Job summary

Camunda, a global remote-friendly tech company, is seeking a Senior Software Engineer for the Data Streaming team. You will help build the foundational architecture to stream process data at scale, decoupling it from the live engine and enabling customers to access data with low latency.

You will collaborate with Product, Data Layer, and SRE, shaping the streaming stack and influencing product direction while delivering robust, scalable infrastructure in a remote-first environment.

Qualifications

• 7+ years of experience as a backend engineer, in Java, with a strong focus on distributed or data-intensive systems.
• Hands-on experience building or operating an analytical serving layer over a table format such as Apache Iceberg or Delta Lake - including experience with an embedded/lightweight query engine (e.g. DuckDB, or similar), or a stateful stream-processing framework (e.g. Flink, Kafka Streams).
• A track record of working with object storage systems (S3/GCS/Azure or similar) and building reliable, idempotent upload/commit protocols against them.
• Solid grounding in the reasoning behind correctness and consistency in data-intensive systems (e.g. concurrent writes, atomicity, idempotency).
• A demonstrated track record of driving a technical initiative through genuine ambiguity in a still-being-designed system, not just extending an established one.
• Proven experience leading medium-to-large engineering initiatives (3+ months) end-to-end, from solution design, project planning, and coordinating across teams, right through to driving predictable delivery.
• Strong communication and collaboration skills in a remote-first environment: you translate requirements into actionable technical work with Product, and give and receive clear, direct feedback in code review.

Responsibilities

• Help rebuild how Camunda's analytics product consumes and serves process data at scale, moving it off the engine's critical path entirely.
• Design and build the core streaming infrastructure that decouples process data access from the live execution engine, backed by durable, object storage.
• Build customer-facing data streaming capabilities, including a supported way to integrate with systems like Kafka, so customers can reliably get their process data into their own tools.
• Make foundational architecture decisions as part of a small, high-ownership team, including how the system guarantees consistency and durability across a distributed streaming pipeline.
• Participate in L3 support and on-call rotations, partnering with Support and SRE to investigate data layer production issues, and feeding what you learn back into the product.
