AiTou · Columbia Startup Lab

Designing a job referral platform from 0 to 1

A new feature for an early-stage job-seeking platform helping international students find roles with visa support. Built end-to-end as Product Design Lead - research, design, and a fresh design system.

AiTou job referral platform overview
Background
AiTou is a job-seeking platform incubated at Columbia Startup Lab, helping international students find roles with visa & sponsorship support. At fund-raising stage, the team needed a way to grow users and unlock monetization.
My Role
Product Design Lead. Worked with the founder, engineers, and PM. Owned competitive analysis, product strategy, user research, UX/UI design, and the design system end-to-end.

Context

Why job referral?

We saw a huge unmet need for job referrals in the market. Beyond the user demand, referrals also opened up more monetization paths than pure job-search ever could - sponsored posts, premium referrer tools, paid match acceleration.

For AiTou, this wasn't a feature - it was a product pivot.

Problem Definition

Job referral is messy - for both sides

I empathized with users by interviewing 9 job-seekers and 8 referrers to surface pain points across the existing referral flow.

Job-seeker persona
Job-seekers

Usually look for referrals on LinkedIn by connecting with others or reach out to friends who already work there. The connecting and back-and-forth messages is time-consuming. It is also hard to track their requests or get responses timely.

Referrer persona
Referrers

Most referrers said that it is difficult to find suitable candidates, they don't know where to post the referral information, and it is hard to manage all the requests via emails.

User Personas

Who I designed for

Two distinct sides of the marketplace, each with their own jobs-to-be-done. The platform had to serve both - or it served neither.

Ideation

Building bridges - redefining job referrals for both sides

We wanted to design a platform that lets job-seekers find matching referrals & request them (no more back-and-forth, no more wondering if anyone got the message), and lets referrers post referral info & manage requests easily (one place to find candidates, one place to respond).

Two-sided platform concept

Two sides, one platform - the design has to keep both moving

Solution Preview

A platform that matches seekers with referrals - and helps referrers manage requests

Two coordinated flows: job-seekers browse referrals, request, and track status; referrers register, build a profile, post referrals, and manage incoming requests. Below is a walkthrough of each side, plus the design process I followed to get there.

For Job-seekers

Fill in a referral request, submit it directly to the referrer's inbox, then track or withdraw the request from the profile page.

Design Process

The flow I followed to ship this MVP - testing fed back into prototyping rather than waiting for one final review at the end.

Design process - Research, Ideation, Prototype, Testing, Implement

Research → Ideation → Prototype → Testing → Implement (with a feedback loop back to Prototype)

Competitive Analysis

How are other platforms doing job referral?

Before designing, I researched the landscape. Few platforms focus mainly on job referrals; the closest patterns came from Exponent and 1point3acres. I broke down each model's pros and cons to find where AiTou could differentiate.

Exponent · Anonymous request

Job-seekers submit referral requests blindly; they don't see referrer info or profiles. Referrers reach out if interested.

Exponent referral flow
Pros
Referrer info is perfectly protected. Flow is straightforward and easy to build.
Cons
Job-seekers know nothing about the referral or potential referrers. Referrers can't customize requirements.

1point3acres · Public referral posts

Referrers post referral details on the platform to recruit candidates. Job-seekers browse posts and reach out to referrers directly.

1point3acres referral flow
Pros
Referrers can customize requirements. Job-seekers know the referral info better before reaching out.
Cons
No way to verify referrer credibility. Hard for referrers to manage all the requests. Job-seekers must browse for a long time to find suitable posts.
Define MVP

Defining and building an MVP that matters

After identifying key gaps and opportunities in the market, we brainstormed ideas, prioritized features, and defined a focused MVP to address the most critical needs - protecting both sides' time and privacy without bloating scope.

User Flow

Mapping the user journey

Two flows, two distinct mental models. The job-seeker flow optimizes for finding and requesting; the referrer flow optimizes for posting and managing. Each side's pain points became checkpoints in the diagram.

Usability Testing - Job-seekers

Two rounds with real seekers

Recruiting

Method - Think Aloud

Participants shared their screen (if remote) and thought aloud through the whole process. I recorded the screen and verbal answers, then walked them through three tasks:

Think Aloud method - sticky notes plan

Think Aloud - planning prompts and follow-up questions per page

1st round - 5 in-person participants

2nd round - 17 participants total

Each team member found 2-3 target users. We sent out a survey to gather quantitative feedback to balance the qualitative observations from round 1.

Key Feature Iteration - Job-seekers

What changed after testing

Browse Referrals

Users couldn't tell which referrals were active vs. expired and missed the filter affordance. I rebuilt the list with status pills, clearer hierarchy, and a persistent filter rail.

Referral Card

What information should appear in the card before a click? Testing showed seekers wanted role, location, deadline, and referrer's seniority - not the referrer's name. Cards became scannable instead of dense.

Referral Details

The detail page balanced two competing needs: giving seekers enough context to decide, and protecting referrer privacy. I added an explicit "what referrers will see" section so seekers self-edit before sending.

Referral Details - before and after iteration
Usability Testing - Referrers

Five remote sessions with active referrers

AiTou's existing referrer list became my recruitment pool. I ran 5 remote sessions where referrers screen-shared and thought aloud while posting a referral and managing incoming requests.

Key Feature Iteration - Referrers

What changed for the referrer side

Post Referrals

Referrers found the original post flow long and unclear about what was required vs. optional. I split the flow into focused steps, surfaced "required" cues up front, and added a preview before publish.

Post Referrals - before and after iteration
Privacy Concern

Referrers worried about exposing their email or phone. I added a "what's visible to seekers" toggle on every step and routed all communication through the platform until the referrer opts in.

Privacy concern - before and after iteration
Design System

A new system for the rebrand

Alongside the new flows, I built AiTou's first formal design system to support a parallel rebrand - typography, color, components, and motion. The system gave the engineering team a stable foundation to ship the MVP fast and a clear path to extend later.

Key Takeaways

Job referral is deceptively simple - the work is in the seams

Job referral has a clean surface and a messy underside: company referral policies, referrer time scarcity, candidate privacy, request volume management. As the sole designer for 4 months, I had to hold all of it in my head simultaneously, develop the solutions, and sort out priority and feasibility on my own.

The experience also taught me how to deliver clean handoff to developers. My previous experience with HTML, CSS & JavaScript helped me communicate with engineers in their language - and made the trade-off conversations move much faster.

The biggest design lesson: in a two-sided marketplace, protecting one side's experience usually costs the other side something. The job is to find the trades that both sides quietly accept - and design the friction so each side feels respected, not blocked.
