Staff Engineer

HackerRank helps companies like NVIDIA, Amazon, and Microsoft hire and upskill the next generation of developers based on skills, not pedigree. Our platform is trusted by over 2,500 of the world's most innovative companies to build strong engineering teams ready for what's next.

Software has entered an era where humans and AI build side by side. As this shift accelerates, the definition of strong technical talent is changing. We give companies better ways to identify and invest in next-generation skills.

People at HackerRank care deeply about the impact of their work and sweat the small details so our customers can be wildly successful with products they genuinely love to use. We move with urgency and believe great outcomes come from high standards.

About the role

This is a senior IC role for a backend specialist who can alternate between two operating modes: (1) shaping platforms that many product teams build on, and (2) diving deep with a team to crack a hard, high-stakes technical problem. You will also build AI-native capabilities into our platform (LLM orchestration, evaluation, cost and latency controls, guardrails), build novel systems, and raise the reliability, performance, and developer experience across services.

You will partner across multiple product groups, write crisp technical strategy, and be the engineer others look to for judgment, taste, and depth.

What you will do

Align engineering roadmap with business outcomes. Translate company goals and customer needs into a technical roadmap. Communicate trade-offs and decisions in plain language

Design and evolve core platforms for APIs, data, and AI that are scalable, observable, secure, and cost-aware ( thousands of concurrent assistant sessions, bursty traffic).

Embed AI as a first-class concern: request orchestration, evaluation harnesses, guardrails and safety, prompt and data governance.

Partner to deliver impact: Work with product managers and, when needed, customer-facing teams to drive impact.

Mentor: raise the bar through reviews, design reviews, and hands-on pairing; be a model others emulate.

Who you are

Backend/platform engineer with over 8 years of experience building and operating production-grade services with clear ownership of outcomes.

Strong in system design and distributed systems, with hands-on experience across cloud platforms (AWS/GCP), containers & Kubernetes, Infrastructure as Code (Terraform), and CI/CD automation.

Depth in one or more of Go, Java, Ruby, Python, or JavaScript, and ability to quickly learn new languages and frameworks.

Proficient with Postgres/MySQL and NoSQL databases, and experienced in event-driven architectures using Kafka or similar for streaming and async

Excellent communicator who writes clear documentation, explains trade-offs simply, mentors peers, and influences across teams without direct authority.

Even better if you have

Exposure to AI systems in production such as LLM gateways, prompt or model evaluation and guardrails.

Experience improving developer experience across the company.

Public artifacts such as design write-ups, talks, or OSS contributions.

You will thrive in this role if

You communicate with clarity and empathy, engaging both technical and non-technical stakeholders to build shared understanding and drive complex decisions forward.

Balance long-term decisions with fast, incremental delivery.

Care about developer experience as much as raw performance and reliability.
