Technical Lead / Senior Backend Engineer - Remote

General Description

The Technical Lead / Senior Software Engineer is responsible for designing, building, and modernizing high-performance backend services within a large-scale, high-concurrency platform.

This role requires deep expertise in Golang, distributed systems, and event-driven architecture, with strong ownership across architecture, system reliability, and engineering quality standards.

The ideal candidate combines hands-on coding excellence with strong system-level thinking, acting as a key technical driver in rebuilding and re-engineering core platform services from the ground up.

You will help deliver highly scalable wallet, transaction, and core backend systems operating within a regulated, high-throughput environment.

Nature of the Tasks

• Design and implement scalable, high-performance backend services using Golang

• Architect and build distributed systems within an event-driven microservices environment

• Contribute to wallet, ledger, payment, and core transaction domains

• Ensure concurrency safety, data consistency, and fault tolerance in high-scale systems

• Drive system reliability through proper error handling, retry mechanisms, and failure isolation

• Integrate services with message brokers (Kafka or equivalent) for asynchronous processing

• Design and optimize RESTful and internal APIs with production-grade performance

• Participate in architecture discussions and document trade-offs and system decisions

• Lead or contribute to code reviews, ensuring high engineering standards

• Support production systems, incident resolution, and performance optimization

• Collaborate with Product, Compliance, and DevOps teams to ensure regulatory alignment

• Contribute to CI/CD practices and cloud-native deployments

Required Experience & Qualifications

• 7–12+ years of backend engineering experience

• Strong production experience with Golang

• Deep understanding of concurrency, goroutines, channels, and memory management

• Solid experience designing microservices and distributed systems

• Experience with event-driven systems (Kafka, RabbitMQ, or equivalent)

• Strong knowledge of transaction systems, idempotency, and data consistency patterns

• Experience working in high-scale, high-availability environments

• Familiarity with Kubernetes and containerized deployments

• Experience in fintech, payments, or other regulated transactional systems is highly preferred

• Strong understanding of system design principles and architectural trade-offs

Technical Expertise

Hands-on experience with:

• Languages: Golang (primary), experience with Java or other backend languages is a plus

• Architecture: Microservices, Event-Driven Systems, Distributed Systems

• Messaging: Kafka, RabbitMQ (or similar)

• Databases: PostgreSQL, MySQL, Redis (or equivalent)

• Containerization & Orchestration: Docker, Kubernetes

• API Design: REST, gRPC (nice to have)

• CI/CD: Jenkins, GitLab CI/CD, or equivalent

• Cloud Platforms: AWS, GCP, Azure (cloud-native environments)

Nice to Have

• Experience building wallet or ledger systems

• Exposure to reconciliation workflows and financial audit requirements

• Experience handling at-least-once message processing and idempotent consumers

• Strong understanding of performance profiling and production debugging

• Prior experience leading technical initiatives or mentoring engineers

Key Competencies

• Strong system design and architectural thinking

• Ownership mindset with high accountability

• Ability to operate in high-scale, high-pressure environments

• Strong problem-solving and analytical skills

• Clear and structured communication

• Ability to align teams on technical direction
