Lead modernization efforts for core APIs and platform interfaces that support AI-native workflows and automated consumers.
Define and drive company-wide standards for AI-ready APIs, including deterministic behavior, schema consistency, validation, observability, versioning, and operational safeguards.
Refactor and evolve legacy systems to support structured machine consumption, orchestration layers, MCP integrations, and scalable agent workflows.
Identify and resolve API inconsistencies such as non-standard error handling, hidden side effects, ambiguous data models, and weak contract enforcement.
Design backend systems and APIs capable of supporting high-concurrency automated traffic patterns, orchestration loops, and resilient distributed workflows.
Establish architectural guardrails including idempotency protections, advanced rate controls, validation strategies, authorization patterns, and failure containment mechanisms.
Partner with AI orchestration teams, platform engineering, and domain engineering organizations to enable scalable integration patterns across ABC’s ecosystem.
Provide technical leadership and architectural guidance across multiple engineering organizations while helping shape long-term modernization strategy.
Lead design reviews, mentor senior engineers, and help elevate engineering standards and architectural maturity across the company.
Develop pragmatic modernization strategies that balance ideal future-state architecture with operational realities, production constraints, and incremental delivery goals.
Drive alignment between platform architecture, API strategy, and AI enablement initiatives across the organization without disrupting existing product and operational roadmaps.
Not building isolated greenfield services that do not connect to core business systems.
Not a traditional feature-delivery role focused primarily on frontend or UI-driven requirements.
Not incremental bug fixing — this is a strategic modernization and re-architecting effort focused on core platform interfaces and machine interoperability.
Typically 10+ years of software engineering experience with deep expertise in backend systems, distributed architectures, and platform engineering.
Demonstrated success architecting, building, and evolving complex APIs and distributed systems at scale.
Proven experience modernizing legacy platforms and mission-critical production systems without disrupting business operations.
Deep understanding of API contracts, schema design, deterministic behavior, observability, validation, versioning, authentication, authorization, and integration reliability.
Strong systems-thinking mindset with the ability to understand platform-wide architectural implications and downstream effects on AI agents and orchestration systems.
Experience driving technical strategy and influencing architectural direction across multiple teams and organizations.
Strong engineering fundamentals across resiliency, scalability, performance, operational excellence, and distributed systems design.
Ability to operate as a senior technical leader and subject matter expert within a complex engineering organization.
Experience mentoring senior engineers and leading architectural discussions that improve platform quality and long-term maintainability.
Pragmatic decision-making skills with the ability to balance strategic architecture goals with delivery timelines and existing system constraints.
Strong collaboration skills and a One Team mindset across platform, infrastructure, AI, and product engineering organizations.
Experience with gRPC, Protocol Buffers, GraphQL, or other strongly typed API frameworks.
Familiarity with Model Context Protocol (MCP), AI orchestration systems, or building structured interfaces for LLM-powered tools and agents.
Experience with event-driven architectures, workflow orchestration systems, and high-throughput distributed platforms.
Experience establishing engineering standards, platform governance models, or enterprise-wide modernization initiatives.
Experience designing highly observable systems with advanced traffic management, resiliency, and operational safeguards.
Experience supporting AI-native product architectures or machine-driven integration ecosystems.
Core APIs are highly predictable, reliable, and scalable for both application teams and automated AI consumers.
AI orchestration teams can integrate new agents and workflows with minimal custom integration logic or workaround layers.
Platform standards for AI-ready APIs are clearly defined, practical to adopt, and consistently implemented across engineering organizations.
Core systems remain stable, secure, and performant under increasing levels of automated and concurrent machine-driven traffic.
Engineering teams have clear paved-path architectural guidance for building and evolving APIs that support long-term AI strategy.
Modernization initiatives improve platform quality, reduce integration complexity, and accelerate AI capability delivery across ABC.
The organization has a sustainable architectural foundation capable of supporting future AI-native platform evolution.
ABC Fitness is building toward an AI-native future where intelligent agents, orchestration systems, and automation platforms can securely and reliably interact with our products and services at scale. The effectiveness of those systems depends on the quality, predictability, and reliability of the APIs that power them.
You are not simply modernizing APIs — you are helping build the operational foundation that allows AI systems to safely and effectively interact with ABC’s products, workflows, and data ecosystem at scale.
