Define non-functional requirements for availability, performance, concurrency, security, privacy, observability, disaster recovery, and supportability.
Review designs and code, identify technical risks, challenge assumptions, and drive pragmatic decisions that balance quality, time, and cost.
Establish engineering standards, reusable patterns, quality gates, documentation expectations, and technology adoption guidance.
Lead technical discovery, proof-of-concept work, platform assessments, modernization planning,

Deep understanding of API-first design, event-driven architecture, messaging, distributed systems, and cloud-native engineering.
Experience with Postgre SQL or comparable relational databases, data modeling, integration data flows, and transactional design.
Hands-on experience with contact center or Customer Experience platforms and the operational concepts behind customer routing and engagement.
Excellent English communication skills, including the ability to produce clear technical documentation and lead client-facing workshops.
