Our client is a B2B tech company reshaping fiscal compliance through cloud-based solutions for electronic receipts and invoices. As a Senior Backend Engineer (Golang), you are expected to operate at system-architecture level, not just as an individual contributor.
You will work on API-first SaaS platforms in highly distributed, compliance-heavy environments. The role emphasizes end-to-end ownership, architectural thinking, and leveraging AI-assisted development and automation to maximize engineering impact. Your focus is on solving complex distributed systems problems, ensuring reliability, scalability, and long-term maintainability.
Key Responsibilities
- Design, build, and operate resilient, high-performance microservices using Golang with end-to-end ownership (architecture deployment monitoring).
- Work in a Continuous Everything / GitOps environment, deploying frequently with strong confidence in automated testing and observability.
- Design and evolve API-first services and a unified interface that is intuitive, strictly typed, and self-documenting.
- Apply AI-assisted development tools (e.g., code generation, test automation, documentation automation) to reduce boilerplate and improve delivery speed.
- Integrate AI/ML capabilities where they add tangible value (e.g., anomaly detection, error classification, intelligent logging).
- Maintain high-quality documentation for both internal teams and external developers, using automation to keep documentation in sync with code.
- Mentor junior engineers on backend best practices, distributed systems thinking, and efficient, tool-augmented development.
- Actively contribute to architectural decisions and long-term system evolution.
KPIs / Success Metrics
- Stability, reliability, and scalability of backend services in production.
- Quality and consistency of API design and service contracts.
- Reduction of incidents through proactive monitoring, automation, and architectural improvements.
- Code quality, test coverage, and maintainability.
- Adoption and effective use of AI/automation to improve team velocity.
- Contribution to team growth through mentorship and technical leadership.
Must-Have Skills & Experience
- 5+ years of backend development experience, with strong hands-on expertise in Golang.
- Deep understanding of distributed systems, including consistency models, fault tolerance, and system reliability.
- Strong experience designing and maintaining RESTful and RPC-based APIs.
- Hands-on experience with Docker and Kubernetes, with understanding of how applications run in production clusters.
- Solid understanding of OOP, SOLID principles, and backend design patterns.
- Experience or strong interest in using AI tools to improve development velocity and software quality.
- Strong communication skills, able to explain complex technical concepts clearly to diverse stakeholders.
Nice-to-Have / Preferred:
- Experience working in GitOps / Continuous Everything environments.
- Hands-on experience with event-driven and asynchronous systems (Kafka, RabbitMQ, Pub/Sub).
- Experience with cloud platforms, preferably GCP.
- Strong understanding of database trade-offs (relational, document, key-value).
- Exposure to compliance-heavy or regulated domains.
Traits We're Looking For:
- Senior-level ownership and accountability mindset.
- System-thinking approach rather than feature-only execution.
- Pragmatic problem solver with a bias toward automation.
- Curiosity and openness to new tools and methodologies.
- Commitment to continuous learning and engineering excellence.
What We Offer:
- Competitive salary and benefits.
- A dynamic and supportive work environment.
- Opportunities for professional growth and development.
- The chance to work on cutting-edge technologies and projects.
