Core Responsibilities

Primary Functions

  • Own the technical vision and architecture for major product areas: define and document scalable, maintainable architectures, make trade-off decisions, and ensure alignment with company strategy and engineering roadmaps.
  • Lead the end-to-end design and delivery of complex features and platform capabilities, coordinating multiple squads and external partners to meet product and business goals.
  • Write and review high-impact production code, coding standards, and design documentation to ensure high-quality, secure, and maintainable implementations.
  • Drive adoption of cloud-native patterns, microservices, serverless, and container orchestration (Kubernetes) to enable resilient, autoscaling production systems.
  • Define and enforce API contracts, versioning strategies, backward compatibility, and developer experience for internal and external services.
  • Own performance, reliability, and scalability targets for systems — lead capacity planning, load testing, and performance tuning to meet SLAs and SLOs.
  • Establish and evolve CI/CD pipelines, automated testing strategies (unit, integration, e2e), and release practices to accelerate safe delivery and reduce lead time for changes.
  • Lead incident response and postmortem processes for high-severity outages: coordinate remediation, root-cause analysis, and long-term fixes to prevent recurrence.
  • Mentor, coach, and develop senior and mid-level engineers: run technical 1:1s, help with career plans, set technical goals, and lead technical interviews and hiring decisions.
  • Translate product requirements into technical plans and work with Product Managers to scope work, set priorities, and balance short-term delivery with long-term technical health.
  • Drive technical debt reduction and refactoring efforts while prioritizing investments that improve velocity, reliability, and maintainability.
  • Collaborate with security, privacy, and compliance teams to ensure systems meet regulatory requirements, secure coding guidelines, and data protection standards.
  • Instrument systems with observability (metrics, logs, traces) and set up dashboards and alerts for proactive monitoring and business KPI visibility.
  • Lead cross-functional architecture reviews and design forums: gather feedback, foster consensus, and document architecture decisions (ADR) and rationales.
  • Evaluate, select, and integrate third-party technologies, libraries, and vendor solutions, balancing cost, risk, and long-term maintainability.
  • Implement cost-optimization strategies for cloud infrastructure including right-sizing, autoscaling policies, and infrastructure-as-code governance.
  • Champion modern development practices such as test-driven development, feature flags, blue/green and canary deployments, and service meshes where appropriate.
  • Drive data-driven engineering by defining metrics, tracking delivery KPIs, and using telemetry to prioritize engineering investments and improvements.
  • Manage roadmaps for technical initiatives — break large projects into milestones, track dependencies, and communicate progress and risks to stakeholders and executives.
  • Facilitate knowledge sharing across teams: run design reviews, tech talks, runbooks, and internal training sessions to upskill the organization.
  • Ensure robust data architecture, storage design, and query performance for both OLTP and OLAP needs; collaborate with data engineers and analysts on schemas, ETL, and event-driven architectures.
  • Serve as a key technical liaison with Product, Design, Sales, and Customer Success on customer escalations, feature feasibility, and high-impact POCs.
  • Define and measure engineering quality metrics (code quality, test coverage, deployment frequency, MTTR) and lead continuous improvement initiatives based on these metrics.
  • Build and enforce standardized development workflows, branching strategies, and contribution guidelines to ensure predictable, auditable releases.
  • Create a healthy team culture that encourages psychological safety, inclusive decision-making, feedback, and continuous learning.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.

Required Skills & Competencies
