About the Team

About the Role

We are seeking a Senior Software Development Engineer with a passion for architectural design and high-performance this role you will own the technical design and optimization of our core software platforms. You are a hands-on technical leader who can independently architect scalable systems while simultaneously deep-diving into code-level profiling to eliminate latencies and resource bottlenecks. You will bridge the gap between application code and cloud infrastructure ensuring our software is built from the ground up to be fast lean and resilient under production loads.

What you will do

• Design and Architect High-Performance Services: Lead the technical design of core features and microservices ensuring they are decoupled horizontally scalable and optimized for low-latency and high-throughput.

• Write Core Highly Efficient Code: Act as a primary individual contributor writing clean production-ready code for critical paths and refactoring legacy components for maximum efficiency.

• Diagnose and Resolve Performance Bottlenecks: Conduct deep-dive profiling memory footprint analysis and CPU utilization reviews using APM tools to proactively find and fix bottlenecks before they impact production.

• Optimize the Data Layer: Own the efficiency of data flow including designing caching strategies optimizing database schemas/queries and selecting efficient serialization formats.

• Partner with Infrastructure Teams: Collaborate closely with the Cloud Infrastructure team to ensure the software design perfectly aligns with our AWS architecture maximizing compute memory and network efficiency.

• Raise the Technical Bar: Drive rigorous code reviews focusing heavily on architectural alignment concurrency hazards and algorithmic efficiency. Mentoring other engineers on writing performance-first code.

• Establish Benchmarking and Load Testing: Implement automated micro-benchmarking and load-testing workflows within the CI/CD pipeline to catch performance regressions early.
