MEAN Stack Lead

Full Stack Support Engineer

Node.js, React & Production Application Support

📍 Remote | Full-time | Night Shift | 3+ Years

About the Role

Unico Connect is an AI-first technology partner that builds custom mobile, web, and AI products for clients across multiple geographies.

We are hiring a Full Stack Support Engineer who will own day-to-day application support for a live customer product built on Node.js and React, working a fixed night shift aligned to North American business hours.

The mandatory requirements for this role are prior professional experience working a night shift, and the willingness to continue working a permanent night shift, Monday through Friday, approximately 7:00 PM to 4:30 AM IST, with on-call support coverage on weekends.

The role is fully remote.

The work is hands-on across the stack: triaging issues from monitoring alerts and customer tickets, performing root cause analysis, shipping bug fixes, applying minor framework and library updates, and communicating with the customer directly during the shift.

When there is no active support work, the engineer will contribute to other development projects within the company, so consistent productive output across the shift is expected.

Responsibilities:

Incident Response and SLA Adherence

Acknowledge and act on alerts and customer-raised tickets within the SLA window.

Critical incidents require response within 1 hour and best-effort resolution within 2 to 4 hours.

P1 issues require response within 2 to 4 hours and resolution within 1 business day.

P2 and P3 issues follow the documented SLA matrix.

Bug Fixes and Production Support

Investigate and resolve defects in previously built functionality across the customer-facing portal, internal portal, backend services, and third-party integrations.

Write clean fixes with appropriate tests and documentation.

Monitoring and Proactive Triage

Operate the application and infrastructure monitoring stack.

Investigate anomalies before they become incidents.

Tune alerts to reduce noise and improve signal.

Customer Communication During the Shift

Communicate directly with the customer in English during incidents and routine support, in writing and on calls.

Set clear expectations on status, root cause, and timeline.

Close the loop after resolution.

Minor Framework and Dependency Updates

Apply minor version upgrades to operating systems, frameworks, and libraries to maintain compatibility and security.

Test rigorously before promoting to production.

Hands-On Development Across the Stack

Work in the existing Node.js (Express, NestJS) backend and React frontend codebase.

Make focused changes that respect the existing architecture and patterns.

Contribution to Other Development Projects

When the support workload is light, contribute to other active development projects within Unico Connect.

Pick up well-scoped tasks, ship them to the team’s quality standard, and remain available to drop back into support work as soon as it is needed.

Root Cause Analysis and Write-Ups

For every meaningful incident, document the cause, the fix, the customer impact, and any follow-up actions to prevent recurrence.

Weekend On-Call Coverage

Provide on-call support coverage on weekends.

Respond to alerts and customer tickets within the defined SLA window.

AI-Assisted Support Workflows

Use Claude, Cursor, and similar tools day to day for triage, log analysis, code reading, and patch drafting.

Apply judgment on when to trust AI-generated output and when to verify.

Handover Discipline

Maintain clean shift handover notes for the day-shift team.

Track open issues, in-progress investigations, and customer commitments so nothing drops between shifts.

Requirements:

Prior Professional Night-Shift Experience (Mandatory)

Candidates must have worked a permanent night shift in a prior professional role for a meaningful period of time.

Adjacent late-evening shifts or occasional on-call do not qualify.

Willingness to Work a Permanent Night Shift Aligned to North American Business Hours, with On-Call Support Coverage on Weekends (Mandatory)

The shift is Monday to Friday, approximately 7:00 PM to 4:30 AM IST.

Candidates who cannot commit to night-shift hours on an ongoing basis should not apply.

3+ Years of Professional Full Stack Engineering Experience

With hands-on production work in both Node.js and React.

Strong JavaScript and TypeScript Proficiency

With React on the frontend and Node.js (Express, NestJS) on the backend.

API design experience with REST.

Comfortable reading and modifying an existing production codebase without breaking adjacent functionality.

Production Debugging and Incident Response Instincts

Ability to read logs, traces, and metrics to isolate a problem quickly.

Comfort triaging across application code, database queries, third-party API failures, and infrastructure.

Working Experience with Relational Databases

(PostgreSQL or MySQL), including reading and writing SQL, basic schema understanding, and the ability to investigate data-related incidents.

Familiarity with Cloud Infrastructure

On AWS, GCP, or Azure, at the level of reading logs, restarting services, deploying through CI/CD pipelines, and basic operational tasks.

Working Knowledge of Git, CI/CD Pipelines, and Monitoring Tools

At least one monitoring or observability tool (Datadog, New Relic, Sentry, CloudWatch, Grafana, or equivalent).

Strong Written and Spoken English Communication

This role involves direct customer interaction during the shift.

Calm, clear, professional communication in writing and on calls is non-negotiable.

Bachelor’s Degree

Bachelor’s degree in Computer Science, Information Technology, or a related engineering discipline.

Exceptional candidates with demonstrable production experience and strong portfolios may be considered without a formal degree.

Alertness, Judgment, and Ownership Mindset

Night-shift support work demands self-direction, attention to detail under low-supervision conditions, and the discipline to follow process when fatigued.

Nice to Have

• Prior experience in application support, AMC, or managed services engagements
• On-call experience with documented SLAs
• Experience with feature flag tools, error tracking platforms, or APM dashboards
• Exposure to AI-assisted development tools in a support context

About the Role

We’re looking for a Full Stack Developer who deeply cares about how things look, feel, and flow. Someone who writes elegant code and designs beautiful, functional experiences that users love.

You’ll work at the intersection of design and engineering, turning ideas and prototypes into smooth, high-performing applications built on React and Node.js. This role suits developers who think in pixels, obsess over transitions, and genuinely want every click and animation to feel just right.

Responsibilities

• Develop modern, responsive interfaces using React.js, TypeScript, and UI frameworks (Tailwind, Material, or similar).
• Transform design mockups and Figma prototypes into production-quality web experiences.
• Build scalable APIs and backend systems using Node.js, Express.js, and REST/GraphQL.

• Collaborate with designers and product teams to refine visual and interaction details.
• Deploy, monitor, and scale applications on AWS (EC2, S3, CloudFront, Lambda, RDS).
• Maintain high code quality through clean architecture, testing, and peer reviews.

You’ll Fit Right In If You

• Love crafting beautiful, consistent, and intuitive interfaces.
• Notice when a button is off by a few pixels and care enough to fix it.
• Balance creativity with engineering discipline.
• Enjoy solving real user problems with thoughtful design and seamless performance.
• Have opinions about UX — and back them with reasoning, not ego.

Tech Stack

• Frontend: React.js, TypeScript, Redux / Zustand, Tailwind CSS, Styled Components
• Backend: Node.js, Express.js / NestJS, RESTful APIs, GraphQL
• Databases: MySQL, MongoDB, PostgreSQL (optional), Redis (caching)
• Cloud & Tools: AWS (EC2, S3, CloudFront, RDS, Lambda), Docker, CI/CD, GitHub Actions
• Bonus: Next.js, Figma-to-code workflows, WebSockets, Serverless functions

Qualifications

• 3–7 years of full-stack experience with a strong frontend/UI focus.
• Proven experience creating visually stunning and user-centered web apps.
• Deep understanding of frontend architecture, design systems, and responsive layouts.
• Solid knowledge of databases, API design, and deployment best practices.
• Bachelor’s degree in Computer Science or equivalent practical experience.

Why Join Us

• Build products that users actually love to use.
• Collaborate with a design-first, detail-oriented team.
• Work with modern tech and creative freedom.
• Shape the product’s visual identity and user experience end-to-end.
