Job Description:

About the Role

Are you a technically fearless engineer-leader who sees AI not as a buzzword but as a *different way of thinking* — one that reshapes how teams design, build, and deliver software? Do you thrive at the intersection of architecture, data, and human-centered product delivery?

As Tech Lead (TL) embedded in a high-performing, cross-functional delivery squad at TD, you will be the technical heartbeat of the team — defining architecture, setting engineering standards, mentoring engineers, and being the first voice in the room when a new feature touches system integration, security, or data — all while championing an AI-native mindset that continuously pushes the team to work smarter, not just harder.

This is not a purely hands-off role. You write code, you review PRs, you pair with engineers on hard problems, and you represent the team's technical voice in planning ceremonies and cross-team dependency conversations.

Key Accountabilities

Solution Architecture & Technical Leadership

• Serve as the Solution Architect / Tech Lead (SA/TL) for the delivery squad — the final technical authority for all design decisions within the team
• Design and own end-to-end system architecture including API contracts, service/repository layers, data models, and integration patterns between Go backend, React frontend, and PostgreSQL
• Lead architecture reviews at the start of every new feature involving system integration, new components, or external dependencies — before a single line of code is written
• Produce architectural artifacts: sequence diagrams, component diagrams, ADRs (Architecture Decision Records), and API specifications
• Evaluate and articulate trade-offs between competing architectural approaches, balancing velocity, maintainability, security, and cost
• Define and enforce coding standards, branching strategies, and CI/CD pipeline quality gates across the team

AI-First Thinking & Innovation

• Champion an AI-native engineering culture — not just tooling adoption, but a fundamentally different problem-solving approach: using AI to augment requirements analysis, code generation, test automation, anomaly detection, and decision support
• Leverage large language models and generative AI APIs to build intelligent features — including natural language query interfaces, intelligent summarization, and document understanding pipelines
• Integrate AI-powered developer tooling into the team's SDLC to accelerate delivery without sacrificing quality
• Prototype and evaluate LLM-based solutions for business problems; present build-vs-buy-vs-integrate recommendations to stakeholders
• Continuously scan the AI landscape and bring forward concrete, scoped proposals for how emerging capabilities can be applied to the product domain

Google Cloud Platform (GCP) Engineering

• Design and operate cloud-native workloads on Google Kubernetes Engine (GKE) — including cluster configuration, workload autoscaling, resource quotas, and deployment strategies
• Architect data storage and retrieval solutions using Google Cloud Storage (GCS), including lifecycle policies, IAM bindings, and integration patterns with backend services
• Build and maintain BigQuery data pipelines and reporting views for analytics and executive dashboards
• Leverage Cloud Run, Pub/Sub, Cloud Scheduler, and Secret Manager to build event-driven, serverless-adjacent features where appropriate
• Manage infrastructure as code using Terraform for GCP resource provisioning and environment parity across dev/staging/prod

Security & Compliance

• Collaborate with the Security / BISO role on any feature involving authentication, authorization, sensitive data, financial data, or external integrations — security review is mandatory before release

• Validate authentication/authorization implementations against TD security standards and OWASP Top 10

• Ensure all AI/ML integrations comply with TD's responsible AI framework and data residency requirements

Agile Delivery & Cross-Team Collaboration

• Participate actively in SAFe delivery ceremonies — PI Planning, System Demos, Inspect & Adapt — as the technical representative for the team
• Identify and surface cross-team technical dependencies to the Release Train Engineer (RTE) early; co-own resolution
• Partner with the Product Owner (PO) before development starts on any feature or epic to ensure technical feasibility, effort accuracy, and risk visibility
• Work with the Business Analyst (BA/BSA) to decompose requirements into technically sound, testable stories with clear acceptance criteria
• Mentor and grow engineers within the team through pairing, code review, design critique, and knowledge-sharing sessions
• Prioritize and manage own workload to deliver quality results on sprint timelines while unblocking teammates

Critical Skills and Qualifications

Must Havehat We're Looking For

Backend Engineering -Go (Golang) — handlers, middleware, REST API design, service/repository patterns

Frontend Engineering -React + TypeScript, state management, REST API integration

Data Engineering -SQL, PostgreSQL, data modeling (ERD, dimensional), ETL/ELT design

Cloud — GCP -GKE, GCS, BigQuery, Cloud Run, IAM, Secret Manager, Terraform

AI / ML -LLM integration patterns, RAG, prompt engineering, embedding models, generative AI APIs

Architecture -System design, API contracts, ADRs, sequence/component diagrams

Agile / SAFe -PI Planning, cross-team dependency management, story refinement

AI Mindset

We are not looking for someone who has taken an AI certification course. We are looking for someone who:

•Thinks differently because of AI — approaches problems by asking "what if we didn't have to code this?" or "what if the system could reason about this itself?"

•Has shipped at least one AI-powered feature into production and learned hard lessons from it

•Can evaluate AI claims critically — knows when a model is hallucinating, understands latency/cost trade-offs, and can right-size AI involvement to the actual problem

•Brings concrete proposals, not abstractions — "here is an AI-powered feature we could ship in Sprint 3" vs. "we should leverage AI"

Experience and Education

• Undergraduate degree in Computer Science, Software Engineering, or equivalent technical discipline
• 7+ years of relevant software engineering experience, with at least 3 years in a tech lead or architect capacity
• Demonstrated experience designing and shipping production systems on Google Cloud Platform
• Hands-on experience integrating LLM/generative AI APIs into production applications
• Preferred: experience with Databricks and PySpark at enterprise scale
• Preferred: experience in financial services or regulated industries (data governance, audit trails, compliance requirements)
