Collaborate on and present work to a range of stakeholders – executives, engineers, product managers, business leaders, UX and visual designers, and other researchers. Stay current on emerging research, industry, and technology trends. Drive research for existing experiences while also identifying opportunities for the future product development. Collaborate with other insights teams such as other Researchers and Designers, product leaders, and engineering partners in the larger organization representing other organizations and products, Data Scientists, members of the Builder Insights team to align research findings and recommendations to stakeholders. assessing proposals, budget considerations, contracts, etc) Work from high-level requirements and ask the right questions to gather all relevant information to guide research approach. Create scalable and repeatable process and technical solutions to allow Research and Design to scale Select, consult with, and manage research projects with vendors (i.e. Run end to end research (i.e., user interviews, remote usability testing, surveys, card sort, tree tests, etc) with a particular focus on customer experience improvements.

Key job responsibilities Be the Research lead for projects that touch numerous measurement aspects of the Amazon software builder experience. * Devise intuitive and and creative methodologies to visualize quantifiable information for users which can be presented in a variety of contexts, both individually and in concert with other data streams. Within the Builder Insights team, we are looking for design and research support to help in the following areas: * Create a platform of tooling to surface meaningful data and actionable insights to Amazon builders, factoring in multiple scenarios of business-thinking from the individual builder level to the highest forms of leadership.
At an everyday level, we provide personalized insights to teams to help them make decisions to make their day-to-day lives at Amazon better. At the planning level, our insights team will help ASBX and other teams within Amazon direct investments to the best places (tools, training, ways of working) which will drive the greatest benefits to software builders. To reach that goal, we strongly believe insights shape creation of the best software builder experience in the world.

From training for new employees and surfacing actionable recommendations based on insights from service metrics to streamlining code deployment and integrating customizable tooling to automate human-repeatable tasks across our portfolio, we are looking for every opportunity to make Amazon the best place to build software. In early 2022, we brought existing and nascent teams under a new banner, Amazon Software Builder Experience (ASBX), with a mission to modernize our processes and tools so software builders of all types can focus on innovating, rather than waste time wrestling with outdated and obtuse mechanisms.

Our extensive experimental evaluation on real and synthetic data showcases the efficacy of our method into recommending optimal (or close to optimal) distribution keys, which improve the cluster performance by reducing network cost up to 32x in some real workloads.Īmazon is radically rethinking how to improve the experiences for all of its software builders. Thus, we propose BaW, a hybrid approach that combines heuristic and exact algorithms to find a good data distribution scheme. Our theoretical analysis proves that “Distribution-Key Recommendation” is NP-complete and is hard to approximate efficiently. We then formulate the “Distribution-Key Recommendation” problem – a novel combinatorial problem on the Join Multi-Graph– and relate it to problems studied in other subfields of computer science. To formalize the problem, we first introduce the Join Multi-Graph, a concise graph-theoretic representation of the workload history of a cluster. We describe a generally-applicable data distribution framework initially designed for Amazon Redshift, a fully-managed petabyte-scale data warehouse in the cloud.
How should we split data among the nodes of a distributed data warehouse in order to boost performance for a forecasted workload? In this paper, we study the effect of different data partitioning schemes on the overall network cost of pairwise joins.
