Job description

Location: Dublin - Hybrid, 2 days onsite
Salary: Up to €70,000 + benefits

MCS Group is delighted to be partnering with a growing Dublin-based technology company as they continue to invest in their product and engineering team.

They are looking for a Senior Frontend Developer to join a small, collaborative engineering environment where you will be expected to take genuine technical ownership of frontend work from early-stage ideas through to production.

This is not a role for someone who simply wants to receive well-defined tickets and build them.

The team need someone who is comfortable being given a problem, understanding what is missing, shaping the solution with Product and Engineering, making technical decisions and driving the work through to delivery.

The Role

Senior Frontend Developer

Location: Dublin - Hybrid, 2 days onsite
Salary: Up to €70,000 + benefits

MCS Group is delighted to be partnering with a growing Dublin-based technology company as they continue to invest in their product and engineering team.

They are looking for a Senior Frontend Developer to join a small, collaborative engineering environment where you will be expected to take genuine technical ownership of frontend work from early-stage ideas through to production.

This is not a role for someone who simply wants to receive well-defined tickets and build them.

The team need someone who is comfortable being given a problem, understanding what is missing, shaping the solution with Product and Engineering, making technical decisions and driving the work through to delivery.

What You'll Be Doing

• Taking ownership of frontend features and projects from early requirements through to production
• Helping shape technical solutions rather than simply implementing predefined tickets
• Working directly with Product to clarify requirements, identify gaps and define how features should work
• Making frontend architectural and technical decisions
• Breaking larger problems into deliverable pieces of work
• Building and developing modern web applications
• Working across React, Vue and modern JavaScript
• Building new functionality while helping modernise existing applications
• Integrating frontend applications with backend APIs and services
• Investigating issues beyond the frontend when needed
• Occasionally making smaller backend changes where appropriate
• Contributing to code quality, maintainability and engineering standards
• Considering security and potential vulnerabilities when building new functionality
• Using modern AI development tools to improve productivity while retaining strong engineering judgement
• Working independently while collaborating closely with the wider product and engineering team

What We're Looking For

The biggest requirement for this role is proven senior-level technical ownership.

We are looking for someone who has already demonstrated that they can take responsibility for a meaningful piece of work without needing every requirement, task or solution to be fully defined for them.

You should have:

• 7-10 years of experience
• Strong commercial JavaScript experience
• Strong experience with React, Vue or another modern JavaScript framework
• Proven experience owning substantial frontend features or applications
• Experience taking loosely defined requirements and helping shape them into technical solutions
• Evidence of making technical or architectural decisions independently
• Experience working directly with Product, Design or other stakeholders
• Strong understanding of APIs and how frontend and backend systems interact
• Some backend exposure or a willingness to investigate and work outside the frontend when required
• Strong problem-solving skills and the confidence to challenge or improve an initial approach
• Good understanding of secure development practices
• Experience working autonomously within a product engineering environment
• Strong communication skills and the ability to work effectively across a small engineering team

You do not need formal people management or team leadership experience.

This role is about technical leadership and ownership, not managing a team.

You also do not need commercial experience with both React and Vue. Strong experience with one modern JavaScript framework and the ability to adapt is more important.

Nice to Have

• PHP backend experience
• Broader full-stack development experience
• SaaS or B2B product experience
• Experience within fintech, payments, identity, security or another regulated environment
• Experience in a startup, scale-up or smaller product engineering team
• Mentoring experience
• Portfolio, GitHub or examples of products you have helped take from idea through to production

What's On Offer

• Salary up to €70,000
• Hybrid working, typically 2 days onsite in Dublin
• Pension
• €400 annual wellbeing allowance
• Annual salary reviews
• Flexible working culture
• Regular workshops, hackathons and learning opportunities
• Opportunity to work within a small engineering team where your decisions genuinely influence the product
• Significant ownership over upcoming frontend projects

This is a strong opportunity for a genuinely senior frontend engineer who wants more than a ticket-driven development role.

You will be joining a team where you will be trusted to help shape solutions, make technical decisions and take meaningful frontend work from an initial idea through to production.
