Freelance Detection Engineer Jobs in California (NOW HIRING)

Freelance Detection Engineer information

What is a freelance detection engineer?

A Freelance Detection Engineer is a cybersecurity professional who works independently to design, implement, and optimize systems that detect security threats within an organization's network or applications. They typically create detection rules, manage security information and event management (SIEM) tools, and respond to incidents as needed. Unlike in-house engineers, freelance detection engineers provide their expertise on a contract or project basis, often working with multiple clients to improve their security posture and threat response capabilities.

What skills and qualifications are needed to thrive as a freelance detection engineer?

To thrive as a Freelance Detection Engineer, you need a strong background in cybersecurity, threat detection, and incident response, often supported by experience with SIEM platforms and relevant certifications like GIAC or OSCP. Proficiency with technical tools such as Splunk, Elastic Stack, MITRE ATT&CK framework, and scripting languages like Python is crucial. Critical thinking, clear communication, and self-motivation are essential soft skills for excelling in remote and dynamic environments. These skills and qualities are vital for proactively identifying threats, delivering effective solutions to clients, and adapting to evolving security landscapes.

How do freelance detection engineers typically collaborate with client security teams during an engagement?

Freelance Detection Engineers often work closely with client security teams to understand their unique threat landscape, existing detection capabilities, and specific goals. Collaboration usually involves regular check-ins, sharing findings, and providing actionable recommendations for improving detection rules or processes. Communication is key, as freelancers must integrate their expertise with the client's workflows and tools—often remotely and across different time zones. This partnership ensures that detection strategies are both technically sound and aligned with the client's operational needs.

What is the difference between Freelance Detection Engineer vs Security Analyst?

AspectFreelance Detection EngineerSecurity Analyst
CredentialsCertifications like GIAC, CISSP, or CEH; relevant technical skillsCertifications such as CISSP, CISA, or GIAC; security knowledge
Work EnvironmentIndependent, project-based, remote or on-siteIn-house or consulting roles within organizations
Industry UsageFreelance cybersecurity projects, threat detection, and consultingMonitoring, analyzing, and responding to security incidents

Freelance Detection Engineers focus on providing specialized threat detection services on a project basis, often working independently. Security Analysts typically work within organizations to monitor and respond to security threats regularly. Both roles require similar certifications and technical skills but differ mainly in work setting and employment structure.

Job description

Who we are

Gatik, the leader in autonomous middle-mile logistics, is revolutionizing the B2B supply chain with its autonomous transportation-as-a-service (ATaaS) solution and prioritizing safe, consistent deliveries while streamlining freight movement by reducing congestion. The company focuses on short-haul, B2B logistics for Fortune 500 retailers and in 2021 launched the world's first fully driverless commercial transportation service with Walmart. Gatik's Class 3-7 autonomous trucks are commercially deployed across major markets, including Texas, Arkansas, and Ontario, Canada, driving innovation in freight transportation. 

The company's proprietary Level 4 autonomous technology, Gatik Carrier, is custom-built to transport freight safely and efficiently between pick-up and drop-off locations on the middle mile. With robust capabilities in both highway and urban environments, Gatik Carrier serves as an all-encompassing solution that integrates advanced software and hardware powering the fleet, facilitating effortless integration into customers' logistics operations.

    Process, clean, and validate large-scale LiDAR point cloud datasets.
    Extract and refine road-based linear and polygonal features.
    Annotate and validate 3D objects and roadway furniture.
    Perform topology validation of road networks (lane connectivity, intersection logic, turn constraints).
  • Software Engineering:
    Develop and maintain Python-based geospatial data processing tools (required).
    Contribute to performance-critical components using C++ (optional).
    Manage and process large spatial datasets using cloud infrastructure (Azure preferred).
  • Database and Spatial Queries: Work with PostGIS databases to perform advanced spatial queries, including intersection detection, geometry building/transformation, and query optimization.
  • Data Management & Collaboration:
    Support data migration, versioning, and format conversion (OSM, OpenDrive, Lanelet).
    Coordinate with remote freelancers and distributed contributors. Work closely with autonomy, perception, and planning engineering teams.

More about Gatik

Founded in 2017 by experts in autonomous vehicle technology, Gatik has rapidly expanded its presence to Mountain View, Dallas-Fort Worth, Arkansas, and Toronto. As the first and only company to achieve fully driverless middle-mile commercial deliveries, Gatik holds a unique and defensible position in the AV industry, with a clear trajectory toward sustainable growth and profitability.

We have delivered complete, proprietary AV technology - an integration of software and hardware - to enable earlier successes for our clients in constrained Level 4 autonomy.  By choosing the middle mile - with defined point-to-point delivery, we have simplified some of the more complex AV challenges, enabling us to achieve full autonomy ahead of competitors. Given extensive knowledge of Gatik's well-defined, fixed route ODDs and hybrid architecture, we are able to hyper-optimize our models with exponentially less data, establish gate-keeping mechanisms to maintain explainability, and ensure continued safety of the system for unmanned operations.
