Profile: Lead Engineer that owns the technical architecture - full stack, strong data and app performance experience, Agentic AI solid communication skills

 

End-to-End Solution Ownership & Product Engineering (40%):

  • Own delivery of complex, end-to-end engineering solutions—from data generation and ingestion through analytics, APIs, and user-facing experiences
  • Develop a deep understanding of business workflows, especially high-scale exam and operational systems
  • Partner with product, architecture, and engineering teams to shape requirements, define scope, and provide accurate level-of-effort estimates
  • Drive sprint planning, technical design discussions, and code/design reviews with a focus on speed, quality, and scalability 

Architecture, Data Engineering & Implementation (40%):

  • Lead design and implementation of scalable, high-performance, cloud-native data and application platforms
  • Architect data generation systems (synthetic, event-based, telemetry-driven) to support testing, analytics, and AI model development
  • Engineer high-performance systems, focusing on latency, throughput, resiliency, and cost efficiency
  • Implement robust observability, telemetry, and performance monitoring across all layers
  • Establish and enforce standards for automation, reliability, and performance engineering
  • Integrate AI-driven components (prediction, anomaly detection, intelligent insights) into production systems

 Agentic AI & AI-Driven Development (20%):

  • Design and build agentic AI systems that can autonomously reason, plan, and execute tasks across engineering workflows
  • Leverage LLMs and orchestration frameworks to enable intelligent automation in data pipelines, testing, and operations
  • Incorporate AI-assisted development practices, including code generation, code review augmentation, and developer productivity tooling
  • Evaluate and implement AI-native architectures, including tool-using agents, multi-agent systems
  • Ensure responsible, secure, and scalable deployment of AI capabilities in production environments 

Technical Leadership & Engineering Excellence:

  • Act as a senior technical leader driving architectural decisions and solving complex system challenges
  • Mentor engineers across backend, data, performance, and AI domains
  • Champion engineering best practices in performance optimization, scalability, security, and reliability
  • Clearly communicate technical strategy, tradeoffs, and decisions to stakeholders 

Performance Engineering & Operational Readiness:

  • Lead performance engineering efforts, including load testing, capacity planning, and system tuning
  • Build frameworks for data-driven performance benchmarking and optimization
  • Ensure systems meet strict SLAs for availability, latency, and scalability
  • Proactively identify risks and ensure readiness for high-stakes operational events

You have:

  • 7+ years of experience building and operating scalable, distributed, cloud-native systems, including data platforms and APIs
  • Strong experience with end-to-end system design, from data generation to front-end delivery
  • Proven expertise in performance engineering, including profiling, load testing, and system optimization
  • Hands-on experience with backend technologies such as Node.js (TypeScript preferred) and Python, building APIs and event-driven systems
  • Strong experience designing and operating data pipelines and data platforms (real-time and batch)
  • Experience building modern front-end applications (React/TypeScript) for data-intensive interfaces
  • Deep knowledge of AWS services (Lambda, S3, Step Functions, SNS/SQS, Redshift, Athena, DynamoDB, etc.)
  • Experience with Infrastructure as Code (CDK, Terraform, CloudFormation)
  • Strong understanding of event-driven architectures, streaming, and telemetry systems
  • Experience implementing observability and monitoring solutions (e.g., Grafana or similar)
  • Experience with AI/ML systems in production, including model integration and operationalization
  • AI & Modern Engineering Capabilities
  • Experience working with LLMs, agent frameworks, or AI orchestration tools
  • Familiarity with agentic workflows, autonomous system
  • Hands-on experience with AI-assisted coding tools (e.g., GitHub Copilot, ChatGPT, or similar) and integrating them into development workflows
  • Understanding of RAG architectures, prompt engineering, and tool-augmented AI systems

Nice to Have:

  • Experience in high-scale, mission-critical environments with strict reliability requirements
  • Familiarity with cell-based or multi-tenant architectures
  • Experience designing systems for data isolation, security, and performance segmentation
  • Exposure to synthetic data generation or simulation systems
  • Experience with multi-agent AI systems or advanced automation pipelines
  • Experience with MCP servers and agents skills
