FULL DESCRIPTION

[Employer hidden — view at passion-project.co.uk] is seeking a Staff Software Engineer for their Global KYC and Onboarding squad. The role involves architecting and implementing domain-driven technical solutions, leading engineering teams, and contributing to the company's engineering goals. The ideal candidate has 10+ years of software engineering experience, particularly with Java or other JVM-based languages, and experience in architecting large-scale systems.

Job Description

About the role:

We are the Global KYC and Onboarding squad in the Servicing department and we have a mission: to enable teams at [Employer hidden] to expand and fine-tune the business in a "config change" manner all across the globe, while remaining compliant and safe for the customers. There are three teams in the squad: Business Onboarding Verification, Personal Onboarding Verification and [Employer hidden] Platform Verification (this is our B2B platform).

What will you be working on?

The current KYC infrastructure has served us well for many years, but we are approaching its scalability limits. For the past few quarters we’ve been busy building a brand new infrastructure, the Onboarding Platform. In collaboration between the teams in the squad and sister teams in other squads, we’ve iteratively launched some of the key components already, but there are still many challenges ahead.

The teams are fully stacked cross-functionally, with ownership spanning across owning FinCrime Controls end-to-end: when they trigger, what they require, the UX of collection and recovery, automation (with in-house ML and external vendors), manual reviews and finally enabling relevant capabilities for customers in the product. We have dedicated Analysts, Designers, Data Scientists and Engineers. We need a very strong Engineering partner to act across the teams and functions in the squad to expedite the work on the Onboarding Platform.

What do you need?

  • 10+ years of software engineering experience, with significant experience in Java or other JVM-based languages.
  • 2+ years of experience in architecting large scale systems with proven ability to propose and implement domain-driven technical solutions capable of scaling along with the business.
  • Willingness to take broad ownership of squad responsibilities (building roadmaps, scoping) while mentoring teams on their technical and product roadmaps.
  • Experience in up-levelling junior engineers and providing guidance to senior engineer via processes and setting a high bar for them to follow
  • You are a proactive, effective communicator who is able to describe technical concepts to non-technical audiences and eager to learn new domains and have a strong bias towards action.
  • Experience leading engineering teams and driving large-scale projects to successful completion across multiple engineering teams is a nice-to-have.

What does success look like?

  • You’ll have found your place in our mission by understanding how to drive engineering solutions and suggesting future challenges
  • You’ll understand our customers and the impact our product makes in their lives
  • You’ll make contributions to the wider engineering goals of the company
  • You’ll inspire a team environment where ideas are shared and openness is valued
  • You’ll help us scale-up and build a world class money product that impacts millions of customers
