What They Do
Ingrid Capacity is an energy technology company specializing in the development and operation of grid flexibility infrastructure, with a core focus on battery energy storage systems and advanced optimization software (source: ingridcapacity.com). Founded in 2022, the company designs and structures innovative energy supply and capacity solutions, including tolling and floor agreements, to support constrained electricity grids (source: ingridcapacity.com). Their proprietary trading and optimization platform enhances grid utilization and stability by managing flexible assets across Europe, targeting system operators, energy users, and power producers in grid-constrained markets (source: notified.com). Ingrid Capacity positions itself as a Nordic leader in energy storage, actively supporting electrification through scalable battery assets and energy contracting structures (source: business-sweden.com).
Projects & Track Record
Ingrid Capacity operates more than 200 MW/MWh of battery energy storage and has approximately 270 MW/340 MWh under construction in Sweden and Finland, with a development pipeline exceeding 6 GW across Europe (source: business-sweden.com). A flagship project is the Nordics’ largest battery energy storage system currently in the design phase in Horsaryd, Sweden, with a planned capacity of 100 MW/200 MWh (source: ingridcapacity.com). Another key milestone was the 2026 opening of a battery storage facility in Rättvik, developed in partnership with SEB Nordic Energy Fund and Locus Energy, aimed at enhancing grid flexibility in western Sweden (source: ingridcapacity.com). The company has also expanded cross-border, including a strategic partnership with French developer Wattmen and a collaboration with Germany’s Energiequelle to develop 200 MW of grid-connected battery systems, where Ingrid manages financing, operation, and optimization (source: windbranche.de).
Recent Developments
In 2026, Ingrid Capacity announced it had doubled its battery storage portfolio, surpassing 1 GWh in capacity, reflecting rapid scaling of its operating and construction assets (source: ingridcapacity.com). The company also formalized its corporate leadership with appointments including Axel Holmberg as CEO and Erik Sellstedt as CFO, signaling maturation of its organizational structure (source: ingridcapacity.com). Strategic partnerships have been a focus, such as the February 2026 alliance with Wattmen to expand in continental Europe and the late 2025 collaboration with Energiequelle in Germany to develop large-scale battery storage projects (source: ingridcapacity.com). These moves support Ingrid’s ambition to broaden its footprint beyond the Nordics into France, Poland, and Germany (source: business-sweden.com).
Working There
Ingrid Capacity offers roles primarily in engineering, grid optimization, energy markets and trading, business development, finance, communications, and project development, reflecting its technical and commercial focus on intelligent grid infrastructure (source: ingridcapacity.com). The company’s culture emphasizes fast growth, European expansion, and specialization in cutting-edge energy storage technologies rather than traditional utility models (source: linkedin.com). Headquartered in central Stockholm, Ingrid Capacity maintains a dynamic environment suited for professionals interested in shaping the future of flexible energy systems across Europe.

Job Description
Ingrid was born out of a simple belief: the energy transition must move faster and work smarter. We're pioneers at the forefront of the global energy transition - pushing boundaries, turning bold ideas into reality, and solving the problems that matter most.
The INtelligent GRID of tomorrow needs to absorb and release more power. We develop, build and operate high-performance batteries - the lungs of modern energy infrastructure - enabling a more flexible and resilient energy supply across Europe. With 500 MW already deployed across the Nordics and rapid expansion into continental Europe, we manage, optimise and trade both our own assets and those of third parties through our sophisticated tech platform, making every battery - and the entire grid - stronger.
About the role
We're growing our BESS and renewable trading team and looking for a power trader to take operational ownership of our trading algorithms across day-ahead auctions, Nordic ancillary capacity auctions, and the continuous intraday market. This is a hands-on, market-facing role: you'll be the person monitoring the algorithms and trade execution, tuning parameters, and making sure our algorithms behave as intended in live markets, pairing strong market knowledge and technical fluency with disciplined execution - rather than building models from scratch.
You'll also contribute to the development of new trading strategies and work in close cooperation with our Asset Management, Algo, Quant, and Engineering teams to keep trading activity aligned with the broader portfolio and technical roadmap.
The role requires operational shift work, including weekend coverage, to ensure our trading algorithms are monitored across all trading and delivery hours.
What you'll do
- Monitor and operate BESS trading algorithms in real time across day-ahead, ancillary, and intraday markets - adjusting parameters and intervening or overriding the automated engine when needed, in response to changing market conditions or unexpected events (e.g. price anomalies, grid events or asset outages).
- Validate that bids generated by the optimization engine are correctly submitted to day-ahead auctions and Nordic ancillary capacity auctions (FCR, aFRR, mFRR).
- Reconcile and validate trade results against expected outcomes, flagging and investigating discrepancies.
- Track and report on algorithm performance across all traded markets, identifying where live performance deviates from theoretical/backtested expectations.
- Act as the operational point of contact for settlement, imbalance, and BRP-related matters, including day-to-day interactions with TSOs and other market counterparties.
- Support the algo and quant teams in developing and refining new trading strategies across ancillary, day-ahead, and intraday markets, contributing a trader's-eye view of market behaviour and edge cases.
- Act as the operational link between live trading and the Asset Management, Algo, and Engineering teams, keeping trading activity aligned with portfolio, technical, and strategic requirements.
- Back test algorithm performance and contribute to the evaluation framework used to assess new strategies before deployment.
Your qualifications and experience
- Prior experience in European physical power markets is highly valued - trading desk, portfolio management, or similar operational role.
- Solid understanding of wholesale power markets (day-ahead, intraday, balancing) and how Nordic ancillary service markets function (FCR, aFRR, mFRR).
- Understanding of BESS revenue streams and how they interact across markets.
- Good knowledge of the energy regulatory landscape, including REMIT, BRP obligations, settlement and imbalance processes, TSO market prequalification requirements, and day-to-day interactions with TSOs.
- Comfortable working with algorithmic and automated trading setups.
- Strong attention to detail, with the ability to work independently and make real-time decisions under pressure.
- Programming skills, particularly Python, for analysing algo output and reviewing back tests - not required, but a strong plus.
- Bachelor's or Master's degree in a relevant field (e.g. engineering, business, finance, physics, energy systems), or equivalent practical experience.
Your personal skills
Beyond technical experience, we're looking for someone with the right mindset and a genuine passion for renewable energy, including:
- Ownership and reliability - taking full responsibility for the algorithms and trades to drive commercial performance across Ingrid's portfolio.
- Diligence and attention to detail - catching the bid or result that doesn't look right, every time.
- Analytical and structured thinking - spotting patterns in performance data and grounding them in real market behaviour.
- Communication and collaboration - clear handovers between shifts, and generous knowledge-sharing with the algo and quant teams.
- Adaptability and agility - comfortable with a shift schedule that includes weekends, and with markets that don't always behave as expected.
Why join us?
At Ingrid, we're pioneers at the forefront of the global energy transition - pushing boundaries, turning bold ideas into reality, and solving what matters most. Our culture is built on Bold Impact Curious Grit Inspiring Collaboration. We believe a thriving organisation runs on trust, growth, and learning from mistakes - and that wellbeing matters as much as work. From lunch & learns to social activities, we make space to connect, recharge, and thrive together.
Next step
We'll make selections on an ongoing basis and finalise the recruitment as soon as we've found the perfect match. This process will run over summer vacations and we will keep everyone involved updated on our expected timeline.
We look forward to hearing from you!
