• Drive technical transformation through hands‑on prototyping, emerging tech adoption and architectural modernization

Cloud & Platform Excellence

• Design and deliver cloud‑native Kubernetes‑based solutions with deep AWS expertise
• Monitor and optimize cloud expenditure using FinOps practices
• Lead initiatives for platform reliability, performance and infrastructure cost management
• Support multi‑cloud strategies and evaluate new cloud services where appropriate

• Create proofs‑of‑concept for evaluating and integrating new technologies
• Stay proficient in multiple programming languages (TypeScript, Python preferred; Go a strong bonus)
• Contribute to on‑call rotations for critical production systems

Qualifications

Experience & Leadership

• 10 years of progressive experience in software architecture including several at a senior / principal level
• Demonstrated ability to influence and shape architectural direction at organizational scale
• Proven track record leading technical transformation initiatives
• Strong leadership and mentoring skills with the ability to inspire without direct authority

Technical Expertise Cloud & Infrastructure

• Deep expertise in AWS and Kubernetes essential for success in this role
• Experience with multiple cloud vendors and multi‑cloud approaches
• Strong DevOps / CI‑CD background with hands‑on experience in Terraform
• Familiarity with cloud cost optimization frameworks and FinOps practices

Technical Expertise Architecture & Development

• Expertise in modern architectural patterns: microservices, hexagonal, DDD, bounded contexts and event‑driven approaches represented
• Familiarity with enterprise architectural frameworks (e.g. TOGAF, Zachman) and practical application
• Strong programming background (TypeScript or Python preferred; Go a strong bonus)
• Experience building high‑scale distributed systems and services

Experience expressing system designs with C4 Modeling

• Knowledge of relational, NoSQL and search databases (PostgreSQL, MySQL, MongoDB, Elasticsearch) and messaging systems (RabbitMQ, Kafka, NATS)
• Proficiency in continuous delivery deployment pipelines and automated testing practices

Essential Soft Skills

• Exceptional communicator able to simplify complexity for different audiences
• Trusted mentor and role model with a lead‑by‑example approach
• Adaptable and resilient in fast‑changing ambiguous environments
• Collaborative, detail‑oriented and passionate about continuous learning
