical onboarding, and solution deployment for mid-market or enterprise customers.
- Hands-on experience with APIs, integration design, low-code platforms, or light coding.
- Prior hands-on experience designing, implementing, or supporting agentic AI workflows, including voice and messaging agents, is strongly preferred.
- Proven success supporting strategic accounts, renewals, and expansions, with direct impact on NRR/GRR outcomes.
- Experience working directly with senior customer stakeholders including CTOs, CIOs, technical leads, or operations executives.
- Demonstrated ability to operate as a senior individual contributor with high autonomy, strong judgment, and technical leadership.
- Demonstrated proficiency with AI-powered productivity tools and large language models (such as ChatGPT or Claude), including their practical application in day-to-day work.
- Background in telephony, communications, contact center, AI, or workflow-heavy SaaS is a strong advantage.
- Professional proficiency in a third language (Spanish or French) is a strong plus.
