Original job description

We are looking for highly experienced, hands-on Senior Java Engineers (Architects /Technical Leads with strong hands-on Software Engineering background) to join an innovation-focused on Agentic AI initiatives.

This is a hands-on IC role with significant architectural influence - you'll design the system and write the code. You'll work at the intersection of edge computing, backend services, and AI/ML platforms, collaborating

closely with data science to build the foundation for trust-signal processing and machine learning inference.

What You'll Do

$B!|(B Design and build the end-to-end signal flow: CDN/edge detection -> ingestion APIs -> processing -> sandbox

storage -> downstream routing

$B!|(B Architect edge-layer solutions across edge-worker runtimes and CDN-layer compute for KYA token detection,

header manipulation, and signal capture with minimal latency impact

$B!|(B Build backend services in Java Spring Boot: External Signals Collection API, signal validation/normalization

pipelines, data persistence, and API foundations for the Agentic Trust Service

$B!|(B Define integration patterns for third-party vendor connectivity (KYA providers, identity vendors) including JWT

validation, public-key caching, and deterministic signal ingestion

$B!|(B Ship platform features for ML inference - structured data access layers, feature pipelines, and model-registry

integration points that enable data science to move from exploration to production

$B!|(B Make technology decisions on storage, transport reliability, observability, and governance for non-production

environments on AWS

$B!|(B Operate with startup-like speed - move fast through prototype cycles, demo prep, and iterative architecture

refinement
