We believe great work begins with great people. That’s why our culture is built on respect, trust, and belonging. We create an inclusive environment where every team member can bring their authentic self to work—because diverse perspectives drive innovation and meaningful impact.

Growth Mindset

We are doers, thinkers, and dreamers. At ABC Fitness, your growth is our investment. Through continuous learning, mentorship, and professional development opportunities, we empower you to reach new heights—personally and professionally.

One Team

From day one, you’ll be part of a team that collaborates, celebrates, and cares. We move fast, support one another, and have fun along the way. Because when you thrive, we all thrive.

What You'll Do 

Lead the service transformation teams 

Build and manage small, high-ownership squads responsible for converging duplicated product capabilities into shared, domain-oriented services. Own the delivery cadence, quality, and predictability of a multi-year transformation executed in steady quarterly increments with clear boundaries, owners, and cutover plans. 

Turn architecture into shipped services 

Partner with principal engineers and staff engineers to translate target architecture, service boundaries, migration seams, and compatibility strategies into sequenced, executable plans your teams can implement safely. Your job is to make the architecture real: prioritized, staffed, de-risked, and delivered. 

Establish the base service tier 

Drive the standards for how shared services are designed, contracted, versioned, documented, and consumed, so that every ABC application — and the AI agents and partners building on top of them — can rely on one consistent capability layer. Ensure services are designed for both human and machine consumption from day one, with structured contracts that agents can use reliably. 

Protect compatibility and business continuity 

Convergence only counts if customers never feel it. Lead teams through incremental strangler-style migrations, staged cutovers, dual-running periods, and post-cutover hypercare. Existing behavior, reporting, and integrations keep working until each consumer has safely moved. 

Modernize the application foundations 

Guide the movement of business logic out of legacy, database-centric implementations into testable, cloud-native services on our target stack. Retire duplicated builds, legacy dependencies, and aging infrastructure as consumers cut over. 

Raise the bar for engineering quality 

Build quality in as a system, not a stage. Establish a software-factory approach where every change moves through automated validation loops — layered validators for scope, contracts, parity, runtime behavior, and user experience — that produce evidence of correctness rather than claims of completion. Design the pipeline so that failures are detected, diagnosed, and corrected in-loop before work integrates, and so that each converged service ships with a durable, inspectable evidence trail. The goal is simple: ship quality software, quickly. 

Drive AI-native ways of working 

Enable your engineers to use AI across code comprehension, design exploration, implementation, migration analysis, test generation, and documentation. Turn promising individual uses into repeatable team practices, so a small squad can credibly take on a portfolio-scale transformation. 

Make AI the way your team works: engineers direct agents across code comprehension, design exploration, implementation, migration analysis, test generation, and documentation, and the factory's validation gates — not manual inspection — prove every change correct. Turn what works into repeatable factory practices, so a small squad can credibly take on a portfolio-scale transformation. 

Hire and grow strong engineers 

Recruit, coach, and develop engineers who are comfortable working across legacy code and modern service design. Set clear expectations, give honest feedback, and build a culture of ownership, craft, and follow-through. 

Partner across the program 

Work closely with product, program leadership, principal engineering, SRE, security, and data teams to sequence domains by customer impact and technical dependency, surface risk early, and keep cross-team commitments visible and managed. 

What This Is Not 

This is not an architecture-only or people-only role. You are expected to engage credibly with design and delivery detail, challenge weak technical assumptions, and be accountable for outcomes — while your engineers own the code. 

This is not a greenfield platform build. The value of this work is measured by safely converging live, revenue-critical systems onto shared services, not by producing new frameworks. Decisions must balance long-term platform quality with migration safety, business value, and the realities of changing production applications. 

This is not a big-bang rebuild or a customer migration program. The transformation is evolutionary: systems stay releasable throughout, and customers experience better capabilities, not disruptive migration events. 

What You Bring 

Proven engineering leadership 

Substantial experience leading backend or platform teams delivering complex, high-throughput production systems, with direct accountability for delivery, quality, and team health. 

Service transformation depth 

Experience decomposing monoliths, extracting services, and defining domain boundaries, ownership models, and migration strategies within complex existing environments — and delivering those migrations to production. 

Credible backend and distributed-systems fluency 

Enough hands-on depth — in Java and Spring or comparable enterprise backend ecosystems — to review designs, ask the hard questions, spot risk in implementation plans, and unblock your teams. You don't need to write the code, but you need to earn the room. 

Migration safety instincts 

You understand compatibility strategies, staged rollout, data migration, dual-running, rollback, and the operational realities of moving live traffic and data between systems while preserving historical, reporting, and audit needs. 

Quality and operational discipline 

You treat automated testing, code review, observability, dependency health, secure coding, and production validation as essential parts of how software gets built — and you hold that bar for your teams. 

People development 

You hire well, coach deliberately, develop engineers into stronger versions of themselves, and manage performance honestly and with care. 

Cross-functional execution 

You create clarity across teams, communicate technical risk in business terms, sequence work against dependencies, and help stakeholders converge on decisions they can execute. 

An opportunity-focused approach to AI-assisted engineering 

You actively look for ways AI can expand your team's leverage across code comprehension, implementation, refactoring, test generation, and planning — and you help turn those into repeatable practices that make strong engineers more effective. 

Bonus Points 

Experience modernizing large Java and Spring estates, including runtime and framework upgrades. 

Experience with Oracle or other enterprise relational databases, Kafka or similar messaging systems, and complex data migration or reporting dependencies. 

Experience delivering shared or platform services consumed by multiple product teams, including versioning, deprecation, and consumer migration done well. 

Experience with cloud migrations (especially AWS) and decommissioning legacy infrastructure or data centers. 

Experience designing APIs and services for agentic or LLM consumption (MCP or similar frameworks). 

Experience leading teams through the adoption of AI coding assistants or agents in day-to-day engineering. 

What Success Looks Like 

The base service tier becomes real 

Shared services ship on a steady, predictable cadence. Each is adopted across every in-scope ABC application, and the duplicated product-specific builds behind them are retired — reducing cost, complexity, and maintenance burden with every domain delivered. 

Convergence advances without destabilizing the business 

Every cutover has clear boundaries, sequencing, ownership, safety controls, and hypercare. Customers never experience a migration event; they simply get a better, more consistent platform underneath the products they already use. 

The platform compounds 

New capabilities are built once and land everywhere. Products, AI agents, and partners all consume the same well-governed capability layer, and each converged domain makes the next one faster and safer to deliver. 

The team gets stronger 

Engineers grow in scope and skill, quality practices become consistent, AI leverage becomes normal working practice, and the team becomes a model for how ABC delivers complex platform change. 

Why This Matters 

Everything ABC is building — the unified member experience, embedded AI, the agent ecosystem, and the open platform — stands on the shared service tier this role delivers. The transformation succeeds only if these services are well-designed, safely landed, and genuinely adopted. 

This role connects platform strategy with team leadership and hands-on delivery. Done well, it turns a portfolio of parallel products into one platform: capabilities built once instead of three times, engineering effort shifted from duplication to innovation, and a foundation strong enough to carry everything ABC builds next.
