Algorithmic Trading Developer
From market data to autonomous trading decisions in real time.
About Covolt
Smart energy deserves smart people.
Covolt is a fast-growing, technology-driven player in the energy market, operating at the intersection of data, algorithmic decision-making, and real-time trading.
We develop and operate systems that translate energy and market data streams into autonomous trading decisions within the short-term power markets, including Day Ahead, Intraday, and ancillary services such as FCR and aFRR.
Intraday price movements, day-ahead price signals, imbalance markets, and flexibility and reserve markets serve as the input for our algorithms. These systems independently determine whether to trade, in which direction, at what volume, at what price, and at what time, and automatically execute these decisions.
The basic premise is clear: people develop the intelligence, algorithms make the decisions.
Within multidisciplinary teams, data scientists, developers, and trading specialists collaborate on decision models, algorithms, and systematic trading strategies that create structural value in dynamic energy and commodity markets.
We are looking for an Algorithmic Trader Developer who will actively contribute to the development, testing, implementation, and optimization of this algorithmic decision-making process.
About the Role
You develop the logic. The algorithm takes action.
As an Algorithmic Trader Developer, you’ll work at the intersection of trading, data, algorithms, and technology. Together with data scientists and developers, you’ll develop the decision models and algorithms that independently determine when, where, how, and how much to trade within the short-term power markets.
This is explicitly not a role in which you continuously place orders manually. You will build the system that makes the trading decisions.
You translate trading hypotheses, market insights, and data into algorithmic decision logic. These models are tested, validated, and integrated into production, where they independently make and execute real-time trading decisions.
Particularly within the intraday market, our systems combine market data, order books, price movements, forecasts, production and consumption data, and external signals to provide a real-time view of the market.
For example, the algorithms determine:
- whether there is a trading opportunity;
- whether or not action should be taken;
- in which direction and in what volume;
- when and at what price an order is placed;
- when a position needs to be adjusted or closed;
- how risk, liquidity, and execution are taken into account.
In doing so, you'll be working on the entire decision loop:
Market Data → Signal → Decision Model → Trading Decision → Order → Execution → Position → P&L & Risk
The key question is not just “What’s happening in the market?”, but above all:
“What decision should our algorithm make now?”
What does your job actually entail?
You're building the intelligence behind autonomous trading
Your responsibilities will include, among other things:
- Developing and optimizing algorithmic trading strategies for Day Ahead, Intraday, FCR, and aFRR.
- Developing decision models that autonomously determine in real time which trading action should be executed.
- Designing signal logic, pricing logic, and execution logic.
- Developing models for trade/no-trade decisions, position sizing, timing, and order placement.
- Analyzing real-time market data, order book data, forecasts, and external signals.
- Research on market structures, price movements, volatility, liquidity, and order flow.
- Developing and testing predictive models and statistical trading signals.
- Translating trading hypotheses into production-ready decision logic.
- Building and improving real-time data pipelines and analytics tools.
- Integrating algorithms with trading systems, APIs, and execution engines.
- Conducting backtests, simulations, and scenario analyses.
- Validating strategies for P&L, risk, robustness, execution quality, and scalability.
- Analyzing slippage, latency, execution issues, and market anomalies.
- Monitoring and optimizing algorithms within the live trading environment.
- Identifying new market inefficiencies and translating them into new trading strategies.
- Contribute to the further development of the algorithmic trading stack.
- Collaborate with traders, data scientists, and developers throughout the entire strategy lifecycle.
- Iterate quickly between research, development, backtesting, and live trading.
So you're not just developing a model that makes a prediction, but a system that uses that prediction to make decisions and take action on its own.
This challenge is a good fit if you have the following qualities
You have strong analytical skills, a curiosity for technology, and are energized by developing systems that can make and execute decisions independently. You find it interesting to understand why a market moves, how to model that behavior, and how to translate that information into an algorithmic trading decision. You’re able to structure complex problems, formulate hypotheses, and translate them into models, algorithms, and concrete trading strategies.
You understand that a good model must ultimately not only be accurate but, above all, create value in a live trading environment.
In addition, you have:
- A university degree in a field such as Econometrics, Data Science, Computer Science, Mathematics, Physics, Engineering, or a similar technical field.
- Strong analytical, quantitative, and conceptual skills.
- An interest in algorithmic trading, financial markets, and quantitative modeling.
- Strong programming skills, preferably in Python.
- Experience with data analysis, statistics, and the development of models and algorithms.
- Understanding of software development, version control, and testing.
- Experience with APIs, databases, and real-time data streams is a plus.
- Experience with backtesting, simulation, or trading strategy development is a strong plus.
- I'm interested in how decision models and algorithms can make autonomous trading decisions.
- Familiarity with energy markets—particularly Day Ahead, Intraday, FCR, and aFRR—is a strong asset.
- You are independent, proactive, and results-oriented.
- You can clearly communicate technical and quantitative concepts to traders, developers, and data scientists.
Your Impact
You build the algorithms that determine when Covolt executes trades.
At Covolt, impact isn't about reports—it's about what happens in the market afterward.
As an Algorithmic Trader Developer, you'll develop systems that continuously analyze the market and can make trading decisions without manual intervention.
