Senior Software Engineer - Backend Systems at Valency Systems Inc. | LAYIQ

Backend Engineering
Design, build, and own critical backend services — APIs, data pipelines, async workers, and the infrastructure that keeps them running reliably at scale
Make sound architectural decisions and document trade-offs clearly so the whole team can learn from them
Drive platform and reliability investments alongside feature work — the foundational improvements that keep pace with growth
Establish and uphold high standards for code quality, test coverage, and operational excellence
Diagnose and resolve complex performance, reliability, and scalability issues; conduct thorough post-mortems that prevent recurrence
Distributed Systems & Infrastructure
Design and maintain distributed systems that are resilient to failure — applying patterns like circuit breakers, retries, idempotency, and rate limiting where they count
Own the full lifecycle of services from design through deployment, including CI/CD pipelines, containerization (Docker/Kubernetes), and cloud infrastructure
Implement and iterate on observability practices: structured logging, metrics dashboards, distributed tracing, and alerting
Contribute to infrastructure-as-code practices (Terraform, Pulumi, or similar) and cloud cost optimization
Data & Integrations
Design performant, well-normalized data models across relational (PostgreSQL, MySQL) and non-relational (Redis, MongoDB, DynamoDB) stores
Build and maintain data pipelines, ETL/ELT workflows, and integrations with third-party services and external APIs
Apply caching strategies thoughtfully — CDN, in-memory, and application-level — and understand the failure modes of each
Work with message queues and event streaming platforms (Kafka, SQS, RabbitMQ) to build decoupled, async architectures
Security & Compliance
Apply secure coding practices by default: input validation, secrets management, least-privilege access, and protection against common vulnerabilities
Contribute to compliance efforts (SOC 2, GDPR, or similar) with an understanding of how engineering decisions affect data privacy and auditability
Technical Leadership
Be the go-to engineer for hard problems — unblock teammates, provide crisp technical direction, and raise the quality of design reviews
Mentor junior and mid-level engineers through code review, pairing, and direct, constructive feedback
Write architecture decision records (ADRs) and technical documentation that outlast the original project
Partner with Product and Design to scope work realistically, surface constraints early, and deliver with clarity
Represent engineering in cross-functional conversations and earn influence through execution, not hierarchy
