Company: monday.com
Apply for the Senior Campaigns Software Engineer – AI-Driven CRM (London)
Location: London
Job Description:

At monday.com, we help teams get more work done. We are the best AI work platform that empowers teams to automate, build, and scale their impact end‑to‑end with tools that actually execute the work for you. With over $1B in ARR, 250,000+ customers, and a global team, we’re serious about building a product people love to use and giving our employees the same ownership and flexibility to shape the way the world works.

We care about the impact you make, not the hours you clock, so we encourage initiative, ownership, and fresh thinking. We back our people with flexible work, wellness and mental health support, and a work environment built on collaboration.

We’re currently expanding our engineering teams in London and looking for experienced Tech Leads. This is an individual contributor role with technical leadership scope, it’s not a people management position.

You’ll drive the development of infrastructure features that shape our product’s future from UI to database. This is a hybrid role based in our London office in Fitzrovia, with 3 days per week on site.

About the team

Our CRM group is expanding into a new, strategic area of the platform. This is a rare opportunity to help build it from the ground up. You’ll be involved in shaping direction, validating ideas quickly, and driving them through to implementation, not just executing on a defined roadmap. It’s a high‑ownership, high‑decision‑making environment where you work closely with Product and GTM teams to understand customer needs and translate them into something real. AI is central to the vision, and we’re designing for where the space is heading over the next few years, not just optimizing for today. It’s a collaborative, full‑stack team (Node.js and React) based in London, and we thrive on people who bring strong product sense, a bias for action, and a founding‑engineer mindset that’s comfortable with ambiguity and energized by new challenges.

What you will do

  • Play a key role in shaping our product architecture and engineering excellence.
  • Evolve our architecture and engineering practices to support the growing scale of users, features, and data.
  • Work alongside experienced developers with cutting‑edge technologies.
  • Collaborate closely with Product and Design teams, taking full ownership from conception to post‑deployment in a fast‑paced, dynamic environment.
  • Use the tech stack: React.js, Redux, Node.js, Ruby on Rails, AWS, Elasticsearch, Redis, MySQL.

Requirements

  • 6+ years of experience as a Software Engineer.
  • Strong technical expertise with a proven track record of building products that people love and use.
  • Full‑stack development experience, primarily focused on back‑end products.
  • Deep product understanding and a passion for creating software that delivers an exceptional user experience.
  • Strong team player with excellent communication skills and empathy.
  • Commitment to quality and simplicity in engineering and product development.
  • Domain experience in adtech or martech is extremely beneficial.
  • Product development experience is hugely advantageous.

What monday.com can offer you

  • Opportunity to join a well‑funded, publicly listed company with big ambitions and strong growth potential.
  • Competitive base salary, bonus, and RSUs.
  • Private healthcare insurance, critical illness and life insurance coverage.
  • Pension contributions matched up to 7%.
  • ClassPass membership.
  • Buffet breakfast and lunch provided at the office, Monday to Thursday.
  • A fully dedicated learning and development team with opportunities to hone and gain new skills.
  • Fun team events, socials and off‑sites.
  • Amazing company culture that values transparency and collaboration while never forgetting to have fun while we work.
  • Named “Best Place to Work” in the UK.
  • A global, dynamic and passionate environment with employees in Tel Aviv, New York, San Francisco, Miami, Chicago, Denver, London, Warsaw, Sydney, São Paulo and more.
