[Hiring] Senior Backend Engineer @CXM

Role Description

We are looking for a Senior Backend Engineer who will own our connector layer and everything downstream of it:

• Building and owning the connector and adapter layer, so that adding or replacing a provider becomes configuration and a thin adapter rather than a new integration each time.
• Migrating payment methods from redirect flows to server-to-server and embedded flows where the provider supports it, and measuring the result.
• Owning everything downstream of the orchestration layer: reconciliation, transaction status handling on our side, method configuration and payment flows into the client portal.
• Making transaction status reliable end to end, through active status polling, idempotent processing and reconciliation.
• Building observability over transaction status and provider performance across the estate.
• Specifying the behaviour we need from the orchestration platform: transaction state machine, idempotency, polling, routing and cascading rules.
• Supporting integration work for our card programme.
• Extending the same integration set to acquired entities as configuration rather than a new build each time.

Qualifications

• 5+ years in backend engineering, strong in TypeScript, Node.js, comfortable in relational databases.
• Production experience with payment systems: authorisation, callbacks, refunds, reconciliation and retry behaviour.
• Practical understanding of idempotency, asynchronous status handling, transaction state machines and designing for partial failure.
• Experience integrating third-party APIs of uneven quality.
• The ability to own a service rather than close tickets: architecture decisions, standards and root cause fixes.
• English and Russian at a working communicative level.

Requirements

• Exposure to .NET for work touching the client portal will be a significant plus.
• Experience with APM and local rails in Asia, Africa or LATAM rather than cards alone.
• Experience with bank transfer rails, virtual accounts, QR-based methods, mobile money etc.
• Event-driven patterns in production: transactional outbox, idempotent consumers, sagas.
• Background in brokerage, crypto payments, orchestration or another high-volume payments environment.
• Active use of AI tooling in daily work.
• Ability to work independently and make decisions without constant oversight.
• Proactive mindset: willingness to propose improvements, fixes, new approaches.

Benefits

• Fixed monthly compensation of [based on experience].
• Fully remote work within GMT to GMT+4, with no relocation required.
• Ownership of the connector layer and everything downstream, with direct influence on what the orchestration platform becomes.
• Engineering problems that are not CRUD: asynchronous status across dozens of providers, partial failure, and local payment rails in emerging markets.
• Scope that grows with the business: a card programme, new entities and new payment products.
• Corporate AI tooling as part of the working process.
