Engineering

Team structure

At Form3, we are firm believers that our teams should have autonomy and ownership of their work, and of the entire platform too. Our teams are responsible for every aspect of the work they are delivering, including testing, deployment and infrastructure. This gives our engineers a wide variety of challenges and growth opportunities.

Markets

Our markets teams build and run critical payment processing services in the UK, Europe and internationally. We support a wide variety of payment processing schemes such as FPS, BACS, SEPA, SWIFT and more.

Key technologies: Go, Java

Here are some of the exciting things they do:

01

Implement and maintain the payment gateways which link our core platform with all the external payment schemes

02

Wrangle a wide variety of different integration technologies into our secure, resilient, cloud-native platform

03

Build microservices in Go (with the occasional older Java microservice thrown in), running on ECS or Kubernetes

04

Scale processing to millions of payments a day, while exceeding strict performance and reliability benchmarks

05

Work closely with the product and business teams in each market to build complete customer propositions

Transaction Management

Our Transaction Management team builds and maintains shared services across the platform while being responsible for our value-add proposition to the customers as well

Key technologies: Go, Java, Kubernetes, NATS Jetstream, Cockroach DB, large distributed systems

02

Use infrastructure-as-code (Terraform) to automate the build and maintenance of standardised stacks across multiple cloud providers (AWS, GCP, private cloud)

03

Work with Kubernetes and cloud-native data and messaging services such as Cockroach DB, NATS and Cilium to build our next generation platform

04

Design, build and maintain a highly resilient cross-cloud architecture to allow us to run active-active across multiple cloud providers

05

Build and maintain our private cloud stack running Kubernetes in our own data centres, adapting all our cloud-native technologies to this environment

06

Design, build and maintain a platform where any component (from networks, routers, servers, to OS and microservices) can be removed, replaced or upgraded without causing downtime

R&D Operations

Internal tools drive the productivity of our entire engineering team, and help us deliver software securely and at speed. Our tooling teams build and maintain our extensive developer tooling ecosystem.

Key technologies: Terraform, Kubernetes, Go, Github, AWS, Grafana, ELK

Here are some of the exciting things they do:

01

Build, deploy and maintain all Form3’s internal tooling using Go, Terraform and various open-source tools

02

Work together with other teams to identify, gather requirements and deliver tools that continually improve our development and delivery processes

03

Continually improve and scale our CI/CD tooling, logs, metrics, alerting and tracing platform, and remote access technologies

04

Work closely with InfoSec to secure all aspects of our internal tooling

05

Have a passion for software development best practice, and understand how tooling can support that

Data services

Our teams in the Data Services business line are providing services both internally to our teams (our internal customers) as well as externally to our (external) customers, to enable and support them on effectively extracting the most possible value out from their data.

Key technologies: Go, Java, Terraform, Kubernetes, CockroachDB, NATS, Iceberg

Here are some of the exciting things they do:

01

Address and provide solutions to cross-cutting challenges that span across the organisation as well as extend to a global scale

02

Design, build and maintain a Financial Crime Prevention Orchestration Platform as a Service for external customers to detect fraudulent transactions in their Banking systems, and to potentially prevent crimes and scams that has not only monetary but emotional impact as well on a global scale

03

Design, build and maintain a DataMesh Platform as a Service for internal customers (other teams within the company) to support them with the platform, and the appropriate processes and tooling to efficiently access, share, manage and maintain high-quality data products for internal as well as external use.

InfoSec

Form3 have an extensive team of defensive and offensive engineering teams that work together with our security officers.

Our security teams work closely together with all our other engineering teams to ensure that we maintain the highest standards of security on our platform.
