Solution Architect (AWS, AI, Python)

Job Description

• Role Overview

  We are seeking a highly experienced Senior Solution Architect  to lead the design and delivery of enterprise-grade, secure, and scalable cloud-native solutions. This role sits at the intersection of AI strategy, data engineering, and platform architecture  within a highly regulated environment. You will be instrumental in shaping the technical direction of next-generation AI and data platforms, from early-stage proof of concepts through to production-grade architectures.

• Key Responsibilities

• Cloud Architecture & Solution Design

• Design, validate, and prove complex end-to-end cloud architectures on AWS , spanning batch processing, real-time streaming, and event-driven patterns.
• Architect solutions leveraging AWS services including EC2, S3, Lambda, SNS, SQS, Kinesis, AWS Glue, Athena, Redshift, and EMR/EMR Serverless .
• Lead the design of Data Warehouse  and Data Lake  solutions, ensuring scalability, performance, and cost efficiency.
• Define and govern architectural frameworks, patterns, and reusable design blueprints for use across engineering teams.

• AI Strategy & Generative AI

• Define and drive the organisation's AI strategy , aligning AI initiatives with broader business and technology goals.
• Architect and deliver Generative AI (GenAI)  solutions, including LLM integration, prompt engineering patterns, and AI-powered application design.
• Design, build, and deploy MCP (Model Context Protocol) servers and AI Agents , covering the full lifecycle from development to production deployment on AWS.

• Data Engineering & Pipeline Design

• Design and deliver robust end-to-end data pipeline architectures , encompassing both batch processing  (AWS Glue, Athena, EMR) and real-time streaming  (Kinesis/Kafka, SQS/SNS).
• Architect solutions using NoSQL databases  including Amazon DynamoDB  and MongoDB , selecting appropriate data storage patterns based on access patterns and scale.
• Apply best practices in data modelling , partitioning, and query optimisation across relational, NoSQL, and warehouse layers.

• Security, Compliance & Governance

• Ensure all solutions adhere to enterprise security, compliance, and governance frameworks  within a highly regulated industry.
• Integrate Veracode  and other SAST/DAST tooling into the development lifecycle to proactively identify and remediate security vulnerabilities.
• Design and implement data encryption  strategies at rest and in transit, leveraging AWS KMS, TLS/SSL , and secrets management tools (AWS Secrets Manager, Parameter Store).
• Apply secure-by-design principles across all architectural decisions, including API security, identity federation, and zero-trust networking.
• Maintain deep understanding of communication protocols  (REST, GraphQL, gRPC) to make informed integration and interoperability decisions.

• Engineering Excellence & POC Delivery

• Lead significant Proof of Concept (POC)  and Proof of Value (POV)  engagements, validating architectural approaches and emerging technologies ahead of production commitment.
• Operate comfortably across the full developer lifecycle  — authoring requirements, documenting architectural patterns, writing production-quality code, defining tests, and deploying to cloud environments.
• Champion DevOps and automation  practices including CI/CD pipeline design, Infrastructure as Code (IaC) using Terraform or AWS CDK, and observability/monitoring frameworks.
• Collaborate closely with development teams, third-party suppliers, and product stakeholders to ensure alignment with architectural principles and delivery objectives.
• Implement robust authentication and authorisation mechanisms  for MCPs, AI Agents, and APIs, ensuring compliance with enterprise security standards (OAuth 2.0, API Gateway policies, IAM roles).
• Evaluate and recommend AI frameworks, agent orchestration tools, and emerging GenAI technologies to continuously advance platform capability.

Qualifications

• Proven experience as a Senior Solution Architect  or equivalent in a large-scale, regulated enterprise environment.
• Deep hands-on expertise with AWS  (EC2, S3, Lambda, Glue, Athena, Kinesis, SNS, SQS, Redshift, DynamoDB, API Gateway, IAM, KMS).
• Demonstrated experience designing and deploying AI/ML and GenAI applications  on AWS.
• Hands-on experience building and deploying MCP servers and AI Agents , with a strong understanding of agent orchestration patterns and tool-use protocols.
• Strong knowledge of API authentication and security  — OAuth 2.0, OpenID Connect, JWT, API Gateway authorisers, mTLS.
• Experience designing batch and streaming data pipelines  at enterprise scale.
• Working knowledge of NoSQL databases  (DynamoDB, MongoDB) and Data Warehouse  technologies (Redshift, Snowflake, or equivalent).
• Familiarity with Veracode  or equivalent security vulnerability scanning tools integrated into CI/CD pipelines.
• Strong understanding of data encryption  principles, key management, and compliance-driven data handling.
• Proficiency with IaC tools  (Terraform, AWS CDK, or CloudFormation) and CI/CD platforms (Jenkins, GitHub Actions, or equivalent).

• Nice to Have

• Experience with multi-agent frameworks  (LangGraph, AutoGen, CrewAI, or similar).
• Knowledge of data mesh  or data fabric  architectural patterns.
• Familiarity with vector databases  (Pinecone, OpenSearch, pgvector) for RAG-based AI architectures.
• AWS certifications (Solutions Architect Professional, Data Engineer, or AI/ML Specialty).
