Junior Algorithmic Shift Power Trader

Full-time (shift-based, including weekends)
London – Paddington

At Quark, we bring together talented people across energy trading, quantitative research, and software engineering to build algorithmic trading systems for electricity markets.

We are a proprietary trading firm focused on developing algorithmic and high-frequency trading strategies in power markets, an area where automation is rapidly transforming how electricity markets operate.

Quark was founded in 2020 as a joint venture between Liger Investments and Habitat Energy.

Liger Investments is a global proprietary trading firm specialising in algorithmic trading of futures and derivatives across major exchanges. Habitat Energy optimises flexible energy assets across the UK, Australian and US electricity markets and brings deep electricity market and data science expertise. Habitat Energy is a portfolio company of Quinbrook Infrastructure Partners.

We are looking for analytical, curious and highly motivated individuals who want to work at the intersection of quantitative analysis, software systems and real-time trading.

This is a hands-on trading role where you will learn how automated strategies interact with live electricity markets, work closely with traders and quantitative developers, and contribute to improving our trading performance.

Key Responsibilities

Monitor and manage the real-time execution of algorithmic trading strategies
Manage open market risk when required
Work with senior traders and quantitative developers to adjust strategy parameters and identify new trading opportunities
Test and evaluate trading strategies using historical and live market data
Perform post-trade analysis to understand performance and identify improvements
Contribute ideas to improve trading tools, monitoring systems, and processes
Produce structured market analysis to support trading decisions

Working Pattern

This is a shift-based role and requires:

Working either Saturday or Sunday
Four additional weekdays (Monday–Friday)
Scheduled early morning or late evening shifts
Selected Bank holiday coverage

The role is based in our Paddington office in London.

Part of the initial training will take place in Kraków, where our development team is based.

Candidates should apply only if they are comfortable with this working pattern.

Requirements

We are looking for candidates with strong analytical ability and the motivation to operate in a fast-moving, data-driven trading environment.

Essential:

Strong numerical and problem-solving skills
Ability to analyse data and reason about complex systems
Python programming experience
Ability to communicate complex ideas clearly and concisely
High level of attention to detail and accountability

Typical background:

Degree in Mathematics, Physics, Engineering, Computer Science, Economics or another quantitative discipline
Strong academic performance

Nice to Have

Understanding of electricity market dynamics, particularly UK or European prompt power markets
Experience working with data analysis or statistical modelling
Familiarity with trading, probability, or risk-based decision making
Interest in strategic games involving probabilistic thinking (e.g. poker, strategy games)

What We Offer

Salary: £45,000 -£ 50,000 + performance bonus
Direct exposure to live algorithmic trading systems
Opportunity to work closely with experienced traders, quantitative researchers, and engineers
A collaborative and intellectually challenging environment
Significant opportunities for learning and career development

Eligibility
