Senior Backend Engineer, Precision Defense

About the role

As a Senior Backend Engineer on the Precision Defense team, you'll help build the systems that move our customers from reactive security toward proactive, evidence-based defense. The team operates across three closely related areas — Rapid Response, Tripwires/Deception, Security Controls/EDR, and Autonomous Defense — and you'll contribute to backend infrastructure that spans all of them. Depending on where you land within the team, your focus might include: analyzing and surfacing emerging vulnerability intelligence; building and scaling the workflows that help customers identify exposed assets and validate their defenses; deploying and improving deception signals that catch attackers in the act; or producing credible evidence that endpoint detection and response (EDR) controls are working as expected. Across all of these, the common thread is translating attacker-informed findings into measurable defensive outcomes for our customers. This is a high-impact role on a team that owns customer-facing security workflows, supports production incidents, and ships features that directly influence how organizations understand and close their defensive gaps.

Responsibilities

• Build and maintain backend APIs, ETL pipelines, and data processing systems that power Rapid Response, Tripwires, EDR effectiveness, and Autonomous Defense workflows.
• Design and implement GraphQL APIs to facilitate data interactions across product components.
• Develop event-driven services and distributed systems that support reliable, scalable security automation.
• Collaborate with frontend engineers, attack engineers, and product managers to deliver customer-facing features that communicate security findings clearly and actionably.
• Contribute to production reliability: monitoring, alerting, incident response, and debugging across ETL, deployment, and data-propagation workflows.
• Support safe, explainable, and reversible security automation — understanding that incorrect behavior in this domain can mean missed detections, noisy alerts, or false confidence for customers.

Requirements

• Bachelor's Degree in Computer Science, Computer Engineering, or related field.
• 7+ years of professional software engineering experience using modern object-oriented or functional languages (Python, Java, Go, Scala, C++, TypeScript, etc.).
• Experience building applications on cloud computing platforms such as AWS, Azure, or GCP, using container technologies such as Docker and Kubernetes.
• Expert proficiency in SQL.
• Experience in one or more of the following areas: EDR/endpoint telemetry and control validation; detection engineering and SOC/SIEM workflows; threat detection, deception systems, honeypots, or tripwire-style platforms; vulnerability intelligence and rapid response workflows.
• Familiarity with major EDR platforms (CrowdStrike, SentinelOne, Microsoft Defender) at the telemetry or API level.
• Understands detection logic, alert triage workflows, and how security teams consume and act on findings.
• Comfort translating attack behavior into measurable defensive outcomes.
• Expert proficiency in SQL and experience with relational (PostgreSQL) and graph (Neo4j) database architectures.
• Experience building GraphQL backends.
• Background in event-driven systems, distributed services, observability, and production reliability.

Benefits

• Inclusive Team: We value diversity and promote an inclusive culture where everyone can thrive.
• Growth Opportunities: Be part of a dynamic and growing team with numerous career development opportunities.
• Innovative Culture: Work in a collaborative environment that encourages creativity and out-of-the-box thinking.
• Hybrid & Remote Work: We embrace a mix of remote and hybrid work models depending on role and location, including our Chicago office, where some roles require regular in-office presence.
• Competitive Compensation: We offer competitive salary, equity and benefits. Our benefits include health, vision & dental insurance for you and your family, a flexible vacation policy, and generous parental leave.
