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 - cross-service interaction patterns, failure modes, and data contracts. Leads squad design sessions and makes trade-off decisions independently.
• Distributed systems depth - failure modes, scalability trade-offs, consistency vs. availability, and graceful degradation for shared platform services.

Technical Depth

• Event-driven architecture - message ordering, delivery guarantees, idempotency, and failure handling. Designs and reviews event-driven services with equal depth.
• Multi-tenant data architecture - tenant isolation, data partitioning, row-level security, and cross-tenant boundary enforcement.
• Immutable data design and append-only event patterns - owns at design review level, not just implementation.
• API design and OpenAPI contracts - designs, versions, and governs platform APIs. Contract consistency across squad services is a Tech Lead ownership item.
• SQL and NoSQL at production scale - schema design, query optimisation, indexing, and data modelling trade-offs across service boundaries.
• Kubernetes, Docker, and Helm - production deployment, release engineering, and squad-level CI/CD pipeline ownership.

Awareness

• Security and IAM patterns - OAuth flows and token propagation at service level. Sufficient to identify security gaps in squad designs and escalate to the Platform Architect.
• API gateway and platform integration - how squad services are exposed through the platform layer. LLM and agent service patterns: sufficient to design service interfaces that agent consumers can build against.

Nice to Have

• Workflow orchestration - Temporal or equivalent. AI-native SDLC: Human-led Agentic SDLC practices.
• Azure cloud experience. Experience building audit, compliance, or billing platform capabilities.

What You’ll Learn & Gain

• Squad-level technical ownership on a live enterprise AI platform - design decisions and technical standards that shape the quality of every service the squad ships.
• System design depth accelerated by owning cross-service decisions, running design reviews, and making trade-off calls that service-level IC roles rarely require.
• Technical leadership as a senior IC - growing Principal and Senior Engineers through design review and mentorship, with clear paths toward Staff Engineer, Architect, or Engineering Manager in the Bangalore market.
• Direct collaboration with the Software Architect and Engineering Manager in a fast-moving, squad-based delivery model where technical decisions have immediate, visible production consequences.

If you are a senior engineer ready to own squad technical direction, lead design sessions with confidence, and grow from service-level into system-level technical leadership - we encourage you to apply.
