Calliere - Senior Software Engineer - GO

Client: Calliere

Location: Charlotte, ON, ca

Contract: Freelance

Job Description

This is a remote position. We operate as a fully distributed team — no headquarters, no in-office requirement. You choose the environment where you do your best work. We’re looking for a backend-focused software engineer who is passionate about building secure, scalable infrastructure from the ground up.

Day-to-Day Responsibilities

• Join a small, senior team at the early stages of building a product from scratch.
• Convert product requirements into thorough technical design documentation.
• Architect and implement backend services built to handle enterprise-scale demand.
• Design systems with high availability and fault tolerance in mind.
• Embed security thinking at every layer — application, API, and infrastructure.
• Own API design across both public-facing and internal service boundaries, including schema modeling and integration patterns.
• Work cross-functionally with product and design stakeholders throughout the development lifecycle.
• Thrive in a remote-first environment using a blend of synchronous video calls and async communication.
• Stay current with emerging technologies and approach new challenges with genuine curiosity.
• Take part in engineering hiring by conducting interviews and evaluating candidates.

Requirements

What We’re Looking For

Core qualifications:

• Strong working knowledge of Go.
• Hands-on background with microservices and service-oriented architecture.
• Comfort writing raw SQL and designing relational database schemas, preferably in Postgres.
• Practical experience with CI/CD workflows and container orchestration via Kubernetes.
• Prior work building observability tooling — metrics pipelines, alerting systems, and distributed tracing.

Nice to have:

• Working knowledge of modern auth protocols such as OAuth 2.0, SAML, OIDC, or WebAuthn.
• Exposure to corporate IT and security tooling (device management, endpoint protection, etc.).
• Experience designing and maintaining audit log systems.
• Familiarity with regulatory and compliance frameworks (e.g. SOC 2, ISO 27001, GDPR, CCPA).
• Understanding of PKI infrastructure and certificate management.

Benefits

• Fully remote, with core overlap expected during North American business hours.
• Twice-yearly in-person team gatherings.
• Flexible, open vacation policy — with a genuine expectation that you use at least two weeks annually.
• 16 company-designated holidays per year, including a winter break period.
• Medical, dental, and vision coverage for employees and their dependents.
• 12 weeks of paid parental leave.
