Full Stack Engineer - 90% back end/10% front end Employment Type: Contract Reference: - BH-371382 Full Stack Engineer - 90% back end/10% front end
Looking for a back end heavy full stack engineer who has experience with large scale systems, has Java and is experienced with migrations. If someone has experience migrating large scale systems from Ruby to Java than they would be a home run! This is not only someone who is well versed in backend development but also has a solid product sense and likes to work with best in class, product managers, designers, and data scientists.

The large-scale system was originally built on ruby on rails monolithic architecture which has been deprecated, however, the team still has several products built on the old stack. These need to be migrated to a more modern service-oriented architecture.
Architecture Includes:
Message spam education.
--- When a user receives a suspicious message, we show a popup indicating that they should be careful with this message which helps stop phishing attacks & scams.
--- This system must be migrated off the monolithic architecture to a new service with proper testing & monitoring.
Child Exploitation Imagery.
--- The Service detects child exploitation images & immediately removes them & bans the user.
--- This system needs to be migrated to our modern architecture & also needs performance improvements.
Queues (Content Moderation).
--- Many of the mitigation solutions involve agents manually reviewing content & making decisions on next steps - Banning users/sending educational emails.
--- Multiple queues need to be migrated which are critical in responding quickly to several different kinds of fraud & scams.
Lead and/or assist with other migrations & fraud projects.

--- Support all aspects of agile SW development - Design, implementation, testing, & deployment.
--- Build/maintain Java based microservices having well defined APIs that are reliable & scalable.
--- Architect/implement solutions to improve reliability, observability, efficiency, & performance of existing systems
--- Troubleshoot, debug, & maintain existing systems.

--- Strong experience developing in Java & familiarity with its unit testing frameworks.
--- Experience working with large-scale SW systems is a must have.
--- Strong debug & optimization skills with a focus on building reliable systems.
--- Strong comm skills, excited to learn & collaborate with the engineering team.
--- Experience with Ruby is ideal but not necessarily a hard requirement. Given this is focused on migrating from Ruby to Java this experience would be beneficial though.
--- Previous experience with large systems focused on fraud, payments, or other Trust related systems is a plus.
