Job description
At Stack Builders, we partner with clients to build high-quality, production-ready software with clear goals, strong engineering practices, and minimal waste.
For this engagement, we are supporting a client building AI-enabled automated cybersecurity and insurance platforms. The work focuses on turning well-defined requirements and validated prototypes into reliable, scalable SaaS systems, while shaping the next generation of automated risk analysis tools.
We are looking for a senior full-stack engineer who can take ownership of features end-to-end and work effectively in an AI-assisted development environment.
What You’ll Work On
Build a production system based on an existing React prototype
Implement:
- Interactive data visualizations
- Risk scoring and analysis logic
- Backend integrations and supporting pipelines
Collaborate on evolving data models as the product matures
Build frontend interfaces for an automated Security Operations (SOC) platform
Integrate with backend services handling telemetry, analytics, and automated workflows
Support systems designed for heavy background data processing in a B2B context
Early-stage implementation based on defined product direction
Frontend-heavy work (UI, UX, interactions) and backend-focused work (APIs, data handling, business logic)
You will spend more time directing, reviewing, and refining than typing every line yourself
You are expected to use AI to generate initial implementations and provide the AI with codebase context (existing patterns, schemas, conventions)
Critically evaluate AI output for correctness, edge cases, and maintainability
Required Experience
Senior-level experience building SaaS applications end-to-end
Strong proficiency in React and Python
Experience with API design and integration, databases, and data pipelines
Ability to work from:
- Clear PRDs
- Prototypes
- Defined data models
AI-First Mindset
- You are comfortable using AI coding tools (Claude Code, Copilot, Cursor, ChatGPT) as part of your daily workflow.
- You can direct AI with clear prompting, refine its output, and detect subtle correctness or security issues.
- You value AI as a productivity multiplier—not a crutch—and you never copy AI output blindly.
Ways of Working
- You speak English fluently or at a professional level.
- Your communication is clear, organized, and assertive.
- You can work a minimum of 4 hours overlapping with the US Eastern timezone for real-time collaboration with the client.
- You enjoy working in a small, senior, high-ownership team.
- You are eager to learn, grow, and have fun while addressing meaningful challenges.
Benefits
- 100% remote and flexible modality.
- A human-centered experience in a people-first company.
- Challenging, full-time, and long-term projects with globally admired companies.
- A strong learning culture and regular pairing sessions to build high-quality code while sharing knowledge.
- Opportunities for conference participation, OSS contributions, tutorials, blog posts, and technical talks.
- Exceptionally talented and passionate coworkers.
- Timely payments, with the flexibility to choose the payment date modality that best suits your needs.
- A Stack Builders community to support you and grow with you!
