Job Description:

** The Role
** Fidelity Labs is looking for a Principal level engineer to help build out our API Platform. This project is still in early stages and has room for exciting greenfield development!
** The Experience and Skills You Bring
*** Attention to detail:
An eye for detailed code review, writing clean code, and thoroughly reading documentation.
* Leadership: A track record of mentoring junior engineers and explaining to them not only what standard methodologies are, but why they exist. As a startup, we can't anticipate everything that needs to happen every sprint, and we're looking for developers who can see gaps and move to fill them, while still collaborating with the rest of the team. We also work with a lot of other teams within Fidelity, so we also need people with experience with cross-team collaboration.
* Shipping features and debugging production incidents in event-driven distributed systems.
* Excellent technical interpersonal skills and a desire to make existing documentation better both for fellow developers and external customers. We're interested in people who can take dry, abstract concepts and refine them into something even a non-technical audience can understand.
* Curiosity:
Interest in the tools and abstractions used and how they work. Looking for someone who loves to have a detailed understanding of the technology they depend on and are interested in continually improving processes, whether that be questioning whether the default index type on the relational database should be a B-tree or sharing a useful new keyboard shortcut in the team's text editor.
* Type Script expertise: A strong instinct for writing accurate and specific type annotations, and knowledge of features such as the distinction between classes, types, and interfaces. Candidates with experience in other languages such as Go, Java, Ruby, and Python are also welcome to apply, as long as there is a proven track record to learn new languages.
* Technical Expertise:
Deep expertise in software architecture, cloud services, microservices, and event-driven paradigms.
* Production Expertise:
Significant experience shipping features, debugging production incidents, and optimizing performance in event-driven distributed systems.
* Experience with using logging and observability platforms like Datadog and Amazon Cloudwatch.

* Experience:

Minimum of 7 years in software development, with a focus on platform engineering or API development.

Experience with AWS cloud services such as ALB, Aurora, and S3, and relational databases such as Postgre

SQL desired.

Experience with identity management platforms like Auth0 is a bonus
