Staff Backend Software Engineer

Team: IT

Location: Romania

Commitment: Full-time

Workplace Type: remote

Accountabilities

• Design, develop, and maintain core components of a distributed transaction platform.

• Build resilient systems that preserve data correctness, tenant isolation, and auditability, including when failures occur.

• Improve scalability as transaction volumes and the number of institutions per node increase, maintaining predictable latency and database performance.

• Produce clear technical design documents and provide constructive, detailed reviews of architecture proposals and code.

• Integrate AI coding agents into daily development workflows and improve specifications, context, and review practices to ensure generated code is safe for production.

• Collaborate with product, compliance, and customer-facing teams to translate regulatory obligations and customer needs into reliable software.

• Take end-to-end ownership of production systems, including tracing, alerting, incident response, and post-incident follow-ups.

• Mentor other engineers, share technical expertise, and contribute to the teams engineering standards.

• Participate in the on-call rotation to support platform reliability and operational continuity.

Requirements

• Typically 8+ years of backend engineering experience, with a track record of delivering complex technical projects end to end and helping other engineers grow.

• Strong distributed systems design expertise, including asynchronous processing, failure handling, and systems where correctness takes priority over feature delivery.

• Strong Go experience, or substantial production experience with another statically typed backend language such as Java, Kotlin, Rust, or C#, with the ability and motivation to start shipping Go code within the first few weeks.

• Deep PostgreSQL knowledge, including schema design, query planning, locking, transaction isolation levels, live database migrations, and multi-tenant data management.

• Practical cloud engineering experience with AWS or GCP, including IAM, networking, managed databases, queues, and storage. Ability to read and modify Terraform and troubleshoot production issues using traces and logs.

• Daily experience using AI coding agents such as Claude Code or Cursor, including writing specifications, providing context, decomposing tasks, critically reviewing generated code, and understanding where these tools can fail.

• Strong written communication skills, with the ability to explain technical decisions clearly and concisely in a remote environment that relies on documentation and asynchronous collaboration.

• Solid security fundamentals for handling sensitive data, including encryption in transit and at rest, key management, data minimization, and least-privilege access.

• Familiarity with any of the following is an advantage: applied cryptography, decentralized identity protocols such as DIDs, verifiable credentials and DIDComm, regulated finance, payments, compliance frameworks such as the Travel Rule, AML, ISO 20022, SOC 2 or ISO 27001 controls, crypto and blockchain concepts, Node.js, TypeScript, queue and workflow systems, or modern observability tooling.

• Blockchain experience is not required. Candidates from a broad range of backgrounds are encouraged to apply, including those returning to work after a career break or progressing along a different career path.
