Bring your experience to Europe's leading open source developer conference

OCX is built around people sharing what they know, what they are building, and what they have learned along the way. If you have an idea, experience, or lesson worth sharing, we would love to have you be part of the program.

Dates will be announced here and through the OCX and Eclipse Foundation community newsletters. In the meantime, explore the tracks and session formats below and start thinking about what you might like to share.

Your perspective belongs at OCX

Whether this would be your first conference talk or you have presented at OCX before, your experience and perspective can add something valuable to the program. We are looking for developers, maintainers, architects, researchers, engineering and business leaders, policymakers, open source contributors, and practitioners from across the open source and technology ecosystem.

Maybe you have solved a difficult technical problem, tried a new approach and learned something unexpected, put an emerging technology into practice, or are working through a challenge others are facing too. If you have something others could learn from, we want to hear from you.

What makes a strong proposal?

We’re not looking for polished pitches. We’re looking for useful ideas, genuine experience, and something others can learn from. First-time speakers are welcome (view our speaker agreement). 

Show us something real

Share what you have built, tested, researched, or put into practice. Real-world examples and demos help bring ideas to life.

Share what you’ve learned

Tell us what worked, what didn't, and what you learned along the way.

Know your audience

Be clear about who your session is for and what they will learn, understand, or be able to do afterward.

Give people something they can use

Leave attendees with ideas, knowledge, or approaches they can take back to their own work.

Keep it useful, not promotional 

OCX is vendor-neutral. Technologies, tools, and products can be part of the story, but your session should focus on sharing knowledge, not selling something. Promotional presentations and lead collection are not part of the program. 

Find the right track for your idea

OCX 2027 is organised around five tracks, but many of the most interesting ideas cross traditional boundaries. Choose the track that best reflects the main focus of your proposal. It does not have to fit perfectly.

Software-defined systems & mobility

01

Engineering an increasingly software-defined world

Software is reshaping vehicles, devices, machines, and connected systems. This track covers the architectures, platforms, and engineering practices behind next-generation software-defined vehicles, embedded and edge systems, robotics, autonomous systems, and other intelligent, connected products.

Modern software development

02

Rethinking how software gets built

How we design, build, and maintain software continues to evolve. This track covers AI-assisted and agentic development, programming languages and runtimes, cloud native, developer tools, DevOps, platform engineering, and the architectures and practices teams are using today.

Digital autonomy & technological sovereignty

03

Building for greater choice, control, and independence

Digital autonomy depends on the choices we make about architecture, infrastructure, data, standards, and technology dependencies. This track examines how open technologies can help organisations and governments build more adaptable and resilient systems while reducing critical dependencies.

Cybersecurity & regulatory compliance

04

From requirements to real-world readiness

Building secure software now means navigating both technical risks and regulatory requirements. This track covers secure development, software supply chain security, vulnerability management, SBOMs, open source compliance, and the practical impact of regulations such as the Cyber Resilience Act and AI Act.

Research & innovation

05

Where emerging ideas meet real-world applications

New technologies become useful when they move beyond the lab. This track brings together applied research, experimental technologies, and real-world engineering, with a focus on AI, software engineering, embedded and edge systems, open science, collaborative R&D, and moving research into production.

Not sure which track?

Choose the track that comes closest. The Program Committee may move proposals between tracks during the review process to help create the strongest overall program. 

What happens after you submit?

Here are the key dates for the OCX 2027 Call for Proposals and when you can expect to hear from us.

Call for Proposals opens

Start submitting proposals for OCX 2027.

Early submission deadline

Submit early for the opportunity to be considered for early program announcements and promotion.

Final submission deadline

The final day to submit your proposal for OCX 2027.

Speaker notifications

Everyone who submits a proposal will be notified of the outcome. Accepted speakers will also receive everything they need to start preparing for OCX 2027.

Already submitted? There is no need to register until you hear from us. Accepted speakers receive a complimentary conference pass.

How proposals are selected

Your proposal will be reviewed by members of the OCX Program Committee who understand the track, its technologies, and the people we hope to bring together. They'll consider four things:

  1. Clarity
    Can we quickly understand what the session is about, who it’s for, and what attendees will get from it?

  2. Relevance
    Does the topic matter to the audiences and communities coming to OCX?

  3. Originality
    Does it offer a useful perspective, experience, approach, or idea?

  4. Impact
    Will attendees leave with something valuable they can use, explore, or think differently about?

You can meet the people helping shape this year’s program on the program committee page.

What you receive as an OCX speaker

As an OCX speaker, you are part of the community that makes the program possible. We want you to get as much from the experience as the people who come to hear you speak.

Complimentary conference access

Enjoy the full OCX experience, with access to all five tracks throughout the conference.

An invitation to the speaker dinner

Meet and connect with fellow speakers at an informal dinner in Brussels before the conference.

Promotion through OCX channels

We will introduce you and your session to the OCX community through our communications channels.

A recording of your session

Your session will be published on the OCX YouTube channel, extending its reach beyond the conference.

Speakers are responsible for their own travel and accommodation. See the venue when planning your trip, and review the speaker agreement for the full terms, including consent to being recorded. All OCX participants agree to follow the Code of Conduct.
