Behind the scenes, a distributed log service is making it all possible — and you'd be building it. The AlfBus Journal organization builds foundational distributed systems that power the largest AWS services. We specialize in high-performance, strongly consistent data systems that operate at scale. Our systems process over 4 million writes per second today and are growing fast. When we ship, the blast radius is AWS itself. We have a multi-year roadmap packed with hard, unsolved problems: building next-generation data export services, driving large-scale migrations that will reshape Amazon's storage infrastructure, and pushing the boundaries of durability, availability, and performance in distributed log systems. This isn't incremental work — it's foundational. As an SDE-II, you'll own systems end-to-end: from requirements and design through implementation, deployment, and production support. You'll work alongside multiple Senior and Principal Engineers on a tight-knit team of 11 that values pairing, co-ownership, and direct collaboration. You'll also mentor junior engineers and help raise the team's technical bar through design reviews and engineering best practices. If you want to go deep on distributed systems and database internals — not just use them, but build the ones that AWS depends on — this is the role. ### Key job responsibilities - Design and build highly available, low-latency distributed log and database systems that process millions of writes per second for AWS's most critical services. - Own end-to-end delivery of software projects — from requirements through design, implementation, deployment, and production support. - Drive improvements to security, reliability, durability, and performance across multiple foundational services. - Lead and contribute to multi-year, cross-team migration and integration efforts with high-profile partner teams. - Mentor junior engineers through code reviews, design discussions, and pairing sessions. - Establish and evolve engineering best practices and operational processes for the team. ### A day in the life AlfBus Journal engineers are constantly challenged to think of unique and innovative solutions. The quality bar is high. As an engineer here, you will work on the engineering problems in distributed systems at a massive scale and on multiple dimensions. You will exercise your intellectual curiosity, work with motivated teams of sharp individuals, and get guidance from senior and principal engineers. This is a hands-on position in which you will own everything from end to end: requirements gathering, designs, design reviews, implementations, code reviews, incremental feature launches, operations, mentoring, and the driving of continuous improvement. ## At a glance - Posted by the employer: Oct 15, 2026 - First seen by OpenNash: Oct 18, 2026 - Last checked: Oct 18, 2026 - Listed for: 3 days - Location: US, WA, Seattle[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10580330/software-development-engineer-alfbus-journal) ## More jobs at Amazon ### [AWS Software Development Manager, Elastic Load Balancing](https://jobs.opennash.com/companies/amazon/jobs/8bc81eb90a02a81cc9b1/) US, WA, Seattle ### [Applied Science Manager, Computer Vision, Perception Science, Prime Air Vehicle Software](https://jobs.opennash.com/companies/amazon/jobs/f8f3afcff56816849d13/) US, WA, Seattle ### [Developer Experience Engineer, AWS Developer Experience](https://jobs.opennash.com/companies/amazon/jobs/fbd46cd6cad9f0b7a4b1/) US, WA, Seattle ### [Developer Marketing Manager, Developer Marketing](https://jobs.opennash.com/companies/amazon/jobs/d8c4520c33f205cd0159/) US, WA, Seattle ### [Director of Software Development](https://jobs.opennash.com/companies/amazon/jobs/cff67c726a21a2a83042/) US, WA, Seattle ## Similar jobs at other companies ### [Software Development Engineer](https://jobs.opennash.com/companies/fortinet/jobs/28951e39aa65fab8d748/) Fortinet · Sunnyvale, CA, United States ### [Software Development Engineer (GUI)](https://jobs.opennash.com/companies/fortinet/jobs/bb39f255ec65bd5058b8/) Fortinet · Sunnyvale, CA, United States ### [Software Development Engineer II](https://jobs.opennash.com/companies/optimum/jobs/bdef493135bced9dff7b/) Optimum · Bethpage, NY, US ### [Software Development Engineer III](https://jobs.opennash.com/companies/optimum/jobs/3fea6604c9aa98bcc956/) Optimum · Bethpage, NY, US ### [Senior Embedded Software Development Engineer](https://jobs.opennash.com/companies/microsoft/jobs/47f921f9ea9b6ae753e9/) Microsoft · United States, Washington, Redmond [Jobs in Seattle, WA](/locations/us/wa/seattle/)[Jobs in Washington](/locations/us-wa/)[Software Engineering jobs](/functions/software-engineering/) OpenNash lists jobs from employers’ own careers sites and does not handle applications.
