Senior Backend & Frontend Engineer – The Flex

Join the team building the automation engine powering the next generation of intelligent operations.

Base
360.ai is an automation platform designed to connect data, orchestrate workflows, and operate real‑world systems at global scale. We transform fragmented processes into clean, automated pipelines that move businesses faster, with less work, fewer errors, and smarter decision‑making.

We’re looking for a Senior Backend & Frontend Engineer to help architect and scale the core systems behind Base
360.ai. If you’re passionate about automation, distributed systems, and building high‑performance software end‑to‑end, you’ll thrive here.

As a senior engineer at Base
360, you’ll work across backend services, frontend interfaces, and cloud infrastructure to build the core platform that powers real‑time automation. You’ll design systems that handle millions of events, integrate with third‑party services, manage high‑volume data flows, and deliver intuitive user experiences. Your work will define how businesses automate, operate, and scale.

• Architect Core Services: Design and build APIs, data pipelines, and backend services that form the foundation of Base
  360.ai.
• Build Automation at Scale: Develop microservices and event‑driven workflows that orchestrate real‑world processes across industries and platforms.

  Experience:
  
  Create fast, clean, and intuitive interfaces that allow teams to control automations, monitor systems, and gain insights in real time.
• Engineer for Reliability: Design systems that are fault‑tolerant, observable, and able to withstand high‑throughput, multi‑region workloads.
• Integrate the Ecosystem: Connect Base
  360.ai to services like Stripe, Twilio, Airbnb, Hostaway, and other mission‑critical APIs to create a unified automation layer.
• Lead With Impact: Drive technical decisions, mentor other engineers, and help define engineering standards and long‑term architecture.

• Strong experience with Node.js / Type Script, Python (FastAPI), or equivalent backend frameworks
• Solid expertise in React or another modern frontend framework
• Deep familiarity with AWS, especially serverless (Lambda, Dynamo
  
  DB, Event Bridge, SQS)
• Strong understanding of distributed systems, microservices, and event‑driven architecture
• Experience building scalable, production‑grade APIs and real‑time systems
• A passion for automation, intelligent workflows, and simplifying complex processes
• A builder’s mindset – autonomous, fast, pragmatic, and product‑oriented
• The ability to lead initiatives and deliver high‑quality software end‑to‑end

• High Ownership: Shape the architecture, roadmap, and engineering culture of a platform built for global scale.
• Real‑World Impact: Your automations will power mission‑critical operations across industries.
• Small Team, Big Responsibility: Move fast, avoid bureaucracy, and build systems that matter.
• Technical Creativity: Freedom to experiment, iterate quickly, and explore ambitious solutions.
• Performance‑Driven Rewards: Competitive compensation with meaningful upside for exceptional talent.
• Remote‑First: Work from anywhere. We optimize for output, not hours.

• You want rigid structure or predictable routines
• You prefer planning over building
