At HackerRank, our mission is to change the world to value skills over pedigree. Thousands of companies use our AI-powered platform to hire next-gen developers based on what they can do, not just what’s on their resume. We’ve powered 300M+ code runs and built a global community of 26M+ developers.

We’ve entered a new era of software development where humans and AI build together. This changes everything- from how developers grow to how companies hire and upskill tech talent. We’re embracing this shift head-on and reinventing our products to meet the moment.

We’re a high-performing, mission-driven team that truly, madly, deeply cares about what we do. We don’t see velocity and quality as tradeoffs; both matter. If you take pride in high-impact work and thrive in a driven team, HackerRank is where you belong.

We are revolutionizing technical hiring by giving companies a skills-based hiring platform that enables our customers to assess technical skills effectively. We are growing fast and looking to add to our Engineering team. This is a full-time, hybrid position based in Santa Clara, CA.

As a Software Engineer, working with the ML Team, you are ready to make an impact on the lives of millions of developers as you build the platform for them to showcase their skills and get hired. We’re responsible for building the world’s leading technical interview platform. We believe in “Extreme ownership,” and you’ll have immense ownership both in terms of product and engineering.

What you will do:

• End-to-End Project Delivery: Develop and deploy large, complex projects across both frontend and backend stacks. Work closely with cross-functional teams to ensure smooth project execution.
• Technical Expertise: Participate in technical discussions, provide guidance on full-stack solutions, and troubleshoot challenges across the application.
• Quality & Performance Enhancement: Monitor and improve key business and engineering metrics related to performance, quality, and system availability across the entire application.
• Collaborative Development: Engage in code reviews and design discussions, ensuring best practices are followed for both backend and frontend codebases.
• Process Improvement: Identify and implement opportunities to automate and streamline processes while aligning security with business goals.

What you bring:

• Technical Proficiency:
  • Extensive experience building web-based products with full-stack expertise.
  • Proficiency in at least one dynamic programming language and an MVC framework (e.g., Python, Ruby on Rails, NodeJS, Golang for backend; React.js for frontend).
• Database and Cloud Experience:
  • Skills in database modeling, optimization, and query tuning (preferably with relational databases).
  • Experience with cloud platforms (AWS, GCP) and CI/CD tools, ensuring robust and scalable deployments.
• Systems Design:
  • Demonstrated ability to architect and develop highly available, scalable, and secure distributed systems.
  • Adaptability and Innovation:
  • A proactive approach to adopting new technologies and continuously improving code quality through incremental changes.
• Effective Communication:
  • Strong written and verbal communication skills, with the ability to clearly explain technical concepts to both technical and non-technical team members.

Bonus Skills:

• Extensive experience as a Python Developer
• Experience with containerisation and orchestration tools such as Kubernetes and Docker.
• Experience in Data Pipeline Engineering, including designing, building, and optimizing data workflows.
• Familiarity with working on projects involving Large Language Models (LLMs) and related technologies.

We work across a modern, scalable tech stack: React, TypeScript, Node.js, Ruby on Rails, Go, Kafka, Kubernetes, AWS, and Postgres. Our engineering team builds products that directly impact how developers get discovered, evaluated, and hired globally. We're currently building next-gen developer workflows using AI; think intelligent auto-scoring, AI-powered question generation, and adaptive skill insights. We’re also reimagining core experiences across assessments, interviews, and candidate engagement to make hiring faster, fairer, and more human.
