Software Eng Tech Lead

Description We are looking for a Tech Lead to own the technical direction of a squad within the Trintech AI Platform — either the Agent Stream or the Platform Team . You own how the squad designs and builds — running design sessions, making squad-level technical trade-offs, and translating the Software Architect’s direction into squad execution. You remain hands-on in code and design, but your primary accountability is the technical soundness of everything the squad ships, not just your own services. What You’ll Do Squad Technical Leadership Own squad technical direction — run design sessions before implementation, challenge proposals, and ensure services are designed correctly before code is written. Primary technical interface between the Software Architect and the squad — translate architectural direction into squad-level implementation decisions across all services. Review and challenge low-level designs from squad engineers — identify design debt, scalability risks, and contract inconsistencies before they reach production. Own squad-level technical standards — API contract conventions, observability patterns, test architecture, and code quality bar across all squad services. Identify systemic quality issues across the squad — patterns of technical debt, repeated design mistakes, and coverage gaps that affect collective delivery quality. Hands-On Engineering Delivery Own and deliver the most technically complex service implementations in the squad. Review critical PRs with depth and set the engineering standard through example. Own CI/CD pipeline integration, observability instrumentation, and production-readiness gates for squad services. System Design Lead squad-level high-level design sessions — cross-service interaction patterns, failure modes, and data contracts across service boundaries. Make system design trade-off decisions independently — latency vs. consistency, synchronous vs. event-driven, shared vs. isolated data models. Proactively flag architectural risks — scalability bottlenecks, failure cascade risks, and integration complexity in squad designs before they affect delivery. Technical Mentorship Mentor Principal and Senior Engineers — design reviews as learning sessions, actionable technical feedback, deliberate capability building across the squad. Make design reasoning visible and transferable — the squad’s technical level rises because the Tech Lead explains why, not just what. Who You Are Python Backend Engineering — Primary Gate 10+ years in software engineering with primary depth in Python backend systems — FastAPI, async patterns, service design, error handling, and observability at production scale. Low-level system design at lead depth — designs and reviews components, data structures, service internals, and API contracts from first principles. Applies the same rigour to others’ designs as to their own. System Design — Primary Gate High-level system design at working depth —…
