Pre-Sales Engineer

Full-time | Madrid | On-site

Complex technology. Demanding customers. Proposals that need to win.

We are looking for an experienced Pre-Sales Engineer who can understand complex customer needs, translate them into viable technical solutions, and build the proposals that articulate and defend those solutions.

At XRF, we develop technology for decision-making in critical environments, combining AI, XR, GIS, video, sensors and interoperability. We work on real-world projects across Defence, Emergency Response and Critical Infrastructure, where understanding technology, operations and customer needs is equally important.

This is a hands-on role. We are not looking for someone to lead a department, nor for someone who still needs to develop their Pre-Sales expertise. We are looking for someone who has already done this job and can take ownership from day one.

What we offer

XRF is at an exciting stage: we have a real product, active projects and customers, and we are growing while building many of the capabilities we will need for our next stage.

You will join while our Pre-Sales function is taking shape, giving you room to bring your expertise and take ownership of how we structure, document and present our solutions.

- Real ownership: you will take direct responsibility for relevant proposals and processes.
- Direct access: you will work closely with Sales, Product, Engineering, partners and customers, without unnecessary layers.
- Visibility: you will understand what we are trying to achieve, take part in the conversations and see the outcome of your work.




- Interesting problems: you will work on complex technologies and projects where there is rarely a standard answer.
- The right moment: you will join at a stage of growth where there is still plenty to build, and the people joining now can have a real influence on how we do it.

Your work does not end when a document is submitted. You will be part of building the solution we are selling and delivering.

What you’ll do

Your mission will be to turn customer needs into solid, executable and competitive technical proposals.

- Gather and translate technical and operational customer requirements.
- Design and structure solutions together with Product and Engineering.
- Prepare and write technical proposals, RFP/RFQ responses and tenders.
- Coordinate technical and documentation inputs from internal teams and partners.
- Prepare technical documentation for projects and programmes, including European programmes.
- Participate in technical meetings with customers, integrators and other stakeholders.
- Ensure consistency between what the customer needs, what we propose and what we can deliver.

This is not about mechanically responding to RFPs.



It is about building the technical case that makes a solution win.

What we’re looking for

- Solid experience in technical Pre-Sales or an equivalent role, working directly with customers and technical teams.
- Strong technical background, ideally with a degree in Telecommunications, Software, Industrial or Aerospace Engineering, or a similar technical field.
- Hands-on experience preparing and writing technical proposals, RFP/RFQ responses, tenders or complex technical documentation.
- Ability to take ownership of a proposal, from gathering requirements through to structuring the solution and coordinating the technical response.
- Experience understanding complex technology, system architectures and integrations.
- Experience in Defence, the public sector, critical infrastructure or similarly demanding technology environments.
- Excellent ability to structure, synthesise and communicate complex technical information in writing.
- Ability to work across Sales, Product and Engineering, bringing different inputs together into one coherent proposal.
- Fluent Spanish and English, with the ability to write technical documentation and present effectively in both languages.
- Based in Madrid or genuinely available to work on-site in Madrid.

We will particularly value experience in public procurement, Defence/NATO environments, EDF/Horizon or other European programmes, integrators/primes/consortia, as well as technologies such as C2, ISR, GIS, AI, simulation or tactical systems.
