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

What you need to know about the Belfast Tech Scene

If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
