Job Title: Full Stack Software Developer III

Job Location: San Diego, CA 92129
Job Duration: 6 Months Contract

Estimate Date: (10/05/2026 to 04/04/2027)

Duties:

• Threat Reporting Experience (TRE) owns the front door for Threat Operations: the web portals and AI assistants that route security findings to the right owner and surface decision-grade insight for leaders.
• This is a temporary contingent role providing backfill engineering support for TRE during a staffing gap, working alongside the team’s engineers on the same FY27 roadmap.

What you’ll do:

• Contribute full-stack features (React front end, Python back end) to the unified Threat Ops portal, including migrating existing onboarding and request forms onto the platform’s product catalog.
• Help build and expose platform capabilities via the team’s Threat Ops MCP standard, supporting natural-language query access through the team’s AI assistants.
• Contribute to the Threat Ops Defect Hub, replacing the legacy Slack-based publishing workflow with a templated reporter flow (create, risk-score, validate, submit) and Jira integration.
• Support the team’s dashboard and metrics work, surfacing posture data such as false-positive rate, AI investigation coverage, and request volume from existing data sources.
• Participate in code reviews and follow the team’s Git-based workflow and coding standards.
• Debug and resolve defects and support deployment and maintenance of the services you touch.
• Collaborate with TRE engineers and Threat Ops stakeholders to turn well-scoped tickets into shipped customer-facing improvements with minimal ramp-up time.

Hybrid Schedule: Onsite 3 days per week. This role is not available as fully remote.

Skills:

Must haves:

• Solid understanding of object-oriented design and fundamental programming concepts.
• Professional experience with JavaScript/TypeScript and React HTML/CSS responsive UI.
• Professional backend development experience in Python.
• Familiarity with Agile development methodologies and Git-based code review workflows.
• Ability to work independently on well-scoped tasks with minimal onboarding time. This is a backfill role supporting an existing team’s roadmap not a multi-month ramp-up position.
• Strong problem-solving skills and a track record of delivering on assigned tasks. – Excellent verbal and written communication skills.

Nice to haves:

• Experience with AI/LLM-assisted development tools e.g. Claude Cursor for building or maintaining AI assistants.
• Knowledge of AWS or other cloud computing services.
• Prior exposure to cybersecurity concepts. Not required but useful given the domain.
• Familiarity with MCP Model Context Protocol or similar tool-exposure standards for AI agents.

Education:

• Bachelor’s degree in computer science software engineering or a related technical field or equivalent practical experience. Demonstrated full-stack delivery experience carries more weight than credentials.
