Full Job Description
About the Role

We are seeking a Senior Software Development Engineer with a passion for architectural design and high-performance engineering. In 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.


About You

Basic Qualifications (Required)
  • Education: Bachelor's or Master's degree in Computer Science, Engineering, or equivalent practical work experience.
  • Core Development: 8+ years of professional software development experience writing clean, high-concurrency, and production-grade code utilizing Python, GoLang, or Java/C++.
  • System Architecture: 4+ years of experience designing, building, and evolving scalable, distributed microservices architectures.
  • Performance Engineering: Proven track record of diagnosing and resolving complex performance issues, including memory leaks, CPU bottlenecks, and database/IO serialization delays.


Other Qualifications (Preferred)
  • Profiling & APM Tools: Hands-on experience with profiling, tracing, and APM tools (e.g., Datadog, New Relic, OpenTelemetry, pprof, or CloudWatch) to analyze runtime application behavior.
  • Data Layer Optimization: Strong expertise in database optimization, including writing efficient SQL/NoSQL queries, indexing strategies, and designing multi-tier caching layers (e.g., Redis, Memcached).
  • Cloud & Infrastructure Awareness: Solid understanding of how application code interacts with cloud infrastructure (specifically AWS or GCP compute, memory, and networking boundaries).
  • Testing & Benchmarking: Experience establishing micro-benchmarking, load testing, and stress testing practices (e.g., using Locust, JMeter, or k6) within CI/CD pipelines.
  • Concurrency & Parallelism: Deep understanding of asynchronous programming, multi-threading, memory management, and distributed systems concepts.
  • Technical Leadership: Demonstrated ability to drive design reviews, raise the bar for code quality through rigorous peer reviews, and mentor mid-level engineers on writing performance-first code.
  • Collaboration: Strong analytical and problem-solving skills, with a proven ability to collaborate effectively with platform, data, and product engineering teams.

Our Approach to Flexible Work

With Flex Work, we're combining the best of both worlds: in-person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.
