What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Staff Software engineer should be able to lead complex systems end-to-end, shape architectural direction, and grow the engineers around them. Someone who takes full ownership — from design to production to incident resolution — and drives impact across teams.

What will you do

Primary responsibilities include:

• Architect and own large-scale distributed systems end-to-end, from design through production.
• Drive technical direction and best practices across the team and adjacent teams.
• Lead delivery of complex, ambiguous initiatives with multiple stakeholders.
• Mentor junior and mid-level engineers through code reviews, pairing, and technical guidance.
• Own past incidents — lead root cause analysis, drive permanent fixes, and share learnings broadly.
• Communicate clearly with stakeholders — translate technical complexity into business context.
• Evaluate technology trade-offs and make pragmatic tech debt decisions that balance speed with long-term health.

What skills and experience should you bring

Ideal candidates will have:

• Education & Experience: Bachelor’s + 12 years of experience / Master’s + 8 years / PhD + 5 years.
• Core Engineering:Deep Java internals knowledge — concurrency, JVM, memory model, and performance
  tuning. Strong foundation in data structures, algorithms, and system design. Solid experience with unit and integration testing practices.
• Distributed Systems & Architecture: Proven experience designing distributed systems — partitioning, consistency, availability trade-offs. Hands-on with event-driven architecture and messaging platforms such as Kafka or SQS. Experience with high-scale API design, database design and sharding, and circuit breaker patterns.
• Cloud & Infrastructure: Hands-on with AWS core services: EC2, S3, SQS, IAM. Experience with Docker/containerisation and CI/CD pipelines.
• Leadership & Soft Skills: Strong ownership mindset — takes accountability for outcomes, not just tasks. Proven cross-team influence — drives alignment without formal authority. Track record of mentoring engineers and contributing to their career growth. Comfortable with ambiguity — breaks down unclear problems and delivers under uncertainty. Proactive career growth mindset — stays current with technology trends and industry
  standards.

Why SentinelOne?

AI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself. If you want to build where innovation and impact move together, this is that place.
