Technology Lead - Salesforce Marketing Cloud

monday.com

<div>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&rsquo;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 are scaling our engineering teams in London and we are looking for an experienced Tech Lead to join the team building and owning the infrastructure behind mondayDB - our in-house distributed database powering every board, dashboard, and workflow on the platform.
You will join the mondayDB group within our Data organization - the team that built monday.com&rsquo;s own database from the ground up to handle scale, performance, resiliency, and data integrity that off-the-shelf solutions couldn&rsquo;t. As an Infrastructure Tech Lead, you&rsquo;ll own the systems that keep mondayDB fast, available, and ready for the next order of magnitude.
Explore the future of monday with mondayDB.
Dive deeper into the architecture of mondayDB 1.0.
Our latest mondayDB 3.0 architecture
Check out our Engineering Blog &mdash; https://engineering.monday.com/
Please note this is a hybrid position of 3 days/week in our London office (Fitzrovia).<h2 class="jobSectionHeader">
About the role</h2>
We built mondayDB ourselves since nothing off the shelf could power 250,000+ customers at the scale and speed monday.com needs. Now that monday.com is rebuilding around AI agents working alongside humans, every agent action lands on mondayDB and the next order of magnitude in scale, latency, trust and reliability is the foundation the agentic platform runs on. Some of the group challenges:<ul><li>
Four 9s of availability across the services we own.</li><li>
Aggregating data from 5,000 boards in under 5 seconds.</li><li>
Supporting up to 10M items per board with p99 load times under 4 seconds.</li><li>
Aggregating 50M items per dashboard.</li><li>
Serving 100K+ requests per second.</li><li>
Enabling large data mutation in a reliable way</li><li>
Importing and exporting data at scale</li></ul><h2 class="jobSectionHeader">
What you&rsquo;ll do:</h2><ul><li>
Own mondayDB&rsquo;s infrastructure end-to-end. Tier-1 services on AWS, our Temporal.io cluster, Cassandra, PostgreSQL, DynamoDB, DuckDB, Node.js and Go microservices on Kubernetes - architect, build, evolve, operate.</li><li>
Drive the roadmap. Identify the bottlenecks, frame the bets, push the work forward. Tech Leads set technical direction here, not just execute it.</li><li>
Push the limits of scale and reliability. Hold four 9s while scaling to billions of items, 100K+ RPS, and dashboards aggregating 50M items in seconds.</li><li>
Build the orchestration layer. Design the Temporal-based workflows that move data through mondayDB - ingestion, indexing, aggregation, recovery.</li><li>
Get the best out of every datastore. Tune and operate the right tool for each access pattern - DynamoDB, Cassandra, DuckDB, and the glue between them.</li><li>
Own production. On-call for what you build. Tier-1 ownership means being on the hook and trusted to build systems that almost never need you.</li><li>
Raise the bar. Mentor engineers, lead design reviews, set the patterns the whole group builds on.</li></ul>
Note: Prior experience with our exact stack is not required; we welcome people willing to learn.<h2 class="jobSectionHeader">
Requirements:</h2><ul><li>
6+ years building and operating distributed, large-scale backend systems.</li><li>
Deep expertise in distributed systems - storage, concurrency, consistency, performance, failure modes.</li><li>
Hands-on production experience on a major cloud (AWS preferred) and Kubernetes.</li><li>
Strong working knowledge of at least one of DynamoDB, Cassandra, DuckDB, or comparable distributed datastores and a clear sense of when to reach for which.</li><li>
Track record of running tier-1 services and meeting tight SLOs.</li><li>
Comfort with workflow orchestration (Temporal, Cadence, Airflow, Step Functions, or similar) and the trade-offs involved.</li><li>
A bias toward ownership: happy on-call for the systems you build, proud of making them boring to operate.</li><li>
Excellent communication, empathy, and a commitment to quality and simplicity.</li></ul>
What monday.com can offer you:<ul><li>
Opportunity to join a well-funded, publicly listed company with big ambitions and strong growth potential.</li><li>
Competitive base salary, bonus, and RSUs.</li><li>
Private healthcare insurance, critical illness, and life insurance coverage.</li><li>
Pension contributions matched up to 7%.</li><li>
ClassPass membership.</li><li>
Buffet breakfast and lunch provided at the office, Monday to Thursday.</li><li>
Fully dedicated learning and development team that provides opportunities for our employees to hone and gain new skills.</li><li>
Fun team events, socials and offsites.</li><li>
Amazing company culture that values transparency and collaboration while never forgetting to have fun while we work! We've been named &quot;Best Place to Work&quot; in the UK.</li><li>
A global, dynamic and passionate environment with employees in Tel Aviv, New York, San Francisco, Miami, Chicago, Denver, London, Warsaw, Sydney, S&atilde;o Paulo, and Tokyo.</li></ul></div>
