Join BLP Digital — The #1 Solution for ERP Automation
BLP Digital is redefining ERP automation with agentic AI. Spun out of ETH Zurich and HSG, we build AI agents that automate finance, procurement, logistics, sales, and more for some of the world's largest enterprises. We solve real enterprise problems with cutting-edge technology and a strong sense of ownership.
Our solution is live in 40+ countries, used by 20,000+ daily active users, and automates 70,000+ processes every day, including for Fortune 500 companies. As one of Switzerland's fastest-growing SaaS scaleups, our success stems from deep expertise in technology and business processes, delivering a product with outstanding product-market fit, proven by a growing global customer base.
We've recently welcomed Goldman Sachs Alternatives as a growth investor, and we're now expanding into the UK with the launch of our London office. We are just getting started. Ready to build the future? Join BLP Digital today.
We are seeking a Senior Backend Engineer with deep, hands-on expertise in the Ballerina programming language to design and operate the integration backbone that connects our agentic AI platform to enterprise ERP systems (SAP, Oracle, Microsoft Dynamics, and others). Ballerina is the core integration language in our backend stack, and you will own services that run in production for Fortune 500 customers, where correctness, reliability, and observability are non-negotiable. We need an engineer who already thinks in Ballerina's network-aware abstractions, structural typing, and service primitives, and who can raise the bar of our integration architecture from day one.
Design, implement, and operate production-grade integration services in Ballerina, connecting our AI agents to ERP, finance, and procurement systems
Model complex enterprise data flows using Ballerina's structural typing, native JSON/XML handling, and service constructs
Build resilient, concurrent services using Ballerina's language support for asynchronous workflows and network interactions
Operate Ballerina services in containerized and orchestrated environments, leveraging Ballerina's Docker and Kubernetes integrations
Define and enforce engineering standards for Ballerina code: idiomatic patterns, testing strategies, error handling, and observability
Collaborate with platform, AI, and product engineers to translate enterprise integration requirements into maintainable Ballerina services
Contribute to architectural decisions on language choice, integration patterns, and platform evolution
Mentor engineers joining the Ballerina codebase and rigorously review their contributions
10+ years of professional backend engineering experience, with at least 1 year of production experience writing and operating Ballerina services
Deep working knowledge of the Ballerina language: services and listeners, structural and union types, error handling, workers and strands, async patterns, and the Ballerina module system
Experience building integrations with enterprise systems (SAP, Oracle, Microsoft Dynamics, REST/SOAP APIs, message brokers, or comparable)
Strong command of functional programming concepts (immutability, pure functions, algebraic types) and ability to apply them in Ballerina or comparable languages
Hands-on experience with Kubernetes and Docker in production environments
Solid understanding of distributed systems, concurrency, and network protocols (HTTP, gRPC, messaging)
Proven ability to design and develop domain-specific languages (DSLs) tailored to complex business needs
Expertise in databases, including efficient raw SQL query writing and scalable system design
High degree of precision, thoroughness, and attention to detail
Ability to reason carefully about complex systems and edge cases
Contributions to the Ballerina open-source ecosystem (ballerina-lang, Ballerina Central packages, or related projects)
Experience with ERP integration patterns (SAP S/4HANA, RFC, BAPI, IDoc, OData, Oracle Fusion, MS Dynamics)
Background in financial services, audit, or enterprise back-office automation
Experience with other functional languages (F#, Haskell, OCaml, Scala)
Familiarity with CI/CD pipelines, observability tooling (OpenTelemetry, Prometheus, Grafana), and incident response
Exposure to compliance-driven environments (SOC 2, ISO 27001, financial regulations)
We value engineers who treat integration code as a first-class engineering discipline, not glue. We look for people who choose Ballerina deliberately, understand why network-aware language design matters, and care about building services that are understandable, maintainable, and reliable for years to come.
Join BLP Digital AG as a Senior Backend Engineer (Ballerina)! Shape the future of AI and enterprise systems by designing and operating mission-critical integrations for top global clients.
