Senior Software Engineer - Campaigns

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.

Please note this is a hybrid role based in our incredible 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 — and this is a rare opportunity to help build it from the ground up. The team is working on a product that doesn't fully exist yet, which means 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'll work closely with Product and GTM teams to deeply understand customer needs and translate them into something real. AI is central to the vision, not an afterthought — we're designing for where the space is heading over the next few years, not just optimising for today. We're 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 the kind of founding-engineer mindset that's comfortable with ambiguity and energised by it.

About the role:

You'll work with experienced and highly talented engineers who are passionate about what they do, using cutting-edge technologies in a data- and impact-driven environment. We foster a culture of transparency, full ownership, teamwork, and a no-ego policy.

Our engineering department consists of multiple groups, each responsible for a critical domain within the monday.com product. With over 400 engineers, we operate in cross-functional teams, collaboratively defining, improving, building, and delivering features.

What you will do:

• Play a key in shaping our product architecture and engineering excellence.

• Evolve our architecture and engineering practices to support the ever-growing scale of users, features, and data.

• Collaborate closely with Product and Design teams, taking full ownership and responsibility from conception to post-deployment in a fast-paced, dynamic environment.

• Tech stack: React.js, Redux, Node.js, Ruby on Rails, AWS, Elasticsearch, Redis, MySQL.

• Strong technical expertise with a proven track record of building products that people love and use daily.

• Full-stack development experience, with a primary focus on backend.

• 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.
