Design for non-functional requirements from day one — availability, recoverability (RTO/RPO), scalability, multi-tenancy, and disaster recovery.
PLATFORM & PIPELINE ENGINEERING
Direct the design and build of scalable batch and streaming pipelines using AWS Glue, Amazon EMR, Amazon Kinesis, Amazon MSK, and AWS Lambda.
Model and optimise analytical data stores in Amazon Redshift and S3-based data lakes — partitioning strategy, file formats, compaction, distribution and sort keys, workload management.
Set the standards for CDC and ingestion patterns from operational databases and SaaS sources using AWS DMS, Glue connectors, and Kinesis.
Own orchestration patterns across Amazon MWAA, AWS Step Functions, and Amazon EventBridge, including idempotency, retry, backfill, and SLA-breach handling.
Own data cataloguing, lineage, and fine-grained access control via AWS Glue Data Catalog and AWS Lake Formation.
Define the data quality and observability framework — contracts, expectations, freshness and volume checks, reconciliation, and alerting.
PERFORMANCE TUNING & COST OPTIMISATION
Lead deep performance engineering across Redshift, Athena, Spark on EMR/Glue, and streaming workloads: query plan analysis, skew and spill remediation, partition pruning, caching, concurrency scaling, and shuffle optimisation.
Establish benchmarking and profiling practice — define baselines, instrument workloads, and drive measurable improvements in latency, throughput, and job runtime.
Own the FinOps posture for the data estate: right-sizing, Spot and Graviton adoption, storage tiering and lifecycle policies, Redshift RA3/serverless sizing, and per-workload cost attribution and chargeback.
Set and enforce cost and performance SLOs, and run regular optimisation reviews with engineering and finance stakeholders.
ENGINEERING STANDARDS & CODE REVIEW
Define and enforce engineering standards: coding conventions, repository structure, branching strategy, testing pyramid, documentation, and definition of done.
Act as final reviewer and approver on critical pull requests; run structured code review sessions and raise the review bar across the team.
Own CI/CD for data pipelines — automated testing (unit, integration, data quality), linting, security scanning, environment promotion, and release management.
Champion infrastructure as code (Terraform, AWS CDK, or CloudFormation) and reusable, modular, well-tested platform components over bespoke one-off builds.
Drive technical debt visibility and remediation planning alongside feature delivery.
TEAM LEADERSHIP & MENTORING
Lead and technically line-manage a team of data engineers across multiple squads; allocate work, set technical goals, and own delivery quality.
Mentor and coach senior and mid-level engineers; run design clinics, brown-bag sessions, and structured upskilling and certification paths.
Contribute to hiring — technical screening, interview panel design, and calibration of the evaluation bar.
Provide input to performance reviews, career development conversations, and succession planning for key technical roles.
Build a culture of ownership, documentation, and blameless post-incident learning.
STAKEHOLDER MANAGEMENT & COMMUNICATION
Act as the senior technical point of contact for customer architects, data leaders, and business sponsors; translate business objectives into technical roadmaps and vice versa.
Present architecture, trade-offs, risks, and cost implications to both engineering audiences and CxO-level stakeholders with equal clarity.
Manage expectations on scope, sequencing, and delivery risk; escalate early with options rather than problems.
Support pre-sales and solutioning — effort estimation, technical proposals, solution walkthroughs, and proof-of-concept design.
Partner with analysts, data scientists, and product owners to shape production-grade, consumable data products.
GOVERNANCE, SECURITY & COMPLIANCE
Embed security controls into every pipeline — encryption at rest and in transit, KMS key management, IAM least privilege, VPC and network isolation, secrets management.
Own PII discovery, classification, masking, tokenisation, and retention patterns; ensure designs meet applicable regulatory obligations (India DPDP Act 2023, GDPR where relevant) and audit requirements under ISO 27001 and SOC 2.
Define data governance operating model in partnership with security and compliance functions — data ownership, access request workflows, and audit logging via AWS CloudTrail and Lake Formation.
