Subcontractor Opportunity: Senior Go + React Developer - Help Launch a New SaaS Product

Senior Go + React Developer - Subcontractor Opportunity

Were looking for an experienced Senior Go + React developer to support the final delivery and internal launch of a well-advanced SaaS platform.

This is a subcontractor opportunity for someone who can step into an existing product, understand the architecture quickly, make sound technical decisions, and help ship focused, commercially useful outcomes.

The product is already in active development and close to internal rollout. Were looking for a senior contributor who enjoys practical delivery, clear priorities, and meaningful product impact without unnecessary process or over-engineering.

The role

Youll work across the backend and frontend of an existing SaaS product, helping strengthen key workflows, complete final-stage implementation, and prepare the platform for internal use.

This is not a rebuild and not a permanent employee position. It is a focused subcontractor engagement suited to a senior developer who values autonomy, direct access to decision-makers, and the ability to contribute quickly.

Tech stack

Core requirements:

• Go / Golang
• React
• Full-stack SaaS product development experience

Bonus:

• React Native experience

React Native experience is helpful, but not essential. Strong Go and React capability is the priority.

What youll work on

Youll help with practical, delivery-focused work such as:

• Completing backend and frontend implementation for key product areas
• Strengthening organisation-based user workflows
• Improving onboarding flows for organisations and users
• Refining permissions, access control, and data handling
• Resolving issues that affect rollout readiness
• Stabilising important workflows for internal launch
• Working with the existing team to make clear, pragmatic implementation decisions
• Keeping the codebase clean, maintainable, and commercially fit for purpose

Why this opportunity is attractive

This role is well suited to a senior subcontractor who wants meaningful product work, clear priorities, and direct impact.

Youll be joining a real SaaS product at an important stage, where your contribution will have visible influence on how the platform is launched, used, and improved.

You can expect:

• A well-advanced product with clear delivery priorities
• A flexible subcontractor arrangement
• Practical scope and direct contribution
• Close access to founders and decision-makers
• Minimal bureaucracy and focused communication
• Opportunity for ongoing work as the platform grows
• A role where senior judgment matters

Were looking for someone who has

• Strong experience building with Go / Golang
• Strong experience building modern React applications
• Full-stack product development experience
• Confidence working in an existing codebase
• Strong debugging and problem-solving ability
• Practical technical judgment
• The ability to prioritise useful delivery over unnecessary rewrites
• Clear communication and reliable follow-through
• Availability to commit to an agreed subcontractor engagement

Youll be a strong fit if you

• Enjoy stepping into existing products and making them stronger
• Can quickly understand architecture, priorities, and trade-offs
• Are comfortable working with founders, product owners, or small delivery teams
• Prefer practical, maintainable solutions over theoretical perfection
• Can work independently while keeping communication clear
• Like shipping outcomes that matter to the business and its users

Engagement type

This is a senior subcontractor opportunity with flexible engagement terms to be agreed based on availability, scope, and delivery needs.

It is best suited to an experienced developer who can contribute with autonomy, make sound technical decisions, and support the product through internal launch readiness and beyond.
