Job description

This is a hands-on, high-impact role for a deeply technical engineer who thrives at the intersection of software development, security infrastructure, and platform engineering.

What You’ll Do

• Lead end-to-end software development across complex security data pipelines from ingestion to canonical data stores and downstream consumers.
• Own system architecture for endpoint protection platforms, including authoring System Design Records (SDRs) and Architecture Decision Records (ADRs).
• Drive platform reliability through availability monitoring strategies, alerting frameworks, and infrastructure hardening.
• Design and build APIs and services including REST API optimization, policy evaluation engines, integration adapter registries, and projection/aggregation services.
• Set engineering standards across the team for code quality, design consistency, and documentation practices.
• Mentor and guide other engineers on team through PR reviews, sprint planning, and technical deep dives.
• Collaborate cross-functionally with security architects, platform teams, and partner engineering orgs to ensure clean system integration and dependency alignment
• Support on-call operations on a rotating schedule, including flexibility for major incidents across time zones.
• Leverage AI-assisted development tools to accelerate delivery, enforce engineering rigor, and support multi-language development.

What We’re Looking For

Required:

• 7+ years of core software development experience with mastery in multiple programming languages and platforms.
• Strong foundation in database engineering, API development, and data pipeline construction, including experience with event-driven architectures, and distributed systems
• Demonstrated ability to craft and deliver large, sophisticated projects across the full software lifecycle, including experience with products released for public consumption across multiple releases.
• Proven experience with infrastructure hardening and operational reliability (alerting, availability monitoring, MTTR reduction).
• Ability to design systems at scale including experience with architecture reviews, design documentation, and cross-team alignment; experience working with engineering teams, architects, and executive leadership to craft architectural vision and roadmap.
• Develops technical performance architecture that solves the most complex performance and scalability challenges, with the ability to drive long-term design strategies spanning multiple complex projects.
• Strong engineering process discipline: PR reviews, design reviews, sprint execution, and documentation; experience with Agile/Scrum methodologies and short release cycles
• Ability to provide mentorship to team members, supporting their understanding of architecture and aiding in their technical growth
• Skilled at fostering cross-functional technical collaboration to surface, elevate, and resolve critical issues effectively.
• Ability to deliver technical reports and performance presentations to customers and at industry events
