● Lead technical design discussions and help define software architecture, engineering standards, and reusable development patterns.
● Improve CI/CD pipelines, DevSecOps practices, test automation, monitoring, and platform automation.
● Troubleshoot complex production and non-production issues; analyze root causes and recommend long-term solutions.
● Partner with cross-functional teams to deliver secure, compliant, reliable, and maintainable software in a regulated enterprise environment.
● Mentor engineers through code reviews, technical guidance, and shared best practices.
Basic Requirements

● Experience building applications with Java, Python, React, JavaScript/TypeScript, REST APIs, or related full-stack technologies.
● Experience designing, developing, and optimizing database solutions using MongoDB, PostgreSQL, relational data models, document databases, query optimization, indexing, and data integration patterns.
● Hands-on experience with cloud-native architecture, preferably Azure, Kubernetes, containers, microservices, or serverless patterns.
● Hands-on experience with AI-assisted software development or agentic coding tools and practices, including Claude Code, GitHub Copilot, code analysis, automated test generation, documentation support, and developer productivity workflows.
● Experience designing or integrating APIs, distributed systems, event-driven services, or enterprise integrations.
● Experience with CI/CD pipelines, DevOps or DevSecOps practices, Git-based workflows, automated testing, and release processes.
● Experience applying secure coding, software quality, scalability, reliability, and maintainability practices.
● Experience working in Agile delivery environments with product, architecture, security, and operations partners.
● Bachelor’s degree in Computer Science, Engineering, Information Technology, or related field, or equivalent experience.
Preferred Skills/Experience
● Experience building AI applications using LLMs, RAG, vector databases, prompt engineering, orchestration frameworks, or agentic AI patterns.
● Experience with multi-agent systems, autonomous workflows, AI copilots, or AI-assisted automation.
● Experience with Azure services, Kubernetes operations, event streaming, messaging platforms, or API gateways.
● Experience with MongoDB, PostgreSQL, database performance tuning, schema design, indexing strategies, data migration, and secure data access patterns.
● Experience contributing to open-source frameworks, internal developer platforms, reusable libraries, or engineering accelerators.
● Experience with observability tools, infrastructure as code, policy-as-code, SRE practices, or platform engineering.
● Experience applying AI-assisted software development and agentic coding capabilities across the SDLC, including code generation, code review, repository analysis, test automation, documentation, risk detection, and developer productivity improvement.
● Experience working in healthcare, regulated technology, security-conscious, or compliance-driven environments.
Travel / Work Environment / Physical Requirements
