Descrizione del lavoro

Wirelesslogic seeks a backend-focused software engineer to build and operate a high-volume billing platform. You will develop TypeScript/NestJS services and React interfaces, translating complex billing rules into robust data models and service boundaries.

You will design event-driven workflows with Kafka/RabbitMQ, tune PostgreSQL schemas for large data sets, and contribute to production readiness and incident response.

Competenze

• Strong hands-on TypeScript and NestJS experience.
• Experience designing event-driven or asynchronous systems with messaging tech.
• Strong PostgreSQL skills, including data modeling, indexing, query tuning, and performance diagnosis.
• Ability to take features through full software lifecycle, including testing and production operation.
• Sound engineering judgment around reliability, testing, type safety, and incremental modernization.
• Clear communication and collaboration with engineers, product partners, and stakeholders.

Mansioni

• Design and maintain TypeScript and NestJS services for billing workflows, with attention to correctness, testability, and operability.
• Build React interfaces that help users work with billing data and processes.
• Work with product partners and domain experts to translate billing rules into clear data models, code, and service boundaries.
• Develop asynchronous, event-driven workflows using Kafka or RabbitMQ, including reliable retries, ordering, idempotency, and recovery.
• Model and tune PostgreSQL schemas and queries for large data sets and demanding processing workloads.
• Help extract capabilities from a mature platform into services through staged changes and safe cutovers.
• Own work from refinement and design through implementation, automated testing, release, and production support.
• Contribute to technical decisions, code quality, observability, operational readiness, and incident follow-up.

• Own work from refinement and design through implementation, automated testing, release, and production support.
• Contribute to technical decisions, code quality, observability, operational readiness, and incident follow-up.

Requirements

• Strong hands-on TypeScript and NestJS experience, with the ability to contribute to React applications.
• Experience designing event-driven or asynchronous systems with Kafka, RabbitMQ, or comparable messaging technology.
• Strong PostgreSQL skills, including data modeling, indexing, query tuning, and performance diagnosis.
• Ability to take meaningful features through the full software lifecycle, including testing and production operation.
• Sound engineering judgment around reliability, testing, type safety, technical debt, and incremental modernization.
• Clear communication and collaboration with engineers, product partners, and business stakeholders.

Nice to have

Experience with billing or other financially sensitive data processing, distributed systems, service-level objectives, Grafana, and production incident investigation. The source also emphasizes sharing knowledge through reviews, pairing, and documentation, and using AI-assisted tools thoughtfully.

Benefits and work setup

• Fixed-term contract for 12 months.
• The role is based in Poland, with a remote/hybrid approach and collaboration with the local squad.
• The source mentions training and ongoing support.
