Digital transformation stacks, built primarily on top of open source-centric frameworks, power almost 90% of all new software built today, including most of the megatrends in the industry, including AI, Deep Learning, Analytics, IoT, Blockchain, AR/VR, Cloud-native Apps, and Mobile.

In order to continue to bring unique value to our clients and the ecosystem in the era of digital transformation, Mark III Systems complemented our long-time team of systems engineers and architects by adding capabilities years ago around automation and code, in addition to data science and industry subject-matter experts. With how open source has exponentially expanded the number of combinations of software stacks, it's not enough now to just understand individual platforms and technologies, but it's also mandatory to understand how to harness and connect them together, often in a hybrid cloud or core-to-edge scenario, to consistently succeed in the marketplace.

Mark III Systems was recognized as a Partner of the Future in 2017 by IDC as part of their Partners of the Future series under the pillar of continuous innovation.


Software Development Engineer at Amazon (Seattle, WA)

Amazon Quantum Ledger Database, a next generation purpose built database technology was announced in Preview at re:Invent 2018 and is seeing tremendous interest from AWS customers! It is a foundational technology of Amazon's Blockchain strategy and a revolutionary OLTP database with scalable throughput. Join us during this formative period of the product and be a leader in shaping the future of Amazon QLDB as we drive towards General Availability.

Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log of all application data changes over time. It offers a SQL-like API, flexible document data model and full support for transactions. QLDB eliminates the need for organizations to build ledger-like functionality when their applications require audit-ability and verifiability, such as, when tracking the history of credits and debits in banking applications, verifying data lineage of an insurance claim, or tracing movement of an item in a supply chain network. QLDB is serverless and highly scalable, allowing customers to scale effortlessly to support the demands of their applications.

We are looking for software engineers who thrive on creative problem solving and enjoy the challenge of operating mission critical systems under extreme loads. An ideal candidate will be able to dive into complex database and distributed systems problems to invent simple and elegant solutions. You will design, implement and deliver cutting edge database software that powers QLDB and drives its high availability, reliability, scalability and performance guarantees. You will care deeply about customer experience and focus on building performant systems that offer idiomatic interfaces to customers. You will have high standards for yourself and everyone you work with, you will drive engineering best practices and be constantly looking for ways to make the systems you own better. You have great communication skills and enjoy working in a fast-paced, collaborative team environment.
