Senior Software Developer (Remote)

We are seeking a Senior Software Engineer to develop trading systems and monitoring tools for our Liquid Air Energy Storage (LAES) plants and grid-stability operations.

This role is fully remote with no requirement for office presence. We support remote collaboration through modern development practices, code reviews, and virtual team coordination.

We value clear thinkers with strong engineering fundamentals who can reason about distributed systems, data integrity, and real-time control.

Python is our primary language (Rust a plus), but we prioritize problem-solving ability and software craftsmanship above specific language experience. Strong engineering fundamentals are more important than specific language expertise — we support a short (:3 week) Python ramp-up period for strong engineers.

Trading Systems Development

Design and implement automated trading systems for UK energy markets (day-ahead, intraday, balancing, ancillary services)
Build real-time bidding, dispatch optimization, and pricing algorithms for LAES assets
Integrate with grid operators and market platforms

Monitoring & Analytics

Develop monitoring dashboards, alerting systems, and operational analytics for plant performance
Build monitoring dashboards for LAES and stability island operations

Data Pipelines & Infrastructure

Create high-throughput data ingestion and streaming pipelines using Kafka and PostgreSQL / TimescaleDB
Work with data pipelines using Kafka and PostgreSQL (pg_partman, TimescaleDB)
Build microservices and APIs for trading platforms, market integration, and system control
Develop microservices connecting trading platforms and grid operators

Collaboration & Operations

Collaborate with DevOps and Data teams for deployment, monitoring, and production support

Requirements

Must Have

Core Engineering:

Strong software-engineering fundamentals — architecture, testing, and code quality
Proficiency in Python (or readiness to ramp up quickly within :3 weeks)
Experience with distributed systems, microservices, and RESTful APIs
Solid understanding of software design patterns and testing practices

Data & Streaming:

Hands-on experience with Kafka or similar streaming platforms
Strong SQL skills with PostgreSQL and time-series data processing
Familiarity with data-pipeline frameworks and real-time processing

Technical Operations:

Experience with Docker and containerized applications
Understanding of monitoring, logging, and observability practices
Proficiency in Git and Agile development workflows

Nice to Have

Rust experience
Exposure to energy markets, trading systems, or optimization algorithms
Interest in industrial control systems, IoT, or real-world operational data

Highly Desirable — Agentic AI Coding Experience

We value candidates who can build software using agentic AI coding systems. This is fundamentally different from using code completion tools or chat-based assistants.

What we're NOT looking for:

GitHub Copilot (code completion/autocomplete)
ChatGPT or similar chat interfaces for generating isolated code snippets
Any tool that only provides single-turn question/answer interactions

What we ARE looking for: Hands-on experience with agentic coding systems such as Claude Code, Codex (OpenAI's agentic coding tool), Open Code, or Cursor.

Ideal candidates will demonstrate:

Breadth of experience — proficiency with at least 2 agentic systems (experience with only one is insufficient)
End-to-end development — ability to design and build software from the ground up using these tools, not just generating isolated snippets
Multi-agent orchestration — demonstrated experience orchestrating multiple agents using skills, tools, and agent

coordination, not just one-shot problem solving

Deep system knowledge — familiarity with hooks, permission systems, MCP (Model Context Protocol) servers, custom skills and tool definitions, and context management

Benefits

Plenty of opportunities for learning and professional growth
B2b contract with a paid vacation
