About the role
We are looking for a senior Solution Architect who will also act as Tech Lead, responsible for end-to-end architecture, from applications to cloud infrastructure and for the technical leadership of the team in delivering the project. This person will combine architectural vision, hands-on work, and team leadership: defining the architecture of solutions and applications, guiding and developing the engineering team, and being accountable for delivery with quality, on time, and within the defined technical standards.

Responsibilities
Architecture
• Define the software architecture of solutions and applications (domain modeling, service decomposition, API contracts, and integration patterns) as well as the cloud infrastructure architecture.
• Design distributed systems architectures with high availability, scalability, and fault tolerance.
• Define and document end-to-end solutions on AWS, considering cost, security, performance, and operability (pillars of the AWS Well-Architected Framework).
• Architect serverless solutions with AWS Lambda (Python), including orchestration patterns, idempotency, and event handling.
• Model the data layer on RDS PostgreSQL (schemas, performance, scalability, integrity).
• Guide the architecture of front-end applications in Angular integrated via AWS AppSync (GraphQL).
• Lead the design of solutions and agents based on Kiro and Anthropic models (agent orchestration, prompts/context, guardrails, and quality evaluation).
• Drive architecture decisions (ADRs), technical trade-offs, and design reviews.

Technical leadership & delivery (Tech Lead)
• Technically lead the engineering team, being responsible for delivering the project with quality and on schedule.
• Translate the architecture into an execution plan, breaking work into incremental deliverables and prioritizing the technical backlog together with Product/PM.
• Define and uphold quality standards: code review, testing, CI/CD, observability, and engineering best practices.
• Mentor developers, support the team's technical growth, and act as an escalation point for complex challenges.
• Remove technical impediments, coordinate dependencies, and communicate status, risks, and trade-offs to leadership and stakeholders.
• Balance delivery pragmatism with long-term technical health (technical debt management).
• Ensure security, governance, and compliance (IAM, encryption, networking, compliance).

Required qualifications
• 10+ years of experience in distributed systems architecture.
• 5+ years of experience in AWS solution design.
• Proven experience in software/application architecture (systems design, microservices, event-driven architecture, APIs) not just infrastructure.
• Experience as a Tech Lead or in technical leadership of teams, with accountability for project delivery.
• AWS certifications (Solutions Architect Associate and/or Professional, Developer, SysOps Administrator, DevOps Engineer, etc.).
• In-depth knowledge of scalability, resilience, observability, and disaster recovery.
• Experience with cloud security (IAM, networking, encryption, governance).
• Strong communication, organizational, and influencing skills with engineering teams, leadership, and stakeholders.
• Experience in agile environments (Scrum/Kanban) and DevOps/SRE culture (CI/CD, automation, FinOps).
• English at C1 or C2 level, with experience in international projects.

Nice to have
• Experience with generative AI / agent-based solutions, including RAG, agent orchestration, and evaluation.

Soft skills
• Technical leadership, mentoring, and the ability to develop people.
• Systems thinking and long-term vision.
• Ability to balance technical, delivery, and business trade-offs.
• Strong communication and cross-team collaboration.
• Results-oriented with a strong sense of ownership over delivery.
