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

Base360.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 Base360.ai.

If you’re passionate about automation, distributed systems, and building high-performance software end-to-end, you’ll thrive here.


What You’ll Build

As a senior engineer at Base360, 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.


Your Mission


Architect Core Services

Design and build APIs, data pipelines, and backend services that form the foundation of Base360.ai.


Build Automation at Scale

Develop microservices and event-driven workflows that orchestrate real-world processes across industries and platforms.


Own The Frontend 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 Base360.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.


You’re a Great Fit If You Have

* Strong experience with Node.js / TypeScript, Python (FastAPI), or equivalent backend frameworks
* Solid expertise in React or another modern frontend framework
* Deep familiarity with AWS, especially serverless (Lambda, DynamoDB, EventBridge, 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


Why You’ll Love Working Here


High Ownership

You’ll 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.


This Role Is Not for You If

* You want rigid structure or predictable routines
* You prefer planning over building
* You’re satisfied with “good enough”
* You’re not driven to master your craft
