Develop, test, deploy, and operate backend services for authentication, authorization, and identity management. Work across the full SDLC, maintain reliability and scalability, collaborate with product/architecture/SRE teams, and use automated tests, CI/CD pipelines, and cloud-native tooling to deliver secure identity solutions.

Lead design and ownership of shared libraries, Spring Boot starters, and agentic frameworks. Set standards for agent orchestration, evaluations, and guardrails. Mentor teams on Python-based agents (LangChain/LangGraph), drive adoption, prototype research directions, and improve developer experience across Kotlin backend and client libraries.

Lead design and implementation of enterprise identity and access: SSO (OIDC/SAML), RBAC with query-time enforcement, SCIM provisioning, token exchange/on-behalf-of flows, service accounts, entitlements, session and token governance to enable secure, auditable access at scale.

Develop and maintain mobile app and no-code quest editor, implement gameplay engine and server, design software architecture, and collaborate in one-week Scrum sprints using C++, Qt, QML, MySQL, and AI-assisted tools.

Build and maintain scalable automated test frameworks and suites for a message-driven, distributed collateral exchange platform. Develop functional, integration, and non-functional tests; create stubs, simulators, and test harnesses; integrate tests into CI/CD; collaborate with Java/Kotlin developers, DevOps, and external counterparties to validate resilience, security, and confidentiality in a regulated fintech environment.

Design, own, scale, and iterate data processing pipelines for Mapbox Roads. Implement new pipelines, monitor performance metrics, and enforce security best practices. Collaborate in a cross-functional team to build navigation and high-definition mapping features.

Own architecture and long-term direction of the classification and discovery layer: correlate telemetry into graph topologies, perform entity resolution and deduplication, associate metrics/logs to entities, and drive a streaming-first topology materialization with Memgraph and Kafka.

Own and improve the durable execution engine for AI agents: runtime, scheduling, checkpointing, resumption, and recovery. Ensure correctness, reliability, and scalability under load; enable integrations with orchestration frameworks, agent harnesses, and model capabilities.

Design and implement scalable compute-platform services for workload placement. Build microservices (Flask, gRPC, SQLAlchemy), deploy with Docker/Kubernetes, write unit tests, integrate open-source solutions, optimize performance, perform algorithmic analysis and root-cause investigations, and produce well-documented Python code.

Design, build, and maintain Cloud Manager web UI and corresponding backend services. Implement new features and bug fixes, write unit tests, integrate open-source components, and improve internal processes. Collaborate in an agile team using TypeScript, React, Python, Flask, SQLAlchemy, REST APIs, and Docker.
