Summary

Role : Lead Engineer

Location :Bethesda , MD

Hybrid 2-3 days

Client :Hospitality Client

The Lead Engineer will lead the replat forming of a mission-critical API platform from a legacy framework to Java Spring Boot WebFlux using AI-assisted development. The platform serves customer-facing web and mobile experiences and high-impact internal applications, so reliability, security and backward compatibility are non-negotiable.The role also helps establish AI-assisted development as a repeatable practice. You will lead a team delivering with Cursor (or an equivalent AI coding tool) under a structured AI development lifecycle (AI-DLC or equivalent), and turn what works into patterns, guardrails and metrics other teams can adopt.

Technical leadership and migration

Own the technical design and delivery of the replatforming effort: REST and SOAP APIs migrated from a legacy framework to Spring Boot WebFlux with contract and behavioral parity.
Define the target reference architecture: reactive patterns, error handling, resiliency (timeouts, retries, circuit breakers), observability and security for identity and PII data.
Plan and run a low-risk cutover strategy (strangler pattern, parallel run, traffic shadowing, feature flags, staged rollout) with no disruption to consuming applications.
Partner with integration owners across the architecture to manage API contracts, dependencies and deprecation.
Operationalize AI-DLC or an equivalent AI development lifecycle across the team: AI-supported inception (requirements, legacy code analysis, API inventory), construction (code generation, test generation, refactoring) and operations (deployment, monitoring, runbooks), with human approval at each gate.
Build and maintain the team's Cursor setup: project rules, prompt and context libraries, reusable templates, and agent workflows for repeatable legacy-to-target conversion patterns.
Use AI to accelerate legacy comprehension: documenting existing application behavior, generating characterization tests and contract tests before code is migrated.
Coach engineers on effective AI pairing: when to trust, verify, or reject AI output.
Implement AI guardrails: approved tools and models, data handling rules (no customer data or secrets in prompts), secure coding standards, and mandatory human review of AI-generated code.
Enforce quality gates in CI/CD: static analysis, SAST/DAST, dependency and license scanning, test coverage thresholds, and performance baselines.
Maintain traceability of AI-assisted changes for audit and compliance needs.
Define and report pilot metrics: cycle time, throughput, defect escape rate, rework, test coverage, cost per API migrated, and developer experience.
Produce the playbook, reference implementations and lessons learned that other teams will use to adopt AI-assisted development.
Present progress and findings to engineering leadership and architecture governance forums.

Required qualifications

12+ years of software engineering experience, including 3+ years leading engineering teams or technical workstreams.
Expert-level Java: concurrency, performance tuning, and modern language features.
Deep hands-on Spring Boot experience, including Spring WebFlux and Project Reactor (Mono/Flux, backpressure, non-blocking I/O, reactive testing with StepVerifier).
Proven experience building and operating high-volume REST APIs; working knowledge of SOAP/WSDL services and how to preserve or modernize them.
Hands-on use of Cursor or an equivalent AI coding tool (GitHub Copilot, Claude Code, Windsurf, Amazon Q Developer) in production delivery, including configuring rules, context and prompts for a team.
AWS or equivalent cloud (Azure, Google Cloud Platform): containers (EKS/ECS or Kubernetes), API gateways, IAM, secrets management, managed databases and caching, and infrastructure as code (Terraform or CloudFormation).
CI/CD and automated testing: unit, integration, contract (e.g. Pact, Spring Cloud Contract) and performance testing.
Security fundamentals for identity and customer data: OAuth 2.0/OIDC, encryption, PII handling, OWASP API Top 10.
Observability: structured logging, metrics and distributed tracing (e.g. OpenTelemetry, Datadog, CloudWatch, Splunk).
Knowledge of event streaming with Apache Kafka (producers/consumers, topic design, schema management) and large-scale distributed databases such as Apache Cassandra (data modeling, consistency tuning, reactive drivers).
Sets technical direction and makes architectural trade-offs under delivery pressure, documenting decisions (ADRs) so others can follow them.
Breaks a large migration into sequenced, estimable increments and keeps delivery predictable.
Mentors engineers of mixed experience levels in reactive Java and AI-assisted engineering.
Leads rigorous code and design reviews, holding AI-generated code to the same standard as human-written code.
Manages risk proactively: identifies dependencies, failure modes and rollback plans before they become incidents.
Works effectively with onshore/offshore and vendor or partner teams.
Communicates clearly to both engineers and executives; can explain AI-assisted delivery outcomes in terms of speed, cost, quality and risk.
Builds adoption of new ways of working, addressing skepticism with evidence.
Manages stakeholders across product, architecture, security, QA and operations teams.
Reports progress transparently, including what is not working, not just successes.
Keeps skills current as AI tooling and practices evolve.
Takes ownership of production incidents affecting customer-facing systems, from response through resolution and follow-up.

Preferred qualifications

Experience with Play Framework and Akka (Scala or Java), especially reading and migrating legacy Play controllers, actors and routing.
Has led or played a key role in an AI-assisted replatforming or modernization effort, with measurable results on speed or quality.
Experience applying a structured AI development methodology such as AI-DLC or equivalent, or building team-level AI coding standards and governance.
Background in customer identity, CIAM, profile or customer data platforms in regulated or high-availability environments.
Familiarity with privacy and compliance requirements (e.g. SOC 2, PCI DSS, GDPR, CCPA).
Experience with MCP servers, AI agents or custom tooling that connects AI coding assistants to internal systems and documentation.
Relevant certifications such as AWS Certified Solutions Architect or Developer, or Spring Professional.
Experience with behavior-driven development (BDD) and frameworks such as Cucumber, including setting the team's approach to executable specifications that verify behavioral parity during migration
