Information Security Engineer - DLP

Palantir Technologies • Washington, DC

2d • $145,000 - $200,000 • Onsite

About The Position

Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.

We're looking for someone who has spent years thinking adversarially about how sensitive data moves, leaks, and gets exfiltrated — not just enforcing policies, but understanding every layer of how data can be abused, detected, and protected. If you've built content inspection pipelines, tuned classification policies against real insider threat cases, or reverse-engineered an exfiltration channel that bypassed existing controls, this is the team you want to be on.

As an Information Security Engineer focused on Data Loss Prevention, you'll own the security of Palantir's global data protection program. Your team runs 24/7 prevention, detection, and investigation of data security events across our entire environment. The adversaries we face are sophisticated. We need someone who is more so.

Requirements

• Deep, working knowledge of DLP architecture: endpoint agents, network inspection, cloud API integrations, policy engines, and content-aware detection across structured and unstructured data.
• Hands-on experience investigating and detecting data exfiltration across the full kill chain — from reconnaissance and staging through exfiltration via web, email, removable media, and cloud sync channels.
• Familiarity with common evasion techniques (encoding, steganography, covert channels, cloud storage abuse) and, critically, what they leave behind.
• Experience building and maturing DLP programs: classification taxonomies, policy tiering by data sensitivity, incident workflow design, and false-positive reduction methodologies.
• Thorough understanding of data security architecture: content inspection techniques, regular expression and fingerprinting-based detection, optical character recognition (OCR) for image-based data, and contextual policy enforcement.
• Ability to assess data flows across complex environments — SaaS, IaaS, on-premises, and hybrid — and identify where controls are absent or insufficient.
• Proficiency with log analysis and forensic investigation tools to reconstruct data movement and user behavior across endpoints and network infrastructure.
• Experience building telemetry pipelines and detections on top of raw DLP event data beyond out-of-the-box vendor alerting.
• Proven track record writing high-fidelity detection logic for data exfiltration and insider threat scenarios, not just tuning vendor signatures.
• Experience leading complex incident response investigations involving insider threats, compromised credentials being used to stage and exfiltrate data, or sophisticated external actors.
• Strong forensic fundamentals across endpoint artifacts, network captures, and cloud audit logs relevant to data movement investigations.
• 5+ years of hands-on security experience, with the majority focused on data loss prevention, data protection, or insider threat programs.
• Proficiency in Python or a scripting language of your choice for detection development, policy automation, and forensic tooling.
• Active TS/SCI security clearance, or eligibility and willingness to obtain one.
• A portfolio of real work: policies you've designed, detections you've written, investigations you've led, or programs you've built.

Nice To Haves

• Experience with cloud-native data security controls across major IaaS and SaaS platforms, and hybrid architectures that span on-premises and cloud data stores.
• Prior work in insider threat programs, adversary simulation, or offensive security research — especially focused on data exfiltration tradecraft.
• Public contributions: conference talks, blog posts, or open-source tooling related to data protection or insider threat detection.

Responsibilities

• Own the security posture of Palantir's DLP estate — policy architecture, classification standards, and ongoing validation that those standards hold.
• Reduce data exposure risk across the environment: audit and remediate misconfigured policies, coverage gaps, over-permissioned data flows, shadow IT channels, and enforcement blind spots.
• Evaluate, deploy, and own the configuration of data protection tooling across endpoint, network, and cloud vectors: content inspection, data classification, user activity monitoring, and enforcement controls.
• Build and maintain automation for data security operations — policy tuning pipelines, alert triage workflows, access reviews, and data handling hygiene.
• Partner with Identity, Infrastructure, and Legal teams to drive architectural improvements: data classification frameworks, acceptable use enforcement, cloud data governance, and insider threat program integration.
• Translate findings from assessments and incident investigations into durable fixes — policy changes, architectural improvements, and program updates that reduce recurrence.

Benefits

• Employees (and their eligible dependents) can enroll in medical, dental, and vision insurance as well as voluntary life insurance
• Employees are automatically covered by Palantir’s basic life, AD&D and disability insurance
• Commuter benefits
• Take what you need paid time off, not accrual based
• 2 weeks paid time off built into the end of each year (subject to team and business needs)
• 10 paid holidays throughout the calendar year
• Supportive leave of absence program including time off for military service and medical events
• Paid leave for new parents and subsidized back-up care for all parents
• Fertility and family building benefits including but not limited to adoption, surrogacy, and preservation
• Stipend to help with expenses that come with a new child
• Employees can enroll in Palantir’s 401k plan
