Senior Forward Deploy Engineer (Fullstack - Java/React)

As a Senior Forward Deploy Engineer at SentinelOne, you will sit at the intersection of our customers and our product. Your time splits between customer engineering teams and our own codebases– shipping the integrations, fixes, and platform improvements customer deployments require. Your work will touch many products and services across the company, including our data pipeline and the Singularity Data Lake and EventDB (our highly scalable columnar database that ingests Petabytes of data per day). You'll work closely with customers to understand their environments, translate ambiguous requirements into shipped solutions, and build integrations, customizations, and upstream product contributions that unlock real business value.

What Will You Do?

• Software Development (fullstack; primarily React/Java): Dive deep into coding, turning customer requirements and product gaps into shipped solutions. Write robust tests, tackle bugs with finesse, and ensure top-notch security in your code. Expect to move between codebases regularly, including on escalated issues that span multiple products.
• Customer Engagement and Requirements Gathering: Partner with customers and our field teams to understand customer environments, goals, and constraints. Turn loose, ambiguous (possibly contradictory!) asks into a clear technical strategy. Carry field learnings back into product and engineering planning while advocating for what customers need. Occasionally support pre-sales scoping where early engineering input shapes a good outcome.
• Customer Integrations, Deployments, and Enablement: Own the design and delivery of integrations that connect SentinelOne products into customer environments. Often this is work you will do alongside the customer's engineers, shaping both the solution and the knowledge transfer that goes with it. Produce the runbooks, integration docs, and executive-level technical communication that let customers operate independently.
• Upstream Contributions to the Core Product: When something needs fixing or improving in the core platform to make a customer whole, you go do it. Partner with platform teams to get contributions reviewed and supported long-term, and know when to invest in the long-term fix versus the near-term unblock. Along the way, build the tooling that codifies repeatable patterns and scales the whole Forward Deploy function.
• Build and Review Technical Specifications: Architect end-to-end solutions for complex problems with loose definition, sometimes spanning multiple codebases and owning teams. Document trade-offs and critical implementation details; review and provide meaningful feedback on other specs, understanding broader patterns and downstream/upstream dependencies.
• Code Review: Champion code quality, security, and efficiency. Your keen eye for detail will guide you in reviewing and elevating our codebase– including the codebases you're visiting.
• Support and Team Collaboration: Respond to ad-hoc customer and internal escalations promptly (no regular on-call rotation). Assist your colleagues, share constructive feedback, and contribute to weekly syncs and daily Slack standups.

What Skills and Knowledge Will You Bring?

We do not require a perfect match with everything below; however, the more this describes you, the better of a fit you will be for this role.

• Experience
• Solid computer science background with 5+ years engineering experience including both backend and frontend.
• Proven expertise designing and operating distributed systems or data-intensive services.
• Track record of leading substantial pieces of work end-to-end, under ambiguity, with multiple stakeholders.
• Experience working directly with customers or senior stakeholders to shape technical solutions.
• Technical Mastery
• Deep proficiency in at least one production language (Java strongly preferred; 5+ years) and working comfort in at least one additional language.
• You value elegant code that is concise and readable.
• You'll pick up new tools and codebases as the work demands, and will likely end up working with modern Java, React, TypeScript, Kafka, Redis, GraphQL, Node.js, SentinelOne's own platform, and more.
• You enjoy writing modern Java (we love lambdas) and prefer composition to inheritance.
• You're comfortable weighing in on CAP theorem considerations, and are energized by selecting the data structure with the perfect trade-offs for a problem at hand.
• Domain Familiarity
• Experience in the cybersecurity domain is strongly preferred. (think SIEM, EDR/XDR, log pipelines, detection engineering, threat hunting, etc.).
• A Collaborative, Curious, and Practical Mindset
• You're energized by walking into an unfamiliar codebase and being genuinely useful in a week, and by leading others through the same kind of work.
• You believe a vague customer request is an interesting technical problem waiting to be reframed, and that "a problem well-stated is half-solved.
• You can translate between engineers and non-engineers (customers, executives, sales, product, etc.) without losing precision in either direction.
• You'd rather ship a well-thought-out 80% that solves the real problem than a perfect 100% six weeks late.
• You take mentorship seriously and enjoy seeing other engineers grow in their ability to solve harder problems.
• You take pride in clear written communication — tickets, design docs, customer runbooks, and executive briefings alike.
