Job description

At Capably, we’re building technology that helps businesses operate more efficiently, eliminating complexity and friction with seamless automation.

As a Senior Software Engineer at Capably, you’ll build the systems that make enterprise AI actually work in production. You’ll design, ship, and scale the core platform capabilities that allow customers to deploy intelligent workflows with the reliability, security, and control real businesses require.

This is a hands-on engineering role with high ownership. You’ll work across product, infrastructure, and AI systems to turn ambitious ideas into dependable software, building the foundations that make complex, highly customised automation possible at scale.

Build and Scale Production-Grade Systems

We believe great engineering is not just about writing code—it’s about building systems that last. You’ll help architect and implement the platform, services, and workflows that power Capably’s product, with a sharp focus on performance, reliability, maintainability, and user impact.

You’ll work closely with product, design, research, and deployment teams to understand customer needs and translate them into elegant technical solutions. From workflow orchestration and integrations to internal tooling, observability, and platform infrastructure, your work will directly shape how Capably delivers value in real enterprise environments.

Design, build, and maintain core platform and product systems

Ship reliable, scalable software that supports complex AI-driven workflows in production

Improve system performance, observability, and operational resilience across the stack

Collaborate with cross-functional teams to turn product requirements into technical solutions

Contribute to architecture decisions, engineering standards, and development best practices

Identify bottlenecks, reduce technical debt, and continuously improve developer velocity

Your work will help Capably strengthen its position as an enterprise AI platform built for reliability, governance, and real-world deployment. You’ll play a key role in building the infrastructure and product capabilities that differentiate Capably from agent-only approaches and make automation dependable at scale.

Success in this role means combining speed with sound judgment. You’ll be expected to ship quickly, but never carelessly—making smart technical decisions that support both immediate product needs and long-term platform quality. You’ll take ownership of meaningful parts of the system and help raise the bar for engineering across the company.

By staying close to customer problems and engineering fundamentals, you’ll help ensure Capably continues to push the standard for enterprise AI software. Your ability to build robust systems, navigate ambiguity, and execute with precision will be essential to our next stage of growth.

What You Bring:

Strong experience building and shipping production software in fast-moving environments

Proficiency in backend and/or full-stack engineering, with strong system design fundamentals

Ability to write clean, maintainable, high-quality code and operate effectively across the development lifecycle

Experience designing scalable systems, APIs, integrations, and distributed services

Strong debugging, problem-solving, and performance optimisation skills

Ability to work cross-functionally and take ownership from idea to production

Experience with AI systems, workflow automation, or enterprise software is a strong plus

Your work will help Capably build software that is not only powerful but also trusted in production. If you’re excited to solve hard engineering problems and help define the infrastructure behind the next generation of enterprise AI, we’d love to hear from you.
