Overview
Unico Connect is seeking a Senior Full Stack Engineer to architect and ship complex client features end-to-end. The role spans frontend architecture, backend system design, multi-database ownership, and the mentorship that scales the engineering practice. The position is well suited to senior engineers who can balance performance, type-safety, observability, and shipping velocity at production scale.
Key Responsibilities
- Architect and ship complex full-stack initiatives end-to-end
- Lead technical scoping with Product Managers and the Tech Lead
- Mentor 2-3 junior full-stack engineers through code reviews, design reviews, and 1:1s
- Drive performance optimisation across frontend (Core Web Vitals) and backend (P95 latency)
- Own production incidents and post-mortems; build resilience patterns
- Set frontend and backend standards including testing, observability, security, and type-safety
- Partner with DevOps on deployment, scaling, and on-call practices
- Lead architecture conversations for owned products including ADRs and design reviews
- Govern security posture for owned services including OWASP and SAST tooling
- Calibrate the full-stack interview bar and conduct senior interview loops
- Author internal full-stack playbooks and onboarding documentation
Required Qualifications
- 5+ years of full-stack engineering with at least 2 in a senior role
- Deep React and Next.js (App Router, server components, streaming)
- Strong Node.js with TypeScript or Python; production patterns ideally in both
- Multi-database experience (PostgreSQL, MySQL, MongoDB)
- Hands-on with Vercel, GCP, or AWS deployments at production scale
- Excellent code review, mentorship, and written communication skills
- Track record of owning at least 1 product at production scale (multi-tenant, high QPS, or regulated)
- Experience leading architecture decisions across both frontend and backend
- Capacity to balance product, performance, and engineering trade-offs
- Bachelor's degree in Computer Science, Engineering, or a related field
Preferred Qualifications
- Edge functions and server-side streaming experience
- Real-time features (WebSockets, WebRTC, Server-Sent Events)
- Web Workers, service workers, and PWA experience
- Open-source contributions or technical writing
- Conference talks
AI Tools Proficiency
Production engineering at Unico Connect assumes AI tools form part of the daily workflow rather than an experimental augmentation. For this role specifically:
- Claude Code or Cursor as the default integrated development environment
- v0 or Bolt for rapid frontend prototyping
- AI-assisted refactoring and code review tooling
- Perplexity for technical research during architecture decisions
What we look for at Unico Connect
Every Unico role expects the same underlying traits — regardless of department or seniority. If these resonate, apply.
Fluent with Claude, ChatGPT, Cursor, Figma AI, or whatever is relevant to your craft. We expect AI tools in the loop, not as a novelty.
Fast cycles, real ownership, low ceremony. You will not be a cog.
Output and outcomes matter more than process. You ship work that moves a metric.
You treat the codebase, the deliverable, and the client relationship as your own.
You joined because you want to ship amazing tech products, not warm a seat.
