[Hiring] Senior Backend Engineer @CXM Direct LLC

Role Description

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

• Building a canonical adapter layer for providers to plug in rather than get built one by one.
• Moving payment methods to server-to-server and embedded flows.
• Making transaction status reliable and observable across the estate.
• Acting as the payments function's technical counterpart to the orchestration platform team.

Your responsibilities will include:

• Building and owning the connector and adapter layer for easy provider integration.
• Migrating payment methods from redirect flows to server-to-server and embedded flows.
• Owning everything downstream of the orchestration layer: reconciliation, transaction status handling, method configuration, and payment flows into the client portal.
• Ensuring reliable end-to-end transaction status through active polling and reconciliation.
• Building observability over transaction status and provider performance.
• Specifying the behaviour needed from the orchestration platform.
• Supporting integration work for our card programme.
• Extending integration sets to acquired entities as configuration.

Qualifications

• 5+ years in backend engineering.
• Strong in TypeScript and Node.js.
• Comfortable with relational databases.
• Production experience with payment systems: authorisation, callbacks, refunds, reconciliation, and retry behaviour.
• Practical understanding of idempotency, asynchronous status handling, and transaction state machines.
• Experience integrating third-party APIs of uneven quality.
• Ability to own a service: 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 is a significant plus.
• Experience with APM and local rails in Asia, Africa, or LATAM.
• Experience with bank transfer rails, virtual accounts, QR-based methods, mobile money, etc.
• Experience with event-driven patterns in production.
• Background in brokerage, crypto payments, orchestration, or high-volume payments environments.
• Active use of AI tooling in daily work.
• Ability to work independently and make decisions without constant oversight.
• Proactive mindset: willingness to propose improvements and new approaches.

Benefits

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

What the first year looks like

• In the first months, take over the integration codebase and strengthen transaction status handling.
• By mid-year, the adapter layer is in place, and new providers go live against it.
• In the second half, migration to server-to-server and embedded flows runs as a programme across methods.
• A Systems Analyst will take over instrumentation and verification as the team grows.

Recruitment process

• HR interview covering background, motivation, and fit.
• Technical interview on backend engineering and the payments domain.
• Home task as a case from real needs.
• System design and problem-solving interview.
• Final interview with a senior stakeholder.
