_duckyon Ask HN: Who is hiring? (June 2020)

Vocalink, a Mastercard Company | Multiple roles (Java, Devops) and Engineering Manager | Rickmansworth, London, UK | ONSITE | https://www.vocalink.com/

We are a payments systems company which designs, builds and sometimes operates payments infrastructure. My team is involved with desiging and building real-time/instant payments systems. So think instant bank transfers. This software is run as part of a central infrastructure and all banks, who have signed up for it, connect into it.

We are looking for strong senior Java and Devops engineers. We are very interested in engineers who are willing to push themselves and not just technically.

Please get in touch if you have any further questions: rohit dot aggarwal at mastercard.com
