Senior Software Engineer - Backend - Card & Transaction Platform *EU/UK remote* (m/f/d)
Pliant · Remote · Germany · 1mo ago
ABOUT US
Pliant is a modular B2B payments platform that combines commercial card issuing, payment accounts, FX, and spend management in one system — adapting to existing setups rather than requiring customers to replace them.
Businesses across industries such as travel, e-commerce, and insurance use Pliant to manage complex payment workflows with cards, backed by credit lines Pliant underwrites itself.
Fintechs and software platforms embed Pliant's payment infrastructure into their own products, from API-based Cards-as-a-Service to fully white-label solutions. Banks use Pliant's Card & Spend OS, the customer-facing interface, on their own infrastructure to run card programs.
Founded in 2020 and headquartered in Berlin, Pliant serves 5,000+ businesses and 40+ partners across Europe and the United States. A principal member of Visa and Mastercard, Pliant issues commercial cards in 13 currencies across 32 countries — under its own European e-money license and with licensed partners in the UK and US.

ABOUT THE ROLE
The Card & Transaction Platform team keeps Pliant's most critical backend flows running: card issuance and transaction processing. The team holds itself to a high availability bar, getting there through solid engineering and a no-blame culture rather than heroics. With a fast-growing customer base and rising request volumes, this role is for an experienced backend engineer who anticipates problems and prevents them, building and shipping new product features on Java/Spring Boot microservices just as much as keeping them fast and reliable.
WHAT YOU'LL DO
Define, measure, and improve SLOs/SLAs and error budgets for critical services.
Help evolve and scale the platform to keep pace with a growing customer base and rising request volumes.
Stay ahead of problems: spot weak points, risky patterns, and capacity limits early and address them before they affect customers.
Share in a fair, well-compensated 24/7 on-call rotation and help lead incident response, from mitigation to blameless postmortem and follow-through.
Own observability across dashboards, alerting, tracing, and logging (we use Datadog), and drive performance improvements across latency-sensitive paths.
Design, build, and ship new product features end-to-end across Java/Spring Boot microservices, from API design through to rollout.
Balance feature delivery with continuous improvement, collaborating with product and other engineering teams to turn requirements into reliable, well-tested services.
WHAT YOU'LL BRING
5+ years of experience building and operating modern distributed backend services on a Java/Spring Boot stack, with AWS cloud services, Kafka, and PostgreSQL.
A track record with high-availability systems where reliability genuinely matters, including experience scaling systems under growing load.
Fluency with a modern observability stack and solid SLO/SLA thinking.
A proactive, ownership mindset: you look for the next problem before it happens rather than waiting for the alert.
Comfortable owning features end-to-end, from design and implementation through testing and delivery.
Hands-on, proven experience using AI effectively as an engineering tool, not a substitute for engineering judgment.
Nice to have (genuinely optional, please don't self-select out):
Payments, card issuing, or transaction processing domain experience.
Experience with PCI DSS certification or operating in a PCI DSS environment.
Exposure to fraud detection or prevention.
Experience with chaos/resilience testing, capacity planning, or load testing.
Hands-on experience implementing safe deployment practices such as canary deployments, blue/green, or progressive rollouts.
