Senior Software Developer

About Optio
Optio Incentives is a global fintech scale-up building software that helps companies design, manage, and operate equity compensation plans. We combine powerful technology with deep domain expertise to help customers stay compliant, run their programs end to end, and deliver a seamless experience to both administrators and plan participants. Our platform supports companies across multiple markets, and as we continue to grow internationally, we are expanding both our product capabilities and our engineering footprint.

This is an exciting opportunity to join a fast-growing company and help shape a strong engineering team in a new market from the ground up.

About the role
We are hiring experienced engineers who can be a main contributor on a team and, for more senior profiles, contribute across multiple teams and drive larger technical initiatives.

You will be hands-on in the codebase and take ownership of outcomes, not just tasks. Depending on your strengths and current priorities, you will work across:

• Market and trading capabilities

• Emerging markets capabilities

• Admin portal

• Participant portal

Tech stack

• GCP, GKE

• PostgreSQL

• TypeScript backend (Node.js and Deno), although we are not tied to these technologies

• React frontend

We use AI tools as part of daily workflows. Experience with agentic flows is appreciated, but not required.

What you’ll do

• Own end to end delivery of meaningful product and platform work, from discovery and design to production and iteration

• Drive architecture and technical design within your area, making pragmatic trade-offs and raising the quality bar

• Improve reliability, correctness, and maintainability through better testing, observability, and operational practices

• Collaborate tightly with Product and Sales on scoping, sequencing, and decisions

• Mentor other engineers through code reviews, pairing, and technical leadership

• For very senior profiles: Lead cross-team initiatives, align stakeholders, and create leverage through shared patterns, tooling, and standards

Who you are

• Senior engineer with strong full-stack capability, or strong backend plus willingness to work across the stack when needed

• Strong in modern web development practices, or able to ramp quickly

• Comfortable taking ambiguous problems and turning them into clear plans and shipped outcomes

• High standards for code quality, production readiness, and long-term maintainability

• Clear communicator who keeps stakeholders aligned and makes progress visible

• Enjoys working in a high trust, high ownership environment

Nice to have

• Fintech experience, or experience building software where correctness and auditability matter

• Experience using AI tools effectively in engineering workflows (prompting, evaluation habits, lightweight automation, agentic flows)

How we work

• Cross-functional, outcome-oriented teams

• Decisions happen close to the work, informed by direct user insight

• We combine product discovery and delivery as one team

• Success is defined by value created, not volume shipped
