Software Engineer (backend)

Job Description

AB Testing Must have

We are seeking a Backend Engineer with proven experience at major tech companies building distributed systems serving millions of daily active users. The ideal candidate has worked in large engineering organizations (20+ BE engineers) with multiple teams contributing to a distributed backend architecture. They must demonstrate proficiency with modern development practices including A/B testing, feature flagging, distributed systems design, and data-driven decision making. This role requires someone who can work autonomously in a fast-paced environment, collaborate effectively with product managers, SREs, data scientists, and other backend teams, and think strategically about system architecture and scalability rather than just completing assigned tasks. Experience with high-scale consumer applications (10M+ DAU) is strongly preferred. Please avoid candidates who have only worked on small-scale applications or lack experience with rigorous engineering processes typical of leading tech companies at scale, regardless of years of experience claimed.

Technical excellence is essential for this role, as you'll be working on our microservices architecture that handles massive scale and traffic spikes. The ideal candidate demonstrates strong proficiency in distributed systems concepts including consistency models, fault tolerance, and horizontal scaling. You must be comfortable designing and implementing high-throughput, low-latency services that maintain performance during peak loads. Additionally, you should have excellent communication skills with the ability to clearly articulate technical decisions, create comprehensive documentation, and collaborate effectively with cross-functional teams in a remote environment. You'll be expected to participate in architecture reviews, contribute to technical discussions, and deliver high quality code.

The Post Detail Page (PDP) Experience team is responsible for one of the highest traffic pages on the platform: the Comments page. We know that conversations are our lifeblood so we strive to ensure viewing content and the surrounding conversation is appealing, intuitive and delightful. This is a high impact role where you will drive related technical & product strategy, operations, architecture, and execution for one of the largest sites in the world.

What You'll Do:

Work cross-functionally, collaborate and partner with product, design, and other engineering counterparts to execute on product and business strategy and build novel products and features that our users will love.

Contribute to the full development cycle: technical design, development, test, experimentation, analysis, and launch. You'll be reviewing code and design docs, giving feedback on product specs and mocks.

Participate with a team of thoughtful, fast-moving, and motivated engineers. Contribute to standards that improve developer workflows, recommend best practices, and help mentor engineers on the team to grow their technical expertise.

Continuously learn and improve your technical and non-technical abilities.

You will work with the existing engineering team and help contribute to the direction of the project and team

Create and maintain APIs, rSpec testing suite, and middleware to facilitate data flow between systems

Perform system analysis, troubleshooting, and debugging to identify and resolve integration issues

Ensure compliance with security protocols and data privacy regulations during integration processes

Troubleshoot and optimize application performance to provide optimal experience

Ability to design maintainable database schemas and easy-to-understand data structures

Ability to design technical solutions with little direction or guidance

Engage in the team's organizational processes, such as planning, backlog refinement, and sprint reviews, to ensure effective collaboration and feedback

Proactively identify and address potential technical issues and bottlenecks

Qualifications for this role:

Minimum 8+ years of post-internship, full-time, hands-on, professional software development experience developing distributed backend systems at scale.

Expertise in Java, Python, Go, or Rust

Experience with distributed systems, microservices architecture, and handling high-throughput workloads

Familiarity with software engineering best practices such as unit/integration/end-to-end testing, design documents, CI/CD, A/B testing, code reviews, and documentation

Strong organizational skills, the ability to prioritize tasks and keep projects on schedule.

Excellent communication skills. You collaborate effectively with teams in a fully remote environment and discuss complex topics with technical and non-technical audiences.

BS degree in Computer Science, a similar technical field of study or equivalent practical, professional, hands-on experience.

You love to build new things and thrive in ambiguity and even failure. You care about innovation.

Experience with message queues (Kafka, RabbitMQ), caching systems (Redis, Memcached), and database technologies (SQL and NoSQL)

Experience with GraphQL, REST, HTTP, and the ability to design maintainable APIs
