Full Stack Software Engineer (Freelance) in London

Time commitment: Freelance project lasting around 3 to 5 months.

Reporting to: VP of Technology, Avishai Gurt.

About Paloma:

Paloma’s mission is to make children’s autism and ADHD assessments and care available on the NHS within 4 weeks of GP referral. We are making this possible by setting a new standard for high-quality autism and ADHD care, building great software & AI tools, and investing in clinicians’ learning & development.

Mark and Darshak founded Paloma due to their frustration that families are waiting 4-10 years for NHS children’s autism and ADHD assessments. This crisis in NHS children’s neurodevelopmental services has been highlighted by the Children’s Commissioner for England.

Since launching, we have:

• Grown a fantastic team of 120 people, of whom over 80 are clinicians supporting families through their assessment journey.
• To meet the needs of families, we are recruiting >100 more people in the next 12 months.
• Raised £5m pre-seed funding from leading healthcare investors (Triple Point Ventures and Heal Capital), helping us to invest in our technology and our team.
• Achieved financial sustainability.

How is Paloma Health different from other Neurodevelopmental providers?

• Our clinical quality: We are clinically led, Care Quality Commission (CQC)-registered, measure our outcomes, and continuously improve our pathway for families and clinicians.
• Our internal product & engineering team, who build fantastic software to give families a fantastic consumer-like experience of healthcare and free our clinicians from documentation to focus on supporting families.
• Our strong culture: including transparency, a sense of community, and supporting staff career development.
• The experience of our founders, Dr Mark Jenkins & Darshak Shah, who have previously built tech-enabled NHS obesity and ophthalmology services.

The opportunity:

Do you want to finish every day knowing you directly improved the lives of children and families by speeding up access to NHS children’s autism and ADHD assessments? Would you like the freedom to work using the latest AI tools for software development? If yes, come join Paloma’s team of 7 software engineers and 3 product experts!

As a Fullstack Engineer, you will own specific workstreams to continuously improve the Paloma Portal, our AI-powered patient pathway and Electronic Patient Record (EPR) software.
