How to apply for Digital Interface Manager (f/m/x)

About IONITY

IONITY builds and operates a high-power charging network for electric vehicles across Europe, focused on making long-distance EV travel practical. The company sits at the intersection of energy, mobility, and digital services, so employees work on products that directly affect how drivers experience charging on the road.

About the role

This digital interface manager role owns the business side of IONITY's digital interfaces and connected services, acting as the primary business owner toward IT. You define requirements, coordinate feature delivery with development teams, and align stakeholders across marketing, legal, and controlling. The role matters because these interfaces are the main touchpoints between IONITY and its customers.

A typical day

A typical day may involve meeting with development teams on feature delivery, aligning with marketing, legal, or controlling on requirements and timelines, and reviewing tracking or reporting data for digital interfaces. You would also coordinate with external partners and document business requirements. Ask the interviewer for a concrete example of a recent week in this role.

Who IONITY is looking for

• Has experience managing digital products or interfaces from a business perspective, including writing requirements and defining tracking and reporting data streams.
• Can work as the central contact across marketing, legal, controlling, and IT, keeping priorities, timelines, and trade-offs clear to everyone.
• Has worked with external partners and interface management, coordinating launches and ongoing lifecycle activities.
• Combines analytical thinking with a customer-centric view, and is comfortable in a fast-paced environment with many stakeholders.

Tips for this application

• Read the job description carefully: it mentions P&G – Digital Platform Department, which may be a copy error. In your application, refer to IONITY's digital platform work rather than repeating P&G.
• Highlight concrete examples where you owned business requirements for a digital interface and defined data streams for tracking, reporting, or analytics.
• Name the cross-functional teams you have worked with (marketing, legal, controlling, IT) and describe how you handled conflicting priorities or trade-offs.
• Show experience with external partner or interface management, including coordinating a feature launch and managing its lifecycle afterward.
• Since the role is remote in Germany, state your location and confirm you can work within German time zones and travel if needed for stakeholder meetings.

What to cover in your cover letter

Focus on your experience as a business owner of digital interfaces toward IT. Describe how you have written and documented business requirements, including data streams for tracking and reporting. Give an example of coordinating a feature launch across marketing, legal, controlling, and development teams. Explain how you manage external partners and keep communication transparent across internal teams.

Research before applying

• IONITY's current charging network size, locations, and countries, and how its app or digital services support drivers.
• IONITY's recent news, partnerships, and any changes in ownership or strategy that affect its digital platform.
• The competitive landscape for EV charging in Europe, including other networks and their digital interfaces.
• Ask the interviewer to clarify the P&G reference in the job description and to describe the actual team structure and daily workflow.

Likely interview topics

Based on the job description, expect questions about:

• How you would define and document business requirements for a new digital interface, including tracking and reporting data streams.
• A time you aligned marketing, legal, controlling, and IT on a feature launch with competing priorities.
• How you manage external partners and interface management through a full lifecycle, from launch to ongoing updates.
• How you measure whether a digital touchpoint delivers value to customers and to the organization.
• Your understanding of IONITY's charging network and how digital interfaces affect the driver experience.

Common mistakes to avoid

• Ignoring the P&G mention in the job description. If you notice it, ask about it rather than assuming the role is at P&G.
• Applying with generic product management language instead of concrete examples of business ownership of digital interfaces and requirements documentation.
• Focusing only on technical skills and skipping evidence of cross-functional stakeholder management with marketing, legal, controlling, and external partners.
