• Establish, document, and enforce engineering standards, coding guidelines, and best practices across multiple engineering teams.
• Define and manage CI/CD pipelines and release management processes, including quality and security gates, rollback strategies, and progressive delivery mechanisms.
• Champion safe releases by designing checks and balances that gate production, ensuring changes are tested, observable, and reversible.
• Lead SRE practices such as on-call operations, incident response, and post-incident reviews to minimize customer impact and improve system resilience.
• Design and maintain instrumentation and guardrails so that production failures degrade gracefully and fail safe rather than fail loud.
• Collaborate with engineering teams to modernize legacy systems, including evolving a monolith into microservices and microfrontends using domain-driven design and strangler patterns.
• Plan and execute monolith-to-microservice extractions, including dual-write validation, traffic splitting, canary and per-tenant rollouts, and shared database decomposition.
• Contribute to both backend services and frontend applications, owning performance, monitoring, and reliability across the stack.
• Review architecture and code across multiple teams, identifying technical risks early and guiding engineers toward robust, maintainable solutions.
• Integrate with third-party APIs at scale, designing resilient patterns for REST, SOAP, webhooks, idempotency, retries, and backoff strategies.
• Design and operate data models using both relational and NoSQL databases, ensuring appropriate schema design and access patterns.
• Write clear, actionable design documents, ADRs, and runbooks that enable other engineers to implement solutions without extensive meetings.
• Promote reusable abstractions and platform capabilities while avoiding unnecessary complexity and over-engineering.
• Operate security tooling such as dependency and vulnerability scanners, SAST/DAST, and container image scanning in production environments.
• Run observability and on-call tooling in production, ensuring alerts are meaningful, actionable, and aligned with SLOs.
• Support and guide modernization of a legacy monolith while helping redesign components into microfrontends and next-generation services.
• Collaborate closely with senior engineering leadership, providing visibility into platform health, risks, and modernization progress.
• Act as a platform leader who notices systemic problems early, proposes pragmatic solutions, and drives cross-team initiatives to completion.
• Promote a culture of ownership, continuous improvement, and learning across the engineering organization.

• 7+ years of professional software engineering experience, including at least 2 years operating as a tech lead or staff engineer.
• Hands-on experience building and operating production systems, with at least 2+ years at a senior or Staff level.
• Proficiency in at least three of the following: Python, Java/Spring Boot, PHP/Laravel, TypeScript/React, with the ability to ship production code in a primary stack and review pull requests in the others.
• Hands-on production experience with AWS services including Lambda, EventBridge, DynamoDB, ECS or Fargate, RDS/Aurora, API Gateway, S3, SQS/SNS, CloudWatch, and Secrets Manager.
• Practical experience with AWS serverless architectures (Lambda, EventBridge, DynamoDB, Step Functions) and traditional service architectures (ECS, RDS, API Gateway).
• Proven experience breaking a monolith into microservices, including defining domain-driven service boundaries, applying strangler fig and anti-corruption layer patterns, and leading at least one non-trivial extraction in production with dual-write validation, traffic splitting, and canary or per-tenant rollout.
• Full-stack delivery experience, including shipping frontend (React or similar) and backend services in the same product area and owning performance and monitoring for both.
• Experience integrating with third-party APIs at scale, including REST, SOAP, webhook patterns, idempotency, retry and backoff strategies, and handling vendor-specific quirks.
• Comfort with both relational databases (MySQL/Aurora) and NoSQL databases (DynamoDB), including designing and operating appropriate data models.
• Security-minded engineering practices, including dependency and vulnerability management, timely patching and upgrades, and secure-by-default design.
• Experience with SRE practices, including observability, SLOs and error budgets, on-call operations, and incident response.
• Hands-on experience with CI/CD and release management, including quality and security gates, rollback strategies, and progressive delivery.
• Ability to work comfortably in at least two of Python, Java/Spring Boot, and TypeScript/React, and to read and safely modify legacy PHP code.
• Strong written communication skills, with the ability to produce clear design documents and standards that peers can implement without additional meetings.
