Leading designers · SplitPay, 2024–26

Soft skills are the hard part.

Two stories from SplitPay. One about disagreeing with a designer I was coaching. One about coaching a designer who found it hard to push back.

My roleUX Lead

NamesLeft out on purpose

I lead as a service.

My job is to make my designers' lives easier. I take the tedious meetings with business partners. I help them find assets and connect with peers. If I can guide them, or clear something out of the way so their design work goes better, that's a win.

I lead from the background.

I want my designers to shine, so I tell them to take the credit. They rarely listen. They thank me anyway, because I'm a resource for them: solutions, ideas, working sessions.

Story 01 · Disagreeing well

One form, or one step at a time?

Setting up SplitPay as the main account holder.

  • The disagreement

    A designer on my team believed fewer clicks meant a better experience, so they wanted the enrollment flow to be one form. I believed in bite-size steps: one decision per screen, so nobody gets overloaded.

  • It got tense

    We're friends, but on this project I was their lead. I worked hard to keep those two things separate.

  • What I did

    I didn't argue opinion against opinion. I brought data. On FastPay, an earlier project, our usability test showed people digest progressive disclosure more easily. That was close enough to this problem that I trusted it. I showed them, then wireframed the flow my way so they could see it, not just hear about it.

  • What we didn't test

    We never tested the form approach. Sometimes you know what will win because you've seen almost the same problem before. I still owed them the evidence, so I put the FastPay result in front of them.

  • What happened

    They tested my version themselves, and the feedback was good. They bought in. One decision per step shipped, and it's still the flow today.

  • What I'd do differently

    Once I'd shown the data and the draft, I could have said it plainly: this is what we need to do, and here's why. I got there. I just took longer than I needed to.

What I took from itBe ready to back up what you've learned with data. I ask my designers to do that, so I have to do it first. Stay open, but hold the line when you know what you know.

Story 02 · Coaching

Holding the line without taking the pen.

A designer who kept giving in to partner asks.

  • The pattern

    Partners send small layout changes day after day. There's a saying for it: “everyone is a designer.” A designer on my team liked to keep people happy, so they kept saying yes.

  • The cost

    One or two of those asks are fine. But these broke our standards, accessibility, and basic good UI practice, and nothing in the research backed them. The result was rework.

  • One-on-one

    The message was simple. Bring data. Be the person in the room who knows what good design practice looks like.

  • Show, don't tell

    I brought them into a few of those meetings and held my ground with the partner myself, so they could watch how it's done.

  • Then I stepped back

    I'd offer an opinion or two so they didn't feel lost, but I let them win or lose on their own.

  • What changed

    They got better, though not as much as I hoped.

What I took from itCoaching isn't fixing. You can model it, hand over the tools, and get out of the way. The rest is up to the person.

In their words

What the people I worked with say.

From designers I led, a partner, and a director who managed me. Taken from their LinkedIn recommendations.

  • Designers I led

    “…he has always guided me and supported me in every idea I had. He’s not only an amazing designer but a great mentor too… The best thing about Marcos is, he is always doing the right thing for customers while keeping business in mind.”

    Sumit Mandal · UX Designer, AT&T · reported to me, 2022

    “He is a great leader and mentor. He is always available to help out with our brainstorming solutions.”

    Nina Corpuz · Senior Product Designer · reported to me, 2023
  • What I owned

    “Marcos and I worked on building multiple payments experiences from scratch over a tenure of 3 years… a major contributor in driving key metrics up for fast pay and AT&T internet air specifically.”

    Jasleen Kaur · Product, Braintree · same team, 2024
  • Partners

    “He has a strong understanding of best practices, a good eye for detail, and the patience to work with many stakeholders at one time.”

    Maggie McClellan · Principal Content Strategist, AT&T · same team, 2021
  • A director who managed me

    “He works well with others, continuously seeking improvement in his skills and the first to step up to help solve challenging problems or address last minute “fire drills” with no complaints.”

    Karla Radle · Director, User Experience · managed me directly, 2020
Underneath both stories

What runs every week.

The routines I ran with both designers on SplitPay.

  • Daily working sessions

    Time with each designer every day, working through the flows together.

  • Critiques and peer reviews

    Raising the bar through critique, not by redrawing their work.

  • Design Standards reviews

    Quality and standards held up at handoff, without me gatekeeping the work.

  • Go / no-go

    I gave the design green light, and I own the call and the outcome.

Bottom line

Make their work easier.
Let them shine. Get out of the way.
