We're also supporting the AI/ML platform team with reliable, low-latency feature pipelines and model serving infrastructure.</p> <p>We're collaborative, pragmatic, and we value moving fast by fixing the right problems—not over-engineering, but building to last!</p> <p>&nbsp;</p> <p><strong>The team is made up of three functions:</strong></p> <p><strong>Data Platform Engineering:</strong> Building and scaling ELT pipelines, managing data infrastructure on GCP, and creating the foundation for analytics and ML feature stores. You'll be part of a small, high-performing team of platform engineers focused on reliability, scale, and developer velocity.</p> <p><strong>Analytics Engineering:</strong> Transform raw data into trusted models using DBT and SQL, powering self-serve analytics and business intelligence for stakeholders across the company.</p> <p><strong>Data &amp; Business Intelligence</strong>: Build dashboards, partner-facing reports, and insights that drive business decisions and revenue outcomes.</p> <p>&nbsp;</p> <p><strong>What you'll get to do in the role:</strong></p> <ul> <li>Design, build, and maintain resilient data pipelines that ingest data from Azure SQL, SaaS platforms, and event streams into BigQuery.</li> <li>Write Python code using DLT to define declarative, testable, version-controlled pipelines - no low-code tools, real engineering.</li> <li>Build and operate ML feature pipelines - low-latency, real-time data streams that feed ML models with accurate, fresh features.</li> <li>Own the operational health of systems you build - monitoring, alerting, error handling, and incident response. When the data pipeline goes down, merchant credit decisions and ML model predictions suffer.</li> <li>Collaborate with analytics engineers to understand data needs, validate schema design, and establish data quality standards that both analytics and ML rely on.</li> <li>Partner with the AI/ML platform team to design feature stores, streaming feature infrastructure, and model serving pipelines that power Liberis' decisioning engine.</li> <li>Identify and execute optimisation work - improving performance, reliability, and developer velocity without rearchitecting stable systems.</li> <li>Mentor junior engineers, helping them grow as engineers and supporting their career development.</li> <li>Participate in technical decisions about platform direction - infrastructure choices, tooling, architecture trade-offs.</li> <li>Work cross-functionally with product teams, analytics engineers, BI specialists, and the ML platform team to shape data requirements and platform capabilities.</li> </ul> <p>&nbsp;</p> <p><strong>What we think you'll need:</strong></p> <ul> <li>8+ years of professional software engineering experience, with at least 4-5 years in data engineering roles (building and operating data pipelines at scale).</li> <li>Hands-on experience building Modern Data Stack architectures - you understand the layers: ingestion, warehouse, transformation, orchestration, reverse ETL. You've worked with tools like DLT/Fivetran/Airbyte (ingestion), BigQuery/Snowflake/Redshift (warehouse), DBT (transformation), Airflow/similar (orchestration).</li> <li>Strong Python programming - you write clean, testable, maintainable code with solid error handling and logging.</li> <li>Fluent SQL - you can write complex queries, understand execution plans, and optimize for performance and cost.</li> <li>Experience with cloud data platforms - you've built data warehouses in BigQuery, Redshift, Snowflake, or similar; you understand distributed processing, partitioning, cost optimization, and data governance.</li> <li>Experience with infrastructure-as-code tools (Terraform, CloudFormation, Pulumi) or equivalent - you version control infrastructure and deploy it via CI/CD pipelines.</li> <li>Experience working in fast-moving environments where requirements evolve and you adapt quickly without losing sight of reliability.</li> <li>Understanding of DevOps principles - you think in terms of observability, resilience, incident response, and operational excellence. You can set up monitoring and alerting that actually matters.</li> </ul> <p>&nbsp;</p> <p><strong>Bonus points if you have:&nbsp;</strong></p> <ul> <li>Experience with DLT or similar declarative ELT frameworks; experience with Google Cloud Platform ecosystem (BigQuery, Cloud Run, Pub/Sub, Dataflow); experience with Kafka, Pub/Sub, or event streaming platforms; experience scaling data systems from 0 to 100M+ events/day; experience implementing data quality frameworks (Great Expectations, dbt tests, custom monitoring); background in fintech or high-stakes data reliability environments where data quality directly impacts revenue.</li> <li>Experience working with distributed, asynchronous teams across timezones; experience in India tech ecosystem or building in resource-constrained environments; experience migrating from legacy data infrastructure (Azure ADF, traditional ETL) to modern cloud-native stacks.</li> </ul> <p>&nbsp;</p> <div class="p-rich_text_section">Career development is really important to us here at Liberis, with progression opportunities for both individual contributors and people managers.
