Full Stack Developer (AWS, NextJS, Python)

• Architect B2B SaaS Infrastructure: Design and implement multi-tenant architectures using AWS CDK, ensuring strict data isolation and scalable feature-tiering.
• Full Stack Development: Build high-performance, type-safe web applications using NextJS and TypeScript, powered by Python backends.
• Revenue Engineering: Own the lifecycle of paid upgrade paths, from Stripe integrations to granular feature-flagging and RBAC (Role-Based Access Control).
• API Excellence: Design, document, and maintain robust APIs that interface with both our edge devices and third-party industrial systems.
• Scale with CDK: Use Infrastructure as Code to manage our growing AWS footprint, ensuring deployments are repeatable, versioned, and secure., * Reliability: Maintain 99.99% uptime for the SaaS platform and alerting engine.
• Velocity: Deliver production-ready B2B features (e.g., new billing tiers or reporting modules) from concept to rollout in rapid cycles.
• API Performance: Maintain <100ms P99 latency for critical API endpoints.
• Deployment Integrity: Zero-downtime migrations and schema updates across multi-tenant environments.

30/60/90-day plan:

30 Days - Deep Dive & Integration:

• Map the existing AWS infrastructure and deploy a minor feature update via CDK.
• Audit the current B2B checkout/upgrade flow and identify three friction points.
• Contribute your first full-stack PR (NextJS + Python) to the core monitoring dashboard.

60 Days - Feature Ownership:

• Lead the development of a new "Premium" feature tier, including backend logic and frontend UI.
• Optimize a core API service to handle a 2x increase in concurrent device telemetry.
• Implement automated E2E testing for the critical alert-notification path.

90 Days - Platform Leadership:

• Refactor a major component of the multi-tenant architecture to improve scaling efficiency.
• Design and launch a public-facing API for enterprise customer integrations.
• Set the standard for the stack: mentor teammates on CDK best practices and NextJS optimization.

• 5+ years of professional experience in Full Stack Engineering.
• The Hacker Mindset: You must have personal projects, side hustles, or open-source contributions that you can demonstrate. If you only code during office hours, you are not a fit. We look for people who are always on, always hacking, and always learning.
• AWS Master: Deep experience with AWS CDK, Lambda, AppSync/API Gateway, and DynamoDB.
• Modern Stack: Expert-level proficiency in TypeScript, NextJS, and Python.
• SaaS Architecture: Proven experience building B2B SaaS products (feature-gating, subscription management, complex permissions).

Nice-to-Haves:

• Experience with IoT data visualization or real-time streaming (WebSockets, MQTT).
• Prior experience in a high-growth startup environment.
• Knowledge of Tailwind CSS and modern UI/UX principles.
• Experience with Stripe API or similar billing engines.

* High-Impact Ownership: Your code prevents disasters in the real world. This ain't your typical B2B SaaS * Fast & Flat: No middle management, no unnecessary meetings. Just building. * Equity: Meaningful equity participation in a company protecting global industries. * Elite Peers: Work alongside world-class CV/ML engineers in a high-intensity environment.
