Job summary

Camunda in a remote-first setup is hiring a Senior Software Engineer for our Data Streaming team to build a foundational architecture that enables scalable access to process data. You will help move streaming workloads off the live engine and design a durable, decoupled data path.

You will partner with Product, Data Layer, and SRE to shape the streaming architecture, implement with systems like Kafka, and contribute meaningfully in a small, high-ownership team.

Qualifications

• 7+ years of backend engineering experience in Java, focused on distributed/data-intensive systems.
• Experience building/operating analytical serving layers on table formats (Iceberg/Delta Lake) or stateful stream-processing frameworks (Flink, Kafka Streams).
• Experience with object storage systems (S3/GCS/Azure) and reliable upload/commit protocols.
• Strong grounding in correctness and consistency in data-intensive systems.
• Proven track record leading medium-to-large engineering initiatives end-to-end.
• Strong communication/collaboration in a remote-first environment.

Responsibilities

• Help rebuild Camunda's analytics product to consume and serve process data at scale.

Job description

Camunda is the enterprise platform for agentic orchestration, enabling organizations to coordinate AI agents, people, and systems across complex, end-to-end business processes. With built-in governance, auditability, and human oversight, Camunda gives enterprises the control they need to move AI from pilots to production — safely and at scale. Trusted by over 700 organizations worldwide, including 9 of top 10 US banks, Camunda helps enterprises boost operational efficiency, accelerate time-to-value, and deliver better customer experiences.

Fully remote and global, we are in the middle of something bigger: transforming into an AI-first organisation, built on our own platform. We use Agentic AI to automate, orchestrate intelligent processes, and elevate human contribution across every team.

Named GP Bullhound’s Top 100 Next Unicorn list, 2025 Great Place to Work certified. Visionary in 2025 Gartner® Magic Quadrant™ for Business Orchestration and Automation Technologies. ranked 3rd in Flexa's 2026 Most Flexible Companies, We’re growing fast and looking for top talent to join our team.

About The Role

As a Senior Software Engineer on Camunda's new Data Streaming team, you'll help build a foundational new piece of architecture that changes how customers and internal products access process data. Today, customers have no first-class way to stream their own process data out of Camunda, and Camunda's own analytics product is bottlenecked by querying the same storage the live engine depends on. You'll be part of a greenfield team rebuilding how process data is consumed and served at scale, built on top of a durable, continuously-written streaming layer that decouples data consumption from the live engine. You'll be part of a small team from day one, with real room to shape both the architecture and the team's scope as it matures.

At Camunda, we approach engineering in a holistic manner. As such, you will form strong partnerships with product management, the Data Layer and Distributed Systems teams, QA, and support, and work closely with your peers to not only deliver but directly influence how our data streaming architecture evolves to meet our customers' needs.

What You Will Do

• 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.

Must Haves

What You Will Bring to the Role

• 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.

Nice To Haves

• Experience with Kafka or a similar streaming/event‑log system
• Experience with embedded state stores (RocksDB or similar) for projection/checkpointing workloads.
• Experience with stream processing frameworks (e.g. Apache Flink), particularly stateful processing with local state backends and checkpointing.
• Familiarity with object-storage-native streaming architectures (e.g. systems like WarpStream) is a plus, even without direct hands‑on experience.
