From 2001 to 2003 he was a project manager in the Digital Taskforce, which served as the secretariat for the joint public-sector Digital Government project. Its purpose was to strengthen digitalisation through cooperation between central government, municipalities and counties.
From 2003 to 2005 he was a special adviser at the Ministry of Finance, working on municipal finance, social policy and health policy.

Return to the Ministry of Finance (2009–2010)
From 2009 to 2010 he returned to the Ministry of Finance as Head of Division in the Centre for Quality, Simplification and Management.
He worked on government efforts to simplify public administration and develop new approaches to management.

Rambøll Management Consulting and Rambøll Group (2010–2018)
In 2010 he returned to Rambøll Management Consulting as Senior Director.
He advised municipalities, ministries and international organisations on urban development, sustainable growth, governance and organisational development.

His responsibilities covered around 200 employees and annual revenue of approximately DKK 200 million.
He left Rambøll in 2018 following his appointment as a director at the City of Aarhus.
Director of Technical and Environmental Services, City of Aarhus (2018–)
His appointment as Director of Technical and Environmental Services was announced on 15 March 2018, and he took up the role in June that year. He has held overall administrative and managerial responsibility for a department of around 1,600 employees, covering urban development, physical planning, mobility, architecture, nature, climate and the environment.
The director is the principal administrative adviser to the responsible elected executive and a member of the city's executive management team. His tenure has coincided with continuing population growth, major urban development projects, climate transition requirements and increasing attention to the relationship between urban development, mobility, the environment and quality of life.
Strategy and organisational development
During his tenure, Technical and Environmental Services has carried out an organisational and strategic development process, establishing a shared mission, vision, political priorities and common leadership principles. This work aims to connect political ambitions, administrative priorities and day-to-day delivery.
Work has also focused on a more coherent executive and management structure, common leadership principles, stronger internal communication and cooperation across the organisation.
Climate and the green transition
Climate action has been a central area of work during his tenure.
The City of Aarhus adopted its Climate Plan 2025–2030 as part of efforts to reduce the municipality's overall greenhouse gas emissions.
The plan covers energy, transport, construction, nature, resources and food systems.
In summer 2026, a political majority adjusted the city's climate targets following difficulties in realising the original assumptions for carbon capture and storage. The revised target includes substantial reductions by 2030 and the ambition of becoming climate positive by 2035 at the latest.
Technical and Environmental Services has played a central role in preparing and implementing a number of these initiatives.
Mobility and urban development
Another major area of work has been the development of Aarhus's transport system and urban structure.
In 2024 a broad political majority agreed on a green mobility plan, subsequently developed into a plan containing more than 50 initiatives.
The plan covers public transport, cycling infrastructure, urban spaces, traffic management and reductions in transport-related climate impacts.
In parallel, the department has worked on major development areas including Aarhus Ø, Sydhavnen, the former county hospital and Pier 3.
These projects have involved questions of urban quality, architecture, sustainability, housing, infrastructure and the relationship between established and new neighbourhoods.
Leadership philosophy and professional interests
Seiding's leadership philosophy draws on values-based and relational leadership. Shared direction, trust, integrity and responsibility are central to organisational results.
His personal leadership principles emphasise clear priorities combined with substantial room for local leadership.
His approach encourages different professional perspectives to challenge one another through dialogue and allows decisions to change in response to well-founded professional arguments.
A recurring theme is leadership in politically governed organisations, particularly the relationship between advice to elected representatives, strategic management and the ability to translate broad ambitions into practical action.
His work also focuses on sustainable societal development and the connections between the built environment, the green transition and quality of life.
Board positions and public roles
Seiding has been involved in the Association of Municipal Technical Directors (KTC), which represents municipal leaders in technical and environmental services.
In August 2022 he became chair of KTC's Central Denmark regional chapter, and in November 2023 he joined the national board.
Since 2024 he has been deputy chair of KTC, with professional responsibilities including digital government, climate, energy and resources.
He has also participated in advisory board work at Aarhus University and held board positions in companies within the Kredsløb group and at Rambøll.
Publicly registered board roles in 2026 include chair of Aarhus Kommunes Klimaselskab ApS and a seat on the board of Pier 3 P/S.
Publications and professional communication
Seiding has addressed public leadership, governance and strategic development through professional publications and articles.
In 2009 DJØF Publishing published Når måling giver mening – Resultatbaseret styring og dansk velfærdspolitik i forvandling (When Measurement Makes Sense: Performance-Based Management and the Transformation of Danish Welfare Policy). The publication discusses performance-based management and the relationship between documentation requirements, professional judgement and learning in the public sector.
His later writing has included strategy and leadership in politically governed organisations and the organisational conditions for putting strategic decisions into practice.
