Senior Software Engineer, Transportation Financial Systems

We re looking for an SDE3 who s excited about running a time-critical, globally available service, and solving complex scalability problems in distributed systems. You ll be the tech lead of a team that moves fast, maintains a high operational bar, and contributes to open source regularly (multiple maintainers on the team).

Key job responsibilities
. The Engineer in this job is expected to make the design (High level and Low level) decisions, own end to end (depth) for specific set of features while having breadth on rest of the features and provide technical guidance for the Junior members in the team.
Design and implement scalable solutions using Scala or Java, and AWS services
Mentor team members and collaborate across functions to deliver integrated solutions
Drive continuous improvement through code quality, testing, and technical debt reduction
Provide hands-on development for complex features while maintaining engineering excellence
Partner with product teams to understand requirements and deliver localized solutions.

Basic qualifications
* 5+ years of non-internship professional software development experience
* 5+ years of programming with at least one software programming language experience
* 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
* Experience as a mentor, tech lead or leading an engineering team

Preferred qualifications
* 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
* Bachelors degree in computer science or equivalent

What will you own?
You will be part of building the ship cost allocation platform to accurately reflect the actual economics of the Amazon transportation globally. With the dynamic and the growing nature of the transportation business, we need an innovative and simple solution to cost allocation to better inform operational and profit intelligence decisions. Allocation of transportation costs to the items shipped requires building algorithms that are far from trivial and involves deep business understanding, tech acumen, mathematics and machine learning as well. This data will affect the profitability computation for Amazon, to accurately charge businesses for their expenses, and impacts product selection.

You will build highly scalable systems to compute cost of transportation for every item shipped by Amazon. These systems are the authority for ship cost computation in Amazon. You will work with economists to find right model and cost driver to build solutions and algorithms to allocate costs.

A day in the life
The following are the day to day activities:
1. Feature development
2. Peer Code and design review
3. Interact with internal and external stakeholders (Dev and QA) on clarifying the requirements, resolving the dependencies etc.
4. On-call rotation
