It's ownership, impact, and the chance to change global payments forever.Join us in building Payments for the Next Billion.🙌 Your MissionWe are refactoring the warehouse for agents and cutting its cost.Analysts, operators, executives, and agents depend on the warehouse. The same question has to return one answer.As Senior Analytics Engineer, you own the transformation layer in dbt and Snowflake. You make it dependable: well modelled, tested, documented, and clear enough that a person or an agent can trust an answer. You are the data-engineering bar for the team, and you work alongside our other analytics engineer.You get up to speed on the stack we have, then help build the post-AI data stack: artifacts an agent can read, tools an agent can operate, context we own, and one reality the company can check.You set the quality standard by example. You are strong enough to shape the data stack over the long run.🎯 Your Responsibilities In This RoleOwn the modelling and transformation of your domains end to end in dbt and Snowflake, from the business question through to the governed model that answers itSet and defend modelling methodology alongside our existing Analytics Engineer, grain, dimensional patterns, and where the exceptions genuinely earn their placeMake your models agent-ready: semantically rich, consistently named, described in business terms, and safe for something to query without a person checking the outputOwn streaming and near-real-time pipelines (Kafka or similar) alongside batch transformation, keeping real-time flows reliable and cost-efficient before they become a bottleneckEstablish and enforce coding and agentic-coding standards, systematic testing and documentation as CI-enforced defaultsOptimise warehouse performance and cost, finding and fixing the query patterns and materialisation choices driving unnecessary spendDeploy and supervise autonomous agents against our data stack, and hold our data infrastructure to proper engineering standards: monitored, wired to incident.io and PagerDuty, with escalations, SLAs and documented processesSupport and mentor analysts on analytics-engineering practice, raising the engineering standard across the team🔥 Must-have requirementsThree or more years of production dbt. You can defend a modelling methodology. Kimball sits inside that defence: grain, facts, dimensions, and where a wide table is the wrong choiceA semantic layer you have used in production. You can explain metrics, dimensions, grain, and joins, and how an agent reads themStreaming and warehouse scale. You have owned CDC or another stream, incremental transforms, and a freshness choice with a cost. You can say when a batch model is the wrong place for a high-frequency number, and what sits beside the warehouse: a stream, a low-latency table, or a semantic APISnowflake or Databricks. You have worked on cost and scale: incremental versus full refresh, clustering, and a lag target a consumer needsOrchestration. You have scheduled, monitored, and repaired a pipeline in Airflow, Dagster, or an equivalentCI/CD and deployment management. You have run a project where a pull request builds the changed models and their downstream dependencies against production state, writes them to an isolated schema or clone, and promotes that same selection after merge. You can describe the path from a developer environment through CI into production, how a bad deploy is stopped or rolled back, and the signal that a deploy succeededThree or more years of production Python. You have shipped Python in a pipeline: transforms and checks that run without you. A take-home test, or a notebook, is not this requirementYou are passionate about building with agents and for agents. Serving agents data at scale is a problem you want. You have used frontier tooling to automate a traditional analytics workload, such as a recurring model change, a reconciliation, or a report. You can show the outcome in time or volume. You can explain how that system is observed, how it is governed, and how it scales past one person on a laptop💪 Nice to have requirementsAn ontology, or a business entity model, on top of a semantic layerA distributed engine such as Spark or Trino, used on data that did not fit a single warehouse queryFintech, payments, or another regulated environment✅ Success in the role looks like3-Month MetricsYou own the transformation layer and can name the models people do not trust, the numbers that disagree, and the queries that cost moneyA change to a live model is agreed and visible before it landsA teammate can follow your reasoning without a long private explanationYou have one automation a teammate can run, with a before and after in time or volume6-Month MetricsThe team uses the automation you taught them, and you can show the hours or the volume it changed➡️ Interview ProcessBefore you apply, take a look at our Extra Preparation guide, covering our engineering philosophy, tech stack, and what to expect at each interview stage.You will need to first submit your application through our ATS Workable. There is no need to submit a Cover Letter.If successful you will be selected for our interview process, which has the following stages:[30mins] Interview with the Talent Team We want to get to know you and follow up on your experience and motivations.
