About the role

Why N-able

At N-able, we’re not just helping businesses be secure —we’re redefining what it means to be cyber resilient. Our end-to-end platform blends AI-powered capabilities and flexible tech stacks, so customers can manage, secure, and recover with confidence. But the real power behind it all?

Our people. We’re a global crew of N-ablites, who love solving complex problems, sharing knowledge, and delivering solutions that actually make a difference. If you're into meaningful work, fast growth, and a team that’s got your back, you’ll be surrounded by people who believe in what they do—and in you.

What You'll Do

  • Implement backend features in Java to your team's definition of done
  • Write unit and integration tests alongside the code they cover
  • Debug against runtime behaviour in a distributed system — logs, APIs, queues, databases
  • Participate actively in code review, both giving and receiving
  • Follow branching, cherry-pick and release-backport conventions
  • Raise design questions with your Staff Software Engineer early, before the work is built

What You'll Bring

  • 1+ years building backend services in Java
  • Understanding of REST APIs and relational databases
  • Ability to debug across service boundaries rather than only within one component
  • Familiarity with Git branching workflows and CI pipelines
  • Demonstrated use of Spec-Driven Development (SDD) and AI-assisted development lifecycle (AI-DLC) practices, or a directly equivalent methodology
  • Exposure to event-driven systems or message queues is beneficial
  • TypeScript experience is beneficial

Purple Perks

  • Group Medical , Personal Accident & Term life coverage
  • Generous PTO and observed holidays
  • 2 Paid VoluNteer Days per year
  • Employee Stock Purchase Program
  • FuN-raising opportunities as part of our giving program
  • N-ablite Learning – custom learning experience as part of our investment in you
  • The Way We Work – our hybrid working model based on trust and flexibility

Round 4: HR & Cultural Fit Discussion N-able Core Values, Learning Agility & Offer Terms Demonstrate passion, strong communication, and readiness for full-time collaboration.
Technical questions 5
Explain OOP (Object-Oriented Programming) principles with real-world examples in Java. Answer
Model answer: 1. Encapsulation (data hiding via private fields/getters). 2. Abstraction (hiding implementation complexity). 3. Inheritance (code reusability). 4. Polymorphism (method overriding/overloading).
What is the time and space complexity of QuickSort vs MergeSort? Answer
Model answer: QuickSort: Average O(N log N) time, O(log N) space. Worst O(N^2). MergeSort: Guaranteed O(N log N) time, but requires O(N) auxiliary space.
Explain the difference between SQL Indexing (B-Tree vs Hash) and when not to use an index. Answer
Model answer: Indexes speed up SELECT queries via B-Trees. However, they slow down INSERT, UPDATE, and DELETE operations because indexes must be updated on disk. Avoid on low-cardinality columns (e.g., boolean flags).
What happens under the hood when you enter a URL in a browser? Answer
Model answer: 1. DNS lookup (resolves IP). 2. TCP 3-way handshake (SYN, SYN-ACK, ACK). 3. TLS negotiation for HTTPS. 4. HTTP GET request sent. 5. Server responds with HTML/CSS/JS. 6. Browser renders DOM & CSSOM tree.
What is the difference between REST and GraphQL APIs? Answer
Model answer: REST uses multiple fixed endpoints with possible over/under-fetching. GraphQL uses a single endpoint allowing clients to query exact fields in a single request.
Behavioural & HR questions 3
Why do you want to join N-able as a Software Engineer (Java)?

Use the STAR method: Situation (project context), Task (what needed solving), Action (specific tools/logic applied), Result (quantifiable positive outcome).
How do you handle strict deadlines or sudden scope changes?
Explain your prioritization strategy, proactive communication with mentors/peers, and agile mindset.
