The Role:

We are looking for a Principal Software Engineer who remains hands-on and owns delivery — taking full responsibility for designing, building and operating complex backend systems, while contributing to wider architectural direction across Eckoh.

This is a senior role for someone with deep backend engineering experience and a strong track record of delivering complex systems into production. You will be embedded within a team and expected to take ownership of complex backend deliverables end-to-end, from design through implementation, release and operation.

The role requires strong experience with distributed systems, event-driven architecture and messaging platforms. Kafka and RabbitMQ are core technologies within our environment, supporting real-time customer interaction, payment, voice/contact-centre and data processing workloads.

You will work closely with Engineering Managers, Lead Engineers, Product, Architecture, DevOps and Security teams to deliver secure, scalable and maintainable enterprise SaaS systems. As part of the architecture group, you will contribute to company-wide technical direction and standards.

You will mentor engineers, support technical leads and help drive delivery within your team.

Key Responsibilities

Engineering & Delivery

• Own complex backend deliverables end-to-end, from design through implementation, release and production operation
• Design, build and evolve backend services and APIs using Python and TypeScript, supporting existing C++ systems where needed
• Work hands-on across coding, design, code reviews, debugging and production support
• Translate requirements into high-quality, maintainable solutions
• Drive predictable delivery through clear ownership, risk management and disciplined execution

Design & Architecture

• Design scalable, maintainable backend systems aligned to platform and business needs
• Define service boundaries, API contracts and integration patterns
• Design and evolve event-driven architectures using Kafka, RabbitMQ and related technologies
• Make pragmatic architectural decisions balancing performance, scalability, cost and complexity
• Contribute to cross-team architecture and technical standards

Security & Reliability

• Adopt a security-first mindset, embedding security and compliance into system design and operation
• Design systems that are reliable, observable and resilient in production
• Own distributed systems concerns including latency, throughput, retries, back-pressure and failure handling
• Ensure strong observability through logging, metrics, tracing and alerting
• Build and operate services in AWS and Kubernetes using modern DevOps practices
• Participate in incident response and drive systemic reliability improvements

Leadership

• Act as a senior technical leader within your team through hands-on delivery and technical ownership
• Mentor engineers and support technical growth across the team

Must-Have

• Experience operating systems in AWS and Kubernetes with modern DevOps practices
• Experience in enterprise SaaS or regulated environments, applying a security-first mindset
• Demonstrated use of AI-assisted development tools to improve productivity while maintaining code quality and security
