Senior Graphic Designer

Job Title: Senior Graphic Designer
Location: Mumbai
Company: Big Brainco
Employment Type: Full-time

About Big Brainco

Big Brainco is a dynamic digital agency focused on helping brands and content creators enhance their online presence through innovative strategies, content creation, and data-driven insights. We work with diverse clients across industries to develop and execute impactful social media campaigns.

Role overview

The Senior Graphic Designer works across all client accounts at BigBrainco, owning the agency's most demanding and high-visibility design work while continuing to deliver the full range of visual assets - YouTube thumbnails, Instagram creatives and carousels, brand kits, social media templates, and motion graphics. This role carries greater creative autonomy than a standard Graphic Designer position and includes reviewing junior designers' work, contributing to design systems and workflow improvements, and collaborating with the video/production team. This is a growth-track role, with the Senior Graphic Designer expected to eventually lead the Graphic Design team.

Key responsibilities

YouTube Thumbnail Design
Design high-quality, click-worthy YouTube thumbnails for all client channels - visually bold, brand-consistent, and optimised to drive CTR.
Deliver thumbnails ahead of every scheduled upload, without exception.

Instagram Creatives & Carousel Design

Create engaging Instagram static creatives and carousel posts across all client accounts.
Maintain platform best practices, visual hierarchy, and brand identity throughout every creative.

Brand Kits & Style Guides

Develop and maintain comprehensive brand kits and style guides for each client - covering typography, colour palettes, logo usage, and design language.
Keep brand kits updated promptly whenever client guidelines change, and use them as the single reference point for all visual output.

Social Media Templates

Design reusable, editable templates for recurring content formats across client accounts.
Build templates that enable faster turnarounds and consistent visual output across the wider team.

Brand Consistency & Design Quality

Ensure all design output, across every client and every format, maintains a consistently high standard of visual quality.
Proactively flag when a client's brand kit is outdated or inconsistent, rather than designing around it.

Junior Designer Mentorship & Quality Review

Review work produced by junior/associate designers and provide constructive, actionable feedback before it reaches the Creative Head.
Support the onboarding and skill development of newer designers on tools, brand systems, and design standards.

Complex & High-Priority Account Ownership

Take ownership of the agency's most demanding, high-visibility client accounts.
Apply advanced design judgment to solve complex creative challenges that go beyond standard briefs.
Design Process, Systems & Workflow Improvement
Contribute to design SOPs, file management systems, and workflows that improve consistency and speed across the team.
Help build the foundation for eventually leading the Graphic Design team.

Cross-Functional Creative & Motion Collaboration

Collaborate with the video editing and production teams on projects requiring crossover between static design and motion/video work.
Ensure visual and narrative consistency across formats.

What we're looking for

Experience & Background
4–6 years of experience as a Graphic Designer, with agency experience strongly preferred.
A strong portfolio demonstrating YouTube thumbnails, social media creatives, brand identity work, and motion graphics.
Experience building and maintaining brand kits or style guides across multiple clients or brands.
Prior experience reviewing or mentoring junior designers, or clear readiness to take on that responsibility.

Skills & competencies

Strong proficiency in Adobe Photoshop and Illustrator.
Working knowledge of Adobe Premiere Pro is a strong plus.
Strong understanding of platform-specific design requirements for Instagram and YouTube.
Ability to design for CTR and visual impact, not just aesthetics.
Advanced design judgment - able to independently solve complex creative briefs with minimal oversight.
Ability to give clear, constructive design feedback to junior team members.
Sharp eye for typography, colour theory, layout, and visual hierarchy.
WHY BIGBRAINCO?
Own the agency's most complex and high-visibility design work from day one.
Direct growth path toward leading the Graphic Design team.
Build a portfolio spanning thumbnails, social creatives, brand systems, motion design, and team mentorship.
Collaborative, creative, and high-energy work culture.
