## About the Role

Do you have experience in APIs?, * 8+ years of experience designing and owning end-to-end data and application architectures across distributed systems (services, APIs, data flows, infrastructure), with a deep understanding of runtime behavior, scalability, latency, and failure modes in production environments.

 * Proven expertise in system integration and API design, defining clean, robust interaction models across heterogeneous and externally developed components.
 * Experience evolving and hardening existing systems - bringing architectural clarity, structure, and scalability to complex or partially defined environments.
 * Experience designing systems in high-security, compliance-heavy contexts (e.g., defense, aerospace, critical infrastructure), where security and reliability are core architectural constraints.
 * Ability to review, challenge, and enforce architectural standards across engineering teams and external partners - grounded in real technical depth and practical system-building experience.

## Description

This is a core product engineering role with architectural authority across internal teams and subcontractors. You will define and govern the end-to-end system architecture - from ingestion and processing to APIs and user-facing applications - ensuring scalability, security, performance, and long-term maintainability in a mission-critical environment.

Within 3 months, you will review and take over management of the existing data & application architecture (including security model, integration standards, and UI principles), ensuring this is formally adopted by all subcontractors and internal stakeholders., * Within 3 months, you will review and take over management of the existing data & application architecture (including security model, integration standards, and UI principles), ensuring this is formally adopted by all subcontractors and internal stakeholders.

 * Define system boundaries, interaction models, and integration standards across internal components and external partners.
 * Make and defend architectural decisions impacting scalability, performance, resilience, and long-term maintainability.
 * Set clear technical direction for service communication patterns, data flows, and interface design.
 * Ensure security-by-design at architectural level, aligned with high-assurance operational environments.
 * Provide technical governance across internal teams and subcontractors - including design reviews, architectural approvals, and enforcement of standards.
 * Ensure alignment between system architecture and operational user workflows, delivering reliable, actionable mission insight.
