- You will be directly involved in shaping and delivering critical features and system architectures, collaborating closely with senior leadership like the CTO and CEO
- There is no people management involved, just technical excellence and a relentless drive to deliver business-impacting solutions
- You will work across a range of technologies, adapt to changing requirements, and contribute to the evolution of our entire tech stack while maintaining a high standard of code quality
- Technical Leadership: Drive development using C#, ASP.NET Core, TypeScript, Vue.js, and other technologies. Own architectural decisions, contribute to product innovation, and ensure the highest levels of code quality through best practices and thorough reviews
- High-Impact Projects: Work directly with the CTO and CEO on company-wide, high-profile projects that have immediate business impact. Dive deep into emergency-like situations where your technical expertise is crucial for fast decision-making and delivery

Our take
In the landscape of business operations, the creation and communication of intricate diagrams pose a significant challenge. Traditional tools often fall short in terms of speed and aesthetics, making it time-consuming to produce visually impactful representations of deals, business flows, corporate structures, and more. Businesses face the need for a solution that not only accelerates the diagramming process but also enhances the visual appeal and clarity of these representations to align with modern standards of communication.
Enter Jigsaw, a solution addressing the shortcomings of traditional diagramming tools. Jigsaw is revamping the creation, manipulation, and presentation of business diagrams, offering an experience characterised by speed, aesthetics, and data accessibility. With the ability to build diagrams up to 40 times faster than conventional products, Jigsaw enables users to design complex graphics, turning them into live presentations or collaboration tools.
Moreover, Jigsaw serves as a centralised hub for all diagram-related information, allowing users to easily track, search, and modify data points associated with their diagrams, providing a solution to the challenges posed by traditional diagramming tools.

Diversity, Equity & Inclusion at Jigsaw
Catherine Alani (Chief People Officer)
- We recognise that a diverse team encourages the right conversations and challenges how our products work and who they work for. By creating an inclusive culture where people from different backgrounds and experiences can thrive, we are all better equipped to design and deliver solutions that meet the needs of a wider range of users.
- We want our hiring processes to be fair, transparent and accessible to the widest range of people. We never want people to be put off applying because they don't meet 100% of the listed criteria, and we never want someone to be deterred if they might need us to make a small change to the process so they can showcase their capabilities to the fullest.
- We appreciate that asking for accommodations during the interview process is daunting, and requires vulnerability when you don't know us yet. You do not need to tell us why you are requesting accommodations. Please email your recruiter to discuss and arrange accommodations. For example, this could be anything from audio transcription compatible video conferencing to an interview time that fits around childcare.
