Paymentology is the first truly global issuer-processor, giving banks and fintechs the technology, team, and experience to rapidly issue and process Mastercard, Visa, and UnionPay cards across more than 50 countries, at scale.

Our advanced, multi-cloud platform, offering both shared and dedicated processing instances, vast global presence, and richer, real-time data, set us apart as the leader in payments.

As a Cryptography Engineer at Paymentology, you'll be working in the Engineering team to build enterprise-level, highly scalable, highly secure financial processing systems that power tens of millions of transactions and tie them to web, mobile, and API interfaces that make it easy for people to issue, redeem and reconcile prepaid and credit cards all over the world.

This position requires the ability to develop high-quality and resilient solutions to meet the rapidly evolving needs of an issuer processor serving an internationally expanding customer base and to communicate effectively at all levels, from providing the right level of details in the status updates on your work to explaining technical trade-offs, technical complexities, and design options so Paymentology can make informed decisions.



What you get to do::

Focussing on cryptography solutions, implementation, and operations across multiple products, you need to understand coding concepts that are relevant to manipulating HSM data and protocols (bits and bytes and how to manipulate them; binary encoding and other encodings of ASCII and numeric data), and ideally, you have done low-level network programming, implemented custom protocols and read raw data from a network.

  • Applied knowledge and experience in cryptographic operations for enterprise-grade application implementation & support: e.g. encryption/decryption processes & algorithms, wrapping, RSA, key exchange, symmetric/asymmetric ciphers, and the difference between HSM and soft HSM.
  • Knowledge of cryptography concepts involved in payments: e.g. PIN translation/validation, CVV generation/validation, EMV Cryptogram, 3DS validation, tokenization, as well as all aspects of PKI.
  • Hands-on experience working with HSM devices: e.g. Thales, Ultimaco, SafeNet, &/or a good grounding in TCP/IP practices.
  • Knowledge of HSM keys e.g., LMK, ZMK, ZPK, IWK, CVK, etc.
  • Experience with programming languages like Java and/or Kotlin, particularly related to API development &/or coding against an HSM.


What you can look forward to::

At Paymentology we value making a difference to the lives of the people who work for us and who live in the communities where we operate. You can look forward to working with a diverse, global team where Paymentologists at all levels play an important part in our global mission to advance the world through payments and make a difference on a global scale.

What it takes to succeed:

We're looking for people that make stuff work with the attitude of a self-starter, and collaborative team player, plus a hard-working personality and a strong drive to complete projects on time and deliver the promised outcomes.

You ll be especially welcome if you additionally have any of these bonus skills:

  • Experience developing at scale (large systems with high volume, high availability, and high TPS requirements)
  • Familiarity with Spring Framework, Spring Webflux or Spring Integration, and reactive programming
  • Experience with relational databases (e.g. MySQL, Postgres, MS SQL Server, Oracle)
  • Experience with AWS or other cloud provider(s)
  • Experience with network frameworks like Netty
  • Experience in financial transaction processing, banking, payments, or related industries.

Above all, we are looking for developers...

  • Who love to write great software.
  • Who are passionate about their craft.
  • Who are curious and willing to continuously learn & improve.
  • Who can decipher a complex set of requirements.
  • Who are excited to collaborate closely with a truly global team.

Whilst...

  • Developing, managing, and maintaining card network transactions at scale.
  • Building best-of-breed backend experiences for our customers, internal and external.
  • Creating and reviewing engineering design documentation.
  • Continuously improving our systems, infrastructure, and processes with a focus on quality & security.
  • Creating features, review each other's code, and collaborate with a diverse set of stakeholders across the company
  • Coaching others (& be coached).
  • Influencing/driving architectural decisions and processes on the platform, from unit testing/documentation requirements to implementation processes.
  • Playing a key part in designing, building, and supporting the next-generation payments platform for the company and its growing customer base.

Let s also not forget languages (not the programming kind); since you will work with colleagues located throughout the world, English is our company language so it's important that you be able to communicate at a fluent level, in both spoken and written form, needing to convey complex information clearly.

Flexible hours may be necessary since we are a fully remote team. You ll need to be able to occasionally shift your work hours to participate in on-call duties and better align with colleagues for the scope of specific projects.
