Solutions Architect – API & Data Platforms

Key Responsibilities:

API Architecture & Design

• Architect and govern enterprise-grade RESTful, GraphQL, and gRPC APIs across microservices and distributed systems
• Define API design standards, versioning strategies, lifecycle management, and deprecation policies
• Design and implement API Gateway solutions (Kong, AWS API Gateway, Apigee, Azure APIM)
• Establish API security frameworks- OAuth 2.0, OpenID Connect, JWT, mTLS, rate limiting, and throttling Drive API-first development culture across engineering teams
• Design event-driven and async API patterns using message brokers (Kafka, RabbitMQ, Azure Service Bus)

Database Architecture:

• Architect polyglot persistence strategies - selecting the right database for the right workload (relational, NoSQL, NewSQL, time-series, graph, vector)
• Design highly available, fault-tolerant database architectures with replication, sharding, partitioning, and failover strategies
• Lead data modeling efforts across OLTP, OLAP, and hybrid workloads
• Define strategies for database migrations, schema evolution, and zero-downtime deployments
• Oversee multi-region and multi-cloud database deployments
• Govern database security: encryption at rest/in transit, RBAC, auditing, and compliance

Performance Optimization:

• Identify and remediate performance bottlenecks across API layers, databases, networks, and application tiers
• Define and enforce SLAs, SLOs, and SLIs for latency, throughput, availability, and error rates
• Architect caching strategies -in-process, distributed (Redis, Memcached), CDN, and query-result caching
• Conduct load testing, stress testing, and capacity planning using tools like k6, Gatling, JMeter
• Implement query optimization, indexing strategies, execution plan analysis, and connection pool tuning
• Design async processing and queue-based load leveling to absorb traffic spikes
• Lead root cause analysis (RCA) on production performance incidents
