Junior Energy Data Scientist - Energy Data & Automation, MSB
About the job
- You have initial experience in Tier 1 or Tier 2 consulting, high-growth startups—ideally in operations or process optimization—or project management, and a completed degree in a relevant field.
- You have experience or a strong interest in data analysis, automation, and artificial intelligence/large language model agents, such as Python, application programming interfaces, and handling large datasets.
- You have a strong numerical and data understanding and enjoy systematically investigating data-quality problems using data.
- Ideally, you have experience in the energy industry or market communication, including market communication, metering-point operations, tenant electricity, and balancing, or a clear willingness to learn these areas quickly.
- You work in a structured and conscientious manner and verify that results are substantively correct.
- You take ownership of an area rather than merely processing tasks and want to assume responsibility in a fast-paced, founder-adjacent environment.
- You are based in Berlin or willing to relocate; the office is the primary workplace.
- You speak German and English fluently.
- Analyze meter readings, meter values, and dispatch jobs for patterns, outliers, and recurring root causes.
- Translate findings into artificial-intelligence agents that independently diagnose errors and suggest or implement solutions.
- Act as the subject-matter driver of the metering-point-operations application by identifying missing features, specifying them, and developing them into the product.
- Bring projects to billing readiness each month by correcting missing or implausible meter values, creating substitute values from reference profiles, masking values, and having values recalculated.
- Create dispatch jobs, monitor their status, and validate the data after each fix.
- Work daily in partner and internal metering-point-operations applications according to standard metering-point-operations processes.
- Own all energy-data tickets internally and externally, from intake through prioritization to resolution, and act as the escalation point for complex cases.
- Monitor metering-point-operations mailboxes, assign market-partner messages to the correct cases, and ensure that deadline-relevant communication is not missed.
- Train interns and working students in processes, tools, and the metering-point-operations documentation, support them until they work independently, and keep the documentation current.
- Ideally, experience in the energy industry or market communication, including market communication, metering-point operations, tenant electricity, and balancing.
About the company
VREY is a Berlin PropTech company that helps landlords enable solar power for multi-family buildings. It handles planning, installing photovoltaic systems, and the operational setup, including a digital platform that automates legally compliant billing to tenants. As a metering point operator (wMSB), it also manages contracts with other energy providers, removing the supplier obligation from landlords and allowing tenants to buy solar energy directly (potentially lowering bills by up to 20%). Its goal is to scale communal solar use, support building decarbonization, and increase property value through tenant-accessible clean energy.

Simplify's Take
What believers are saying
- Germany’s June 2026 Energy Sharing rules expand local-solar policy momentum beyond §42b.
- VREY’s August 2026 hiring spree spans enterprise sales, operations, product, and finance roles.
- The April 2026 funding extends runway for platform automation and new building deployments.
What critics are saying
- §42b EnWG still demands 15-minute metering, contracts, and allocation logic, creating rollout friction.
- VREY’s model depends on landlord adoption; slow conversion leaves enterprise hiring underutilized by 2027.
- E.ON, Enpal, and local metering operators can bundle similar services faster, crushing differentiation.
What makes VREY unique
- VREY combines PV installation, wMSB metering, and billing for §42b buildings.
- The April 2026 €3.3 million seed round backs Rubio, HTGF, and kopa.
- VREY reports over 200 residential buildings across all 16 German states.

↑ 7%Berlin-based startup VREY has secured €3.3 million in seed financing to scale its solar power solutions for multi-family homes. The company specialises in bringing photovoltaic systems directly to urban residential buildings. VREY is already active in over 200 buildings, demonstrating early traction in the multi-family housing sector. The funding will support the company's expansion efforts as it works to increase solar power adoption in urban residential properties. The investment highlights growing interest in decentralised renewable energy solutions for apartment buildings, where traditional solar installations have historically been more challenging to implement compared to single-family homes.
Styx, a Mannheim-based investment firm, has invested in Vrey, a Berlin start-up focused on solar projects and communal building energy supply. This partnership aims to overcome the challenges of existing tenant electricity models. Styx specializes in early-stage investments in start-ups that promote more sustainable cities and buildings.
