Full job description

Applied Computing was founded in 2024 to build Orbital, a physics-informed foundation model for energy operations. We’re live across oil and gas, refineries, and petrochemicals, working towards our mission: sustainable abundance for a growing planet.

The hydrocarbon industry keeps the world running. But its complexity has left operators tied to legacy systems, making critical decisions on less than 10% of available data. We built Orbital to change that. It’s a foundation model built specifically for energy that lets companies use AI at scale, harnessing all of their operational
data and optimising in real time for any metric. Decisions get faster, operations get safer, and carbon intensity falls.

We’ve raised over $32 million, including one of the largest seed rounds for an
AI company in the UK. We’re just getting started

As a Senior Full Stack Engineer on the Core AI team, you will build the platform that makes Orbital a scalable product. You will own the internal application layers, developer facing APIs, shared UI components, and integration frameworks that power every Orbital deployment.

This is a product engineering role focused on building reusable systems. You will collaborate with AI research, Infra, and software teams to translate complex industrial workflows into reliable system components and intuitive user interfaces.

Your work will define how users interact with Orbital across control rooms, engineering teams, and cloud-based environments.

What Success Looks Like

Orbital ships with high-quality dashboards and interfaces that users rely on daily
Core APIs and services provide stable, well-documented contracts for AI, data, and automation features
Frontend and backend codebases are modular, well-structured, and easy to extend
Releases are frequent, reliable, and backed by strong CI/CD pipelines
Features scale from one deployment to many without site-specific rework or bespoke

engineering

Requirements

Strong software engineering fundamentals (data structures, algorithms, complexity)
Solid understanding of system design patterns and architectural trade-offs
Strong proficiency in JavaScript / TypeScript
Experience building complex applications in React or Svelte
Ability to design reusable UI components and frontend architecture
Python for APIs, orchestration, and data integration
Backend experience with Node.js, FastAPI, Express, or similar frameworks
Experience designing and maintaining API-driven systems
Experience building containerised microservices using Docker and Kubernetes
Familiarity with distributed systems and event-driven architectures
Experience with message brokers such as Kafka or RabbitMQ
Comfortable working in Linux environments for debugging and performance tuning
Hands-on experience with AWS (EKS, S3, IAM, CloudWatch, networking fundamentals)

Product & Engineering Mindset

Comfortable operating in a fast-moving product environment with evolving

requirements

Strong collaboration skills across AI, infra, and product teams
Bias toward reliability, resilience, and long-term maintainability
Ability to design systems that scale across customers, sites, and industrial verticals
Comfortable shipping on a bi-weekly release cadence

What This Role Is Not

Not a pure frontend or UI-only role
Not infrastructure-only or DevOps-focused
Not a research or modelling role
Not a one-off project engineer; this role builds core platform primitives

1. Full Stack Product Development

Build features across the product stack: data access, backend services, APIs, and UI

layers

Develop backend logic that exposes:

o Time-series forecasts
o Physics-based model outputs
o LLM and agent outputs
As stable product features

Create internal tools and workflows that support multiple engineering and operational use cases without custom deployments
Ensure all application layers meet strict standards for:

o Reliability
o Security
o Observability
o Performance
Across cloud and on-prem environments

2. Platform & Microservices Architecture

Design and implement containerised microservices running in Kubernetes clusters
Create shared services and libraries that enable reuse across Orbital verticals
Define API boundaries and service contracts that allow AI and infra layers to evolve

independently

3. Core Platform Engineering

Collaborate with Product, AI Research, ML Engineering, and Infra teams on:

o Product requirements
o Long-term platform architecture

Build interface layers that expose inference, physics-based reasoning, and optimisation

as first-class platform capabilities

Implement abstractions for:

o Data ingestion
o Inference orchestration
o Scheduling
o Monitoring and health checks

Establish design patterns and engineering standards that unify the Orbital ecosystem

4. Software Engineering Excellence

Write clean, modular, maintainable code across frontend and backend systems
Set up and improve CI/CD pipelines for:

o Automated testing
o QA
o Rapid, safe releases

Participate in code reviews and architectural discussions
Leverage modern agentic coding tools to increase velocity while maintaining

correctness and readability

Benefits

Competitive salary and benefits
Ability to work from the office or remote
Employment contract in UK or India, EOR or contractor options available in other jurisdictions
Exciting high traction AI product
