About your new role:

We’re looking for a Senior Software Engineer to join our growing platform team. In this role, you’ll be a core contributor to the systems that power CommandLink’s SaaS platform — from back-end services and API integrations to the architectural decisions that keep us scalable as we grow. You’ll work closely with product managers, designers, and other engineers in a collaborative, high-trust environment where your judgment matters and your impact is visible.

This is not a ticket-shuffling role. We want engineers who think deeply about the problems they’re solving, advocate for quality, and take pride in what they ship.

What You'll Do:

• Design, develop, and maintain scalable Go services and APIs that power our SaaS platform across a global customer base.
• Lead technical design and architecture discussions for new features and platform improvements, balancing speed with long-term maintainability.
• Build and operate concurrent, high-throughput systems, making deliberate use of Go's concurrency model to keep services fast and reliable under load.
• Integrate with third-party APIs, telemetry systems, and network infrastructure to extend platform capabilities.
• Collaborate cross-functionally with product, design, and engineering teams to define requirements, break down complexity, and ship high-quality features.
• Write clean, testable, well-documented Go and hold your team to the same standard through thoughtful code reviews.
• Identify and resolve performance bottlenecks, reliability issues, and scalability gaps before they become customer problems.
• Mentor junior and mid-level engineers, sharing best practices in software design, testing, and system thinking.
• Participate in on-call rotations and contribute to a culture of operational excellence.
• Takes on additional responsibilities and projects as needed to support the success of the team and organization.

What you'll need for success:

• 5+ years of professional software engineering experience, with meaningful time spent building back-end services in production.
• Strong proficiency in Go, including idiomatic patterns, the concurrency model (goroutines, channels, context), and the standard library, with the judgment to know when to reach for it and when not to.
• Experience designing and building RESTful or event-driven APIs that integrate with external platforms and services.
• Proven experience at a high-growth or fast-paced technology company where priorities shift quickly and engineers own outcomes, not just tasks.
• Hands-on experience with Kubernetes for container orchestration and OpenSearch for search and analytics workloads.
• Solid understanding of relational and non-relational databases, query optimization, and data modeling.
• Comfort working across major cloud environments (AWS, Azure, or GCP), including managed services, IAM, networking fundamentals, and cost-aware architecture.
• Strong written and verbal communication skills in English. You'll be collaborating with distributed teams across time zones.
• An ownership mindset. You don't just close tickets. You understand the product, ask the right questions, push back on unnecessary complexity, and leave the codebase better than you found it.

Bonus Points:

• Experience with workflow orchestration engines like Temporal or Camunda. (Temporal's own engine is written in Go, so this maps directly to how we think about durable execution.)
• Working knowledge of Python for tooling, scripting, or data work.
• Experience with gRPC and Protocol Buffers for service-to-service communication.
• Familiarity with event streaming platforms (Kafka) or stream processing (Flink, Spark).
• Exposure to network engineering technologies such as SD-WAN, VoIP, BGP, or MPLS, or genuine curiosity about how networks work.
• Prior experience working in a fully remote, globally distributed engineering team.
