Remote (US/UK/SG)
Dear Hiring Committee,
I am excited to submit my application for the Senior Software Engineer, Backend – Distributed Systems position on Camunda’s Distributed Systems team. With 7+ years of experience designing, building, and operating high‑throughput, highly‑available backend services—most recently leading a multi‑region, Raft‑based streaming platform at [Your Current/Previous Company]—I am confident I can help Camunda continue to deliver enterprise‑grade, mission‑critical orchestration capabilities to its global customers.
Why Camunda & This Role
Camunda’s vision of “trusted AI agents for business‑critical processes” resonates deeply with my passion for building robust, observable, and developer‑friendly distributed systems that empower both people and machines. The opportunity to work on cutting‑edge components such as the multi‑Raft implementation, SWIM‑based cluster membership, and high‑performance I/O pipelines aligns perfectly with the challenges I have tackled throughout my career.
Relevant Experience & Impact
| Experience | Highlights |
|---|---|
| Lead Engineer – Distributed Streaming Platform – [Current/Previous Company] (2021‑Present) | • Designed and shipped a Raft‑based log replication service handling >10 M events/sec with sub‑10 ms tail latency. • Implemented online backup/restore APIs and multi‑region failover, reducing RTO from 30 min to < 5 min. • Built operator tooling (CLI, Grafana dashboards, automated health checks) that cut mean‑time‑to‑detect incidents by 40 %. |
| Senior Backend Engineer – [Company] (2017‑2021) | • Developed a high‑concurrency, disk‑I/O‑optimized ingestion pipeline using Java NIO, zero‑copy, and adaptive batching, achieving 3× throughput over legacy code. • Championed observability: integrated OpenTelemetry tracing, Prometheus metrics, and structured logging, enabling L3 support to resolve performance regressions within minutes. • Mentored a team of 5 engineers, driving agile delivery of two major releases per quarter. |
| Open‑Source Contributor – [Project] (2019‑2022) | • Contributed Raft and CRDT implementations to a popular open‑source workflow engine, gaining deep familiarity with consensus algorithms and state‑machine replication. |
How I’ll Contribute at Camunda
- Design & Build Scalable Services – Leverage my expertise in low‑level network & disk I/O, back‑pressure handling, and concurrency to evolve Camunda’s streaming platform for even higher durability and horizontal scalability.
- Drive End‑to‑End Initiatives – Own medium‑to‑large engineering projects from product discovery through delivery, producing clear solution designs, realistic roadmaps, and measurable success criteria.
- Elevate Resilience & Disaster Recovery – Extend the online backup/restore API, improve multi‑region replication, and introduce automated chaos‑testing pipelines to strengthen Camunda’s SLAs.
- Empower Developers & Operators – Create intuitive CLI tools, rich observability dashboards, and self‑service diagnostics that reduce on‑call fatigue and accelerate incident resolution.
- Collaborate Across Functions – Partner with Product, Design, QA, SRE, and Support in a remote‑first environment, translating business goals into technical deliverables while fostering a culture of transparency and shared ownership.
Cultural Fit
Camunda’s commitment to inclusivity, flexibility, and continuous learning mirrors my own values. I have thrived in fully remote, globally distributed teams, consistently delivering high‑quality code while nurturing a supportive, collaborative atmosphere. I am eager to bring that same energy to Camunda’s “everyone is welcome” culture.
Thank you for considering my application. I look forward to the possibility of discussing how my background, technical expertise, and passion for distributed systems can help Camunda accelerate its mission of trusted AI‑driven automation.
Warm regards,
[Your Name]
Quick Checklist Before Sending
- Personalize the company‑specific details (e.g., mention the “Camunda Exporter” talk you watched).

- Attach an up‑to‑date resume that highlights the same projects and technologies listed above.
- Proofread for any typos or formatting inconsistencies.
Good luck with your application! If you’d like help polishing your résumé, preparing for technical interviews, or tailoring any other application material, just let me know.
Requirements
- 7+ years of professional experience as a software engineer, with a strong focus on backend systems and/or distributed systems.
- Proven experience leading medium‑to‑large engineering initiatives (roughly 3+ months), breaking down ambiguous problems, writing clear solution designs and project plans, coordinating with multiple teams, and driving predictable delivery.
- Hands‑on experience building and maintaining highly concurrent, data‑intensive software, with a deep understanding of low‑level network and disk I/O (for example, throughput, latency, backpressure, batching, and failure modes).
- Demonstrated ability to work autonomously and navigate ambiguity – you are comfortable taking on problems you haven’t solved before, breaking them down into concrete steps, and driving them to completion with minimal supervision.
- Strong communication and collaboration skills in a remote‑first environment: you tailor explanations to your audience, translate business requirements into actionable technical work with Product, and help teams reach clear, decisive outcomes with minimal churn.
Responsibilities
- Design, build, and maintain backend services for the distributed streaming platform that powers the foundation for Camunda 8’s orchestration capabilities, ensuring durability, high availability, and horizontal scalability.
- Lead medium‑to‑large engineering initiatives (3+ months) end‑to‑end: partner with Product to translate business problems into technical requirements, write solution designs, draft and maintain project plans, and drive timely, high‑quality delivery.
- Help mature our disaster recovery and resilience story, including implementing and evolving an online backup/restore API and contributing to improved multi‑region and multi‑tenant capabilities for our cloud offering.
- Design and implement developer and operator tooling that makes it easier to understand, troubleshoot, and safely operate a complex distributed system in production environments.
- Improve engineering effectiveness by collaborating with DevOps and other Core Application teams on CI, testing, and local development workflows to reduce PR time‑to‑merge and the overhead of working on multiple features in parallel.
- Participate in L3 support and on‑call rotations, partnering closely with Support and SRE to investigate and resolve complex, performance‑sensitive production issues, and feeding what you learn back into our product and platform.
