Software Engineering Events in London

This is the widest category on Brainberg, because software engineering itself spans a huge range of events: language user groups (Python, Rust, Go, TypeScript, Kotlin, Elixir, Ruby, Zig), framework communities (React, Svelte, Next.js, Vue, Laravel, Django, NixOS), backend architecture tracks, testing and QA tracks (ISTQB certification courses, mutation testing, test-automation workshops), refactoring and DDD circles, hackathons, and the long tail of "thoughtful engineering" meetups that don't fit neatly under any specific stack.

This page narrows the London calendar to Software Engineering events. It's a subset of United Kingdom's wider tech-event schedule, useful when you want something specific to go to in the city this month.

London has one of the largest single-city tech-event calendars in the world. Every major engineering discipline sustains multiple monthly meetups here (AI-applied, ML research, backend, frontend, cloud, DevOps, security, data), and every major international conference has a London edition or satellite. Engineering leadership is unusually strong: LeadDev London is effectively a pilgrimage event, and CTO Craft, staff-engineer communities, and product-management meetups (Mind The Product) run year-round.

Lessons from Leading Women Tech Entrepreneurs

London, 🇬🇧 United Kingdom

WiTT's annual discussion among women tech entrepreneurs

The November meeting of Women in Telecoms & Technology (WiTT) celebrates women entrepreneurs in tech with a panel discussion among leading women who have founded, grown, and in some cases sold businesses in the tech sector. Our women entrepreneurs event is timed to take place in the week before Global Entrepreneurship Week, which runs from 16-22 November 2026.

Audrey Mandela, WiTT Chair and co-founder of Multimap.com, will chair the panel.
Our speakers will be announced closer to the date of the event.

Our panel will discuss their views and experiences, including:

  • panelists' own challenges in starting and growing (and in some cases selling) their businesses;
  • best and worst decisions made while building their businesses;
  • whether panelists believe there are differences between male and female entrepreneurs, the types of businesses they start, their management styles, and their experiences of raising capital;
  • views on scaling up businesses started in the UK; and
  • advice for other women entrepreneurs.

We'll begin at 6:00pm with networking. The panel will run from 6:45 to 7:45, including Q&A. Drinks and canapes will be served after the panel finishes.

WiTT would like to thank Michelmores LLP for hosting.

Please email info@wittgroup.org if you have any questions. We look forward to seeing you on November 10th!
