Junior Software Engineer (Data)

Who is Silverflow? At Silverflow, we’re redefining payments. As the world’s first cloud-native acquiring processor, we’re replacing decades-old infrastructure with a fast, scalable, global platform. Founded in 2019, we’re founder-led, venture-backed, and growing fast. With 80+ dynamic colleagues from 30 different cultures, we are on track to reach 120 people by 2027. Our platform empowers a diverse range of clients, from banks to ride sharing platforms, helping them streamline operations, enhance data insights, and deliver seamless, real-time payment experiences at scale. What you'll do The Software Engineer (Data) builds and operates Silverflow's data platform: the pipelines, datasets, and services that turn microservice event data into the reporting, analytics, and AI products the whole company relies on. In a regulated payments environment, this data underpins customer invoicing, transaction reconciliation, and fraud research, so accuracy, timeliness, and reliability matter as much as the features themselves. This is a software-first role. You'll spend more time writing, testing, deploying, and maintaining code and infrastructure than doing data science. We're looking for someone with 1–3 years of experience, ideally from a software-heavy environment, who wants to own systems end-to-end with support from a senior team. Key Responsibilities Build & maintain the data platform:• Design, develop and maintain ETL pipelines. • Write well-tested, readable, production-ready code and participate in code reviews. • Deploy and maintain data infrastructure as code (Terraform, CloudFormation). • Instrument data-quality and observability checks. • Support our AI tooling and automation platform - data agents, self-serve query access, and workflow automation. • Support engineering teams in selecting and implementing suitable technologies. • Support product and business teams with internal tooling and datasets. Who you are Must Have • 1–3 years of experience in a software engineering, data engineering, or similarly software-heavy role. • Proficiency in at least one programming language, ideally Python, TypeScript and/or Go (Rust/ Java / Scala also welcome). • Solid software fundamentals: testing, version control (git), debugging, and clean, maintainable code. • Working knowledge of SQL and a good grasp of data processing concepts (data quality, deep-diving to find root causes). • Familiarity with cloud infrastructure, ideally AWS. • Exposure to infrastructure as code (Terraform, CloudFormation) and CI/CD pipelines. • Understanding of APIs and system communication. • Strong communication skills, able to work with non-technical stakeholders and explain technical topics clearly. • Able to operate in a fast-paced, self-driven environment. Nice to Have • Experience with a data processing framework (Spark/PySpark, Pandas, or similar). • Experience with columnar/analytical databases or data formats (Clickhouse, Iceberg/Parquet) or BI tooling (QuickSight/Superset/Looker). • Experience with non-relational data stores (MongoDB, or GraphQL etc). • Interest or experience in AI/ML tooling, LLM applications, or workflow automation. • Prior work in regulated industry (payments, financial services). Why join us? • A fun and people-first culture: Be part of a diverse team representing 30+ nationalities. Enjoy a daily team lunch, regular padel tournaments, and memorable annual events like our Christmas Party, company birthday celebrations, and off-site trip.
