About the Job

Requirements

  • 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 area.
  • You have experience or a strong interest in data analysis, automation, and artificial intelligence or large language model agents, such as Python, application programming interfaces, and handling larger datasets.
  • You have strong numerical and data understanding and enjoy systematically investigating data-quality problems using data.
  • Experience in the energy industry or market communication, including market communication, metering operations, tenant electricity, or balancing, is desirable; alternatively, you are clearly willing to learn these areas quickly.
  • You work in a structured and conscientious manner and verify that completed work is substantively correct.
  • You take ownership of an area rather than only processing tasks, and aim to develop your full potential in it.
  • You are intentionally seeking a fast-paced, founder-adjacent environment where you can take responsibility, build structures, and actively contribute to growth.
  • You are based in Berlin or willing to relocate.
  • You speak German and English fluently.

Responsibilities

  • Analyze meter readings, meter register values, and dispatch jobs for patterns, anomalies, and recurring causes of errors.
  • Translate analysis into artificial intelligence agents that independently diagnose errors and suggest or implement solutions.
  • Act as the functional driver of the metering operations application by identifying missing features from day-to-day operations, specifying them, and developing them into the product.
  • Bring projects to billing readiness each month by correcting missing or implausible readings, creating substitute values using reference profiles, masking values, and recalculating them.
  • Create dispatch jobs, monitor their status, and validate data after each fix.
  • Work daily in partner applications and the internal metering operations application, following standard metering operations processes.
  • Own all energy-data tickets for internal project and billing teams and external network operators, suppliers, and transmission system operators, from intake and prioritization through resolution; serve as the escalation point for complex cases.
  • Monitor metering-operations mailboxes, assign market-partner messages to the correct cases, and ensure deadline-critical communications are not missed.
  • Train interns and working students in processes, tools, and the metering-operations handbook, support them until they work independently, and keep documentation current.

Desired Qualifications

  • Company equity is offered as part of compensation.
  • A technology budget of €2,000 is provided.

About the Company

VREY

Turnkey communal solar energy for buildings

VREY (RE Joule GmbH) is a Berlin PropTech firm that provides solar power solutions for multi-family buildings. It plans, installs, and operates photovoltaic systems and runs the administrative side through a digital platform that automates billing to tenants under §42b EnWG, acting as a metering point operator. Landlords can sell solar power directly to tenants, while the platform handles contracts with energy providers for any remaining electricity, reducing supplier obligations and potentially lowering tenant costs and increasing property value. The goal is to expand communal solar use, support building decarbonization, and grow the value of rental properties by enabling tenant-verified clean energy.
