Would you like to make a difference for people with disabilities, while helping build a tech startup from the ground up?

TalkiTale is looking for a Technical Co-founder to join at the earliest stage and help build the company, product, and technology foundation.

Note: The role is initially 100% equity-based, with salary once funding and/or revenue are obtained. Part-time engagement is possible in the initial phase. For the right person, this is a true co-founder opportunity with a substantial, double-digit equity stake, depending on experience, commitment, timing, and agreed responsibilities.

About TalkiTale

TalkiTale is a Danish startup supported by the Innovation Fund Denmark through the Innofounder programme. We develop mobile applications that can help children and adults with limited or absent speech due to disabilities such as Down syndrome, autism and cerebral palsy. Our first products include a sign-recognition app designed to recognize both standard signs and users’ personal or approximate signs, as well as an educational game for learning signs.

The company is currently in an early but active product-building phase, where the product concepts and technology have been through early validation (including an early-access app in App Store), but significant refinement and development work remains.

About the role

As Technical Co-founder, you would help shape and build the core technology behind TalkiTale, and work closely with the founder on both product and engineering. You will help develop TalkiTale's products into robust applications ready for use by children and adults with disabilities as well as their caregivers.

This role is especially relevant for someone who enjoys solving genuinely difficult computational problems. You should be interested in algorithmic development and data modelling, but at the same time know how to turn research-level prototypes into a real product that can be used by real users: with robustness, performance, maintainability, user experience, and privacy and security in mind.

Responsibilities may include:

• Developing and implementing novel algorithms for dealing with complex and noisy data, where there is no off-the-shelf solution

• Turning research ideas into practical, testable, production-ready implementations

• Designing and maintaining the architecture of mobile and backend systems

• Defining the technical roadmap

• Defining the company's strategy and making business decisions together with the founder

• Making pragmatic engineering decisions in an early-stage startup environment

• Eventually helping hire and lead a technical team

  
  

What we are looking for

We are primarily looking for evidence that you can tackle difficult computational problems where no "off-the-shelf" solutions exist, as well as evidence that you can produce production-ready code.

Your educational background may be in computer science, mathematics, physics or a similar quantitative field, and your experience may be for example from research, industry, open-source work, or competitions.

You may be a strong fit if you:

• Enjoy solving hard computational problems

• Are genuinely motivated to build a company where social impact and long-term value are the main drivers.

• Have very strong analytical skills and a quantitative background where you are comfortable working with noisy real-world data

• Have significant coding experience

• Can build reliable software, not just prototypes

• Can work independently and take ownership

• Want to be a true co-founder, with both technical and company-building responsibility

• Can thrive with uncertainty and freedom

• Believe that trust, honesty, and strong working relationships are the foundation of successful collaboration

Relevant experience could include one or more of the following:

• Algorithms, data structures, optimization and probabilistic modelling

• Time-series analysis, signal processing, pattern recognition, computer vision

• Backend development, databases, infrastructure, or developer tooling

• Applied research that has been turned into usable software

• Experience building production-ready systems used by real people

What we offer

• The opportunity to make a real difference for people with communication disabilities

• The opportunity to build a tech company from the ground up together with a passionate founder

• Co-ownership through substantial (double-digit) equity, with the exact level depending on experience, commitment, timing and agreed responsibilities

• A planned path to salary as we pursue our next funding milestones

• Significant influence on the company’s strategy, product and the building of a team

• A flexible and meaningful working life, with respect for your free time and family life

• Office in Aarhus, with the possibility of working remotely
