Full job description
ABOUT US 👇🏼 lemlist is the sales engagement platform that gives sales teams the unfair advantage they deserve. Bootstrapped since day one, we’ve grown from 0 to $57M ARR in 8 years, without raising a single dollar. Today, we’re a profitable B2B SaaS company, trusted by 40,000+ sales teams worldwide to book more meetings and close more deals. We’re looking for a Data engineer to join our team. You will help design, build and improve scalable data platform to provide data solution to our product. YOUR MAIN MISSION WILL BE:
- Work collaboratively with the product and business teams to build scalable and agile solutions.
- Define our technical standards and take an active part in the structuring data platform architecture decisions and data platform deployment based on data strategic product roadmap
- Develop, deploy, and manage highly efficient data platform and automated data pipelines using cloud-based and on-premise technologies.
- Design, maintain, and enhance key data product feature to ensure they are high-quality, certified, and easily accessible/integrable by enterprise users, components, and systems.
- Analyze and develop data operations and pipelines in line with enterprise guidelines and best practices (e.g., data quality processes, governance, and deep catalog/glossary curation).
- Continuously adapt to evolving requirements by maintaining and improving existing data pipelines integrating new features and change requests using an agile approach.
- Ensure data quality, lineage, versioning, and observability across the whole stack.
- Support CI/CD and release processes KEY RESULTS Within 3 months, you will have/be:
- Successfully onboarded and integrated into the team.
- Onboarded our existing data platform end to end: sources, ingestion jobs, warehouse models, orchestration, BI layer, and who consumes what.
- Delivered a written audit of the current stack — what works, what's fragile, what's redundant, what's undocumented — with a severity ranking and estimated cost of each gap (reliability, cloud spend, engineering time, business risk).
- Shipped at least one visible quick win: a broken or unreliable pipeline fixed, a cost anomaly resolved, or a critical dataset made trustworthy.
- Turned the audit into an agreed technical roadmap: proposed target architecture, tech choices (warehouse, streaming, orchestration, transformation), and a migration path with trade-offs made explicit and validated with Product, Data and the C-suite.
- Improved our data engineering standards: repo structure, Git workflow, CI/CD for data, environments, code review, and deployment process. New pipelines follow them without needing to be told. Within 12 months, you will have:
- Participated actively in the improvement of our data platform in order to scale with data volume and product growth without recurring firefighting, and cost per pipeline is understood and controlled.
- Cut incident volume and time-to-detect on critical datasets to a level where business teams trust the data by default.
- Put observability in place: freshness, volume and schema checks with real alerting on our critical datasets, plus documented SLAs and clear ownership.
- Unlocked new use cases the business couldn't previously ask for: proposed and shipped platform capabilities that opened up work in product analytics, in-product data features, or ML/AI enablement for the Data Scientist
- Become an additional reference on our data architecture — the person the C-suite (CEO, CPO, CMO, Head of Sales) and Product consult before committing to decisions with a data dependency. WHAT’S IN IT FOR YOU?
- Work in a profitable, bootstrapped, and high-growth company that doesn’t rely on external funding to live.
- Work on high-impact projects with highly skilled data profiles composed of a Senior Analytics Eng, a Senior Data Scientist and a Senior Data Engineer that directly drive business decisions
- Collaborate directly with the C-suite on strategic topics
- Work with a team obsessed with speed, growth, and impact. PREFERRED EXPERIENCE Must have:

- Extensive expertise in data preparation, integration, modelling, and governance processes.
- Proven experience in designing and managing end-to-end production ready solutions.

- Familiarity with DataOps know-how: Git, Docker, CI/CD practices (Jenkins) and deployment workflows in a data engineering environment
- Experience in ensuring data quality, consistency and performance across data platforms, while applying data governance principles.
- Strong analytical mindset, with the ability to solve complex data challenges and continuously improve data solutions.
