Job Profile

Position details

The AVP, Lead Software Engineer will apply hands-on technical knowledge across data integration, database engineering, scripting, cloud-based data services, and AI-enabled solutions. The role is to help design secure, scalable Generative AI capabilities, including retrieval-augmented generation (RAG), enterprise knowledge bases, semantic search, and document intelligence solutions.

The successful candidate will combine strong engineering fundamentals with analytical thinking, iterative problem-solving, stakeholder management, and a risk-aware approach. The individual will translate business and technical requirements into reliable solutions, guide development teams, and deliver against milestones in a regulated financial-services environment. In the process, you will have exciting opportunities to develop your skills, expand your network, and build your career.

Roles and Responsibilities

· Design, develop, enhance, and maintain complex ETL mappings, workflows, data pipelines, and UNIX/Linux shell scripts in enterprise data warehouse and data lake environments

· Build and optimize batch, real-time, and near-real-time integrations using IDMC or comparable integration technologies

· Develop advanced SQL and database solutions across SQL Server, Oracle, PostgreSQL, or comparable relational platforms, including performance tuning and data-quality controls

· Contribute to dimensional, canonical, and integration data models, and support data warehouses and data marts

· Build reusable Python, Java, or scripting components for data processing, orchestration, validation, automation, and operational support

· Design and build enterprise RAG solutions that retrieve trusted content and provide grounded responses using large language models

· Create and maintain knowledge ingestion pipelines covering document parsing, chunking, metadata enrichment, embedding generation, indexing, retrieval, and citation or source traceability

· Work with vector databases and semantic-search technologies such as Amazon OpenSearch, PostgreSQL with pgvector, or equivalent platforms

· Apply prompt engineering, hybrid search, reranking, context management, and retrieval evaluation techniques to improve answer relevance and reduce unsupported responses

· Build AI-enabled document intelligence solutions for extracting, classifying, summarizing, and validating information from structured and unstructured content

· Establish evaluation approaches for RAG and Generative AI solutions, including retrieval quality, answer groundedness, accuracy, latency, cost, and regression testing

· Implement responsible AI and model-risk controls, including data privacy, access control, content safety, human review, auditability, monitoring, and secure handling of confidential information

· Partner with architecture, security, data governance, model risk, legal/compliance, and business teams to move AI proofs of concept into supportable production services

· Design and support cloud-based data and AI solutions using relevant AWS services such as S3, RDS/Aurora, Redshift, Glue, Athena, Lambda, Step Functions, EventBridge, SQS, Kinesis, EMR, Textract, Bedrock, SageMaker, OpenSearch, IAM, KMS, CloudWatch, and Secrets Manager

· Design and deliver conversational “chat with data” solutions for banking use cases, enabling users to query governed structured and unstructured data through natural-language interfaces with appropriate access controls, source traceability, validation, and safeguards against unsupported responses

· Build resilient, observable, and cost-conscious architectures using infrastructure-as-code, CI/CD, automated testing, logging, metrics, and alerting

· Apply secure cloud engineering patterns for network connectivity, encryption, secrets, least-privilege access, service integration, and operational recovery

· Provide technical knowledge and understandings across design, development, testing, implementation, release, and production-support activities

· Create and review functional designs, detailed technical designs, data mappings, interface specifications, runbooks, and operational documentation

· Gather and document business requirements, assess current technology and processes, and recommend practical target-state solutions

· Coordinate with IT leads, developers, testers, operations, and business stakeholders to ensure deliverables meet functional, non-functional, security, and control expectations

· Participate in production rollouts using change-control processes, clear documentation, stakeholder communication, and implementation validation

· Resolve production defects and incidents within defined service-level expectations; lead root-cause analysis and preventive remediation

· Mentor engineers, promote engineering standards, conduct design and code reviews, and encourage reusable patterns and continuous improvement
