Job Description

Role Summary

As a lead software engineer, you are accountable for shaping and delivering end-to-end solutions for enterprise-grade platforms and complex initiatives. You set technical direction, define and govern architecture, and lead delivery execution for a specific solution area while influencing adjacent domains. You operate confidently across diverse cloud environments, applying deep knowledge of cloud infrastructure, architecture patterns, and engineering practices to design solutions that scale securely and reliably across enterprise platforms. You are hands-on and outcome-driven: designing and building critical path components, raising engineering standards, and scaling team effectiveness through mentorship, patterns, and automation.

You partner closely with Architecture, Security, Infrastructure, and Product to ensure solutions are resilient, secure-by-design, scalable, observable, and compliant with enterprise standards. You also pioneer responsible AI-assisted engineering by establishing guardrails, validations, and governance that enable speed without compromising quality.

This opportunity is with the Enterprise Data Management Office (EDMO), where you will deliver Data Catalog services as a product, driving enterprise-wide data discovery, governance, and self-service access to trusted data assets.

Key Outcomes

• An end-to-end technical solution is delivered predictably with strong SDLC discipline, from design to build, test, deploy and operate.

• Architecture decisions are documented, traceable and aligned with enterprise standards; trade-offs are explicit and risk-managed

• Cloud architecture and infrastructure decisions support scalable, resilient, secure and cost-effective platform growth across diverse deployment environments

• Engineering quality improves quarter-over-quarter through standards, automation and coaching across security, performance and maintainability

• Production stability is strong, with high availability, clear SLOs / SLAs, fast incident recovery and actionable observability

• Teams ship faster with confidence due to reusable patterns, platform capabilities and AI-enabled workflows with robust guardrails.

Customer

• Lead end-to-end solution architecture and delivery: define solution options, align cross-functional stakeholders, own execution and ensure production readiness for complex systems.

• Drive hands-on engineering and modernization: deliver critical components, resolve bottlenecks and implement target-state architecture with incremental, de-risked migration strategies.

• Ensure resilient, scalable and efficient platforms: define and validate NFRs, automate delivery, manage dependencies and continuously improve performance, availability and cost efficiency.

• Lead cloud architecture and engineering decisions across diverse cloud environments, selecting scalable infrastructure patterns, deployment models and integration approaches that align with enterprise standards.

AI Workflow Innovation & Governance

• Champion AI-assisted development using modern copilots and LLM agents to accelerate delivery while maintaining enterprise-grade standards.

• Design and roll out AI guardrails, including approved use cases, prompt patterns, code provenance expectations and documentation standards.

• Implement validation pipelines for AI-generated code, including linting / formatting, unit and integration tests, SAST / DAST, dependency scanning, secret detection and architectural rules.

• Define human-in-the-loop review requirements, including code review checklists, threat modelling and design reviews for high-risk changes.

• Establish a repeatable AI workflow for the team, including task decomposition, generation, verification, refactoring and documentation, and measure cycle-time impact.

• Promote responsible use across privacy, data handling, IP considerations, auditability and compliance with internal policies and external regulations.

Shareholder

• Ensure governance, compliance and risk alignment: adhere to enterprise frameworks, drive approvals and manage policies in line with business priorities and risk appetite.

• Drive quality and operational excellence: enforce shift-left quality, lead design and code reviews, and oversee release readiness and operational gating.

• Optimize performance and efficiency: lead enterprise-level analysis, drive remediation and continuous improvement, reduce costs through FinOps practices and integrate emerging trends and regulatory needs.

Employee / Team

• Scale team impact through enablement: establish patterns, reference implementations, documentation and coaching over individual heroics.

• Mentor and elevate engineering excellence: provide hands-on technical guidance, unblock complex issues, lead knowledge sharing through RFCs, guilds and reviews, and drive continuous learning.

• Foster a high-performing, inclusive team: promote quality, innovation and collaboration; communicate risks proactively; support hiring, onboarding and equitable practices.

Breadth & Depth

• Acts as a primary subject matter expert across multiple technical areas from design, support and solutions perspectives.

• Works independently and / or autonomously as a senior lead across a diverse range of complex tasks and operational support of solutions.

• Foresees issues and gaps, identifies emerging industry trends and translates them into practical engineering direction.

• Generally reports to a Senior Manager, Engineering.

Qualifications & Technical Requirements

• Exceptional problem-solving skills with a proven track record diagnosing complex system failures and designing resilient solutions.

• Strong hands-on experience designing normalized, extensible relational data models, including schemas, entities, relationships, keys, constraints, historical/versioned data, and models that can accommodate multiple source structures.

• Knowledge Graph & Graph Database Engineering: Hands-on experience designing and implementing knowledge graph or graph-oriented data models, including nodes, edges, relationship semantics, graph traversal and query patterns, and integrating graph capabilities with PostgreSQL or graph database technologies to support connected-data discovery, lineage, dependency mapping and impact analysis.

• Strong hands-on experience with PostgreSQL, SQL, Python and data engineering, including database schemas, indexing, query optimization, JSON/JSONB where appropriate, transformations, change tracking, and high-volume data processing.

• Proven experience designing and developing reusable ingestion and extraction patterns using REST/Graph APIs, batch/file processing, Kafka/event-driven integration, and incremental processing. Strong understanding of SQL versus NoSQL trade-offs.

• Ability to contribute hands-on to the design and implementation of a data lake, including raw, standardized/ normalized, curated/ consumption layers that can scale for future sources and use
