About this role.
Quora is hiring a new-graduate Software Engineer to help build and operate its machine-learning platform and ranking infrastructure. The role focuses on distributed systems, reliable model serving, GPU performance optimization, ML developer tooling, and feature-store modernization. Engineers will work with Python, Go, C++, PyTorch, Kubernetes/EKS, NVIDIA Triton, Ray, and AWS while shipping production work early with mentorship from senior engineers. The position includes participation in an on-call rotation and requires overlap with Pacific-time coordination hours. It is well suited to recent or upcoming technical graduates interested in infrastructure and large-scale machine learning systems.

Sample interview questions
I would first confirm the scope using latency percentiles, error rates, traffic volume, and resource metrics. I would then isolate whether the bottleneck is in request queuing, model inference, networking, CPU/GPU utilization, memory pressure, or a recent deployment, using traces and profiling data. After identifying the likely cause, I would mitigate impact through rollback, autoscaling, traffic controls, or configuration changes, then validate the fix with monitoring and a documented post-incident review.
I would balance latency, throughput, cost, model quality, and reliability. Techniques such as batching, model compilation, precision reduction, concurrency tuning, and instance selection can improve throughput, but may increase tail latency or affect numerical behavior. I would benchmark representative workloads, define service-level objectives, and make changes incrementally with production observability.
I would separate model packaging, validation, deployment, serving, and monitoring into clear stages. The platform should support versioned artifacts, automated compatibility checks, canary releases, rollback, health checks, capacity controls, and metrics for model and infrastructure behavior. I would also prioritize a simple developer workflow so ML engineers can deploy safely without needing to manage all underlying infrastructure details.
I would begin with the core concepts and build a small hands-on project that exercises the most relevant workflow. Next, I would read existing internal configurations and documentation, ask targeted questions of experienced teammates, and use tests or a sandbox environment to validate my understanding. I would document what I learn and gradually take on well-scoped production tasks with appropriate review.
An effective on-call engineer stays calm, communicates status clearly, follows established runbooks, and focuses first on reducing user impact. For a new engineer, I would prepare by understanding alerts, dashboards, escalation paths, and common failure modes, while pairing with experienced teammates when needed. After an incident, I would help improve monitoring, documentation, or automation so the same issue is easier to handle in the future.

About Quora:
Quora’s mission is to grow the world’s collective intelligence. To do so, we have two platforms:
Quora: a global knowledge sharing platform with over 300M monthly unique visitors, bringing people together to share insights on various topics and providing a unique platform to learn and connect with others.
Poe: a platform providing millions of global users with one place to chat, explore and build with a wide variety of AI language models (bots), including GPT-5.6-Sol, Claude-Opus-5, Claude-Fable-5, Claude-Sonnet-5, Kimi-K3, and thousands of others. As AI capabilities rapidly advance, Poe provides a single platform to instantly integrate and utilize these new models.
Behind these products are passionate, collaborative, and high-performing global teams. We have a culture rooted in transparency, idea-sharing, and experimentation that allows us to celebrate success and grow together through meaningful work. Join us on this journey to create a positive impact and make a significant change in the world.
This role will be working on our Quora product.
About the Team and Role:
Machine Learning is central to Quora’s mission of growing the world’s collective intelligence. We have 100+ Machine Learning models in production powering various product features. We use a variety of algorithms — everything from linear models to decision trees and deep neural networks. Our production models operate at a huge scale, serving hundreds of millions of people using Quora every month.
Our team owns Quora’s ML platform and ranking infrastructure across four areas: serving reliability, ML engineer enablement and developer velocity, business impact, and cost efficiency. We want to empower all ML engineers at Quora to be as impactful as they can be in solving different ML problems at scale.
As a Software Engineer (New Grad) on this team, you’ll work at the intersection of Machine Learning, Distributed Systems, and GPU Serving performance — and your work will have an enormous impact on Quora’s long-term success.
No previous ML infrastructure experience is required for this role. You’ll be joining a team of senior and staff engineers, learning this stack from the people who built it, with a dedicated mentor and strong technical guidance — and you’ll be shipping to production in your first few weeks.
Stack: Python, Go, C++, PyTorch, Kubernetes/EKS, NVIDIA Triton, Ray, AWS
