About the role
Sphere Pay is looking for a full-time Core Engineer working remotely. As a Core Engineer at Sphere Pay, you will work on the core systems used to support our users, their accounts, and the various services we provide them through our APIs. The work you do directly supports the products we offer to users and is the backbone of our service offering; you will regularly have an outsized impact on Sphere Pay’s reputation with our customers and why they choose to use us. Key Responsibilities: Product Lifecycle Management: Work on long term major systems supporting our customers and their accounts. You will be proposing, documenting, developing, maintaining, upgrading, and re-evaluating long lived systems which may need to change to support our business as the scope of what we work on expands and the number of users and transactions we support increase. Sales Relationship: Work closely with our sales team to understand the current pain points of our customers as well as the kinds of products they want. Develop product and feature documentation such as product readiness documents (PRDs) to investigate work requirements, and if deemed a priority implement those solutions. Integration of External Services: Work with our third party vendors to integrate various systems from KYC / AML to foreign exchange APIs, banking aggregators, etc. You will be expected to handle communication with our vendors during the integration process and to represent Sphere Pay’s engineering team. Integration of Sphere Domains: Work within Sphere Pay’s engineering team to expose core functionalities such as web3 / crypto, banking, and more directly to end users via our API. You should be comfortable communicating across domains to understand our product better and represent a complete solution to our customers. Bug Fixing & Issue Investigation: Research issues raised by our clients & customers with our product health and availability. You will help resolve the highest priority issues to minimize or prevent service interruptions to our customers. Development: Write high-quality code with an emphasis on scalability, stability, and traceability. The features and products you support in many cases determine whether or not our customers can onboard, can open an account, or can transact; making sure that these systems are resilient and log failures in trackable and fixable ways is paramount. Documentation: Create and maintain technical documentation, including client facing documentation, internal documentation, product guides, and vendor integration notes for all of the products you maintain. You will be expected to similarly rely on this documentation when taking on tasks to update long lived systems. Testing Environments: Maintain a persistent test environment and sandbox which mirrors production closely enough that other domains can test major features in a dry environment prior to going live. You will also be expected to maintain unit and integration tests for any code you write to ensure system stability. Qualifications: • Bachelor's or Master's degree in Computer Science, Engineering, or a related field is a plus; alternatively an extensive history of independent code development. • Proven experience as a software engineer, with a minimum of 6 years of experience. • Experience taking products to production and managing their maintenance, scaling, and changes / upgrades. • Experience within payments, crypto / web3, and fintech are plus but are not required. • Proficiency in common web technologies and either a proficiency with or a willingness to learn: TypeScript, GCS, PostgreSQL, etc. • Excellent problem-solving skills and the ability to work in a fast-paced, collaborative environment. • Strong communication and interpersonal skills. Sphere Pay is committed to fostering an inclusive and diverse work environment. We encourage applicants from all backgrounds and experiences to apply.
