About

From the pit wall to the workshop.

I'm Sia Linnemann, a motorsport data engineer and race strategist. Through SLiQ Engineering I support race teams at the track with data, strategy and session support, and in the workshop with engineering and documentation work.

I've worked across GT4, Porsche Carrera Cup, endurance racing and historic Formula 1, and I'm completing a BSc in Automotive Engineering with a minor in Motorsport Engineering at Fontys. Before engineering, I spent more than 1,000 hours in the pit lane as a race official, so I know how a race weekend runs from both sides of the pit wall.

What I bring to your team

Mainly trackside, for single events or a full season. Between events, I also take on engineering work in the workshop or factory.

At the track

Data

Data engineering

Getting the right data from the car and turning it into decisions the team and driver can act on.

  • Data acquisition and channel checks
  • Telemetry and video analysis
  • Driver coaching from data
  • Session reports and setup evaluation
Strategy

Race strategy

Clear calls under pressure, built on preparation done before the weekend starts.

  • Fuel, tyre and stint planning
  • Pit-stop timing and driver rotations
  • Run plans for endurance races
  • Live timing and communication with race control
  • My own race strategy tool to support decision making
Trackside

Trackside support

Keeping the weekend running smoothly, from session planning to the pit lane.

  • Session planning and team coordination
  • Tyre preparation and pressures
  • Driver communication and team management
  • Mechanical support in the garage and during pit stops

Workshop & engineering support

Engineering support behind the scenes: documentation, CAD, parts and tools that keep a programme running. I currently do this at Parabolica Racing on historic BMW Sauber and BMW Williams Formula 1 cars.

  • Technical documentation and workshop manuals
  • CAD work (Siemens NX, Fusion 360) and 3D scanning
  • Parts identification and sourcing
  • Engineering tool development in MATLAB
