About The Role
As Business Solution Lead, you're the senior operator who turns complex brand problems into Ripples solutions — and then closes them. Reporting directly to the CCO with no team beneath you, you're deliberately a solo seat: we rebuild the bundle for every client we win, and the scoping, pricing, and pitch are senior work that doesn't scale by adding juniors.
You'll work the CCO's named account list and the deals that come in through senior channels — brands that need to buy an
end-to-end solution across our seven service lines (Commercial Live, Fulfillment, Affiliate, Shop Management, KOL, Video
Production, and — selectively — Marketing), not a point service. You'll partner with delivery leads to build the right mix (not
the biggest one), price it, prove we can staff it at margin, pitch it to brand leadership, and hand delivery to the cluster manager
at signature. The commercial relationship stays with you — for the next deal, and the next.
Your five-step mandate:
1. Target — Work the CCO's named account list and meet existing clients to find the next service line.
2. Solution — Build the bundle with delivery leads across our seven service lines. Right mix, not biggest mix.
3. Feasibility — Price the package. Prove we can staff it and deliver at margin.
4. Pitch — Present to brand leadership and close the commercial terms.
5. Hand over — Cluster manager takes delivery at signature. The commercial relationship stays here, for the next
deal.
Key Responsibilities
1. Win new clients — solutioning, then the pitch
• Turn a brand's problem into a Ripples bundle — scoped across seven service lines and made real by pulling in the
right delivery leads early.
• Work the accounts the CCO names — the deals we decide to go after, not only the ones that come in.
• Present to the brand's senior leadership and close the commercial terms.
• You own new-business PC1.
2. Grow the clients we have — upsell and cross-sell
• Sit with existing clients and their cluster manager to find the next service line, then scope and close it.
• Keep the commercial relationship after the cluster takes delivery, so there is always someone whose job is the next
deal.
• You own the client relationship.
3. Prove we can deliver it — package feasibility
• Price the package, confirm we can staff it, and model the margin before anything is promised.
• Say no — to a bad-fit brief, an unbuildable scope, or a price that only works on paper.
• You own what we promise.
Qualifications
Must-have — no offer without these
• Consulting mind: 5+ years with a management consulting skillsets — or the same structured problem-solving
muscle built elsewhere.
• Commerce fluency: Background in commercial, retail, or e-commerce. People from the sector pick up seven
service lines far faster.
• Client-facing: You've sold and presented to senior client stakeholders, and can hold the room without being carried.
• Numbers: You build and defend a feasibility model. You read a P&L. You aren't talked out of the maths.
• Agile: Small team, no support layer. You go the extra mile because the job needs it — not because someone asked.
Strongly wanted — the tie-breakers
• AI fluency is a baseline expectation, not a bonus. You actively use AI tools (ChatGPT, Claude, image/video generators, analytics co-pilots, automation tools) in daily work —research, modelling, deck-building — as your
default, not a claim.
• Language: Fluent English is required. Chinese or Korean is a real plus for the brands we're chasing.
• Range: You move between a founder conversation, a delivery lead's staffing plan, and a pricing model in the same
day.
• Judgement: Willing to say no to a bad-fit brief — including one that came from the top.
How We'll Assess You
Four steps. We test the work, not the CV.
1. Scoping case — We give you a real brand brief. You build the bundle and defend why those service lines and not
the others.
2. Feasibility — You price it, staff it, and show the margin. We push on the assumptions.
3. Pitch — You present the solution to a panel, as you would to the client.
4. AI demonstration — You show how you used AI to get there — the tools and the thinking, not a claim.
Red flag: A relationship-only seller who needs someone else to build the scope. This isn't that seat.
What You'll Get
• Direct report to the CCO — one of seven at that layer — with a mandate to build a brand-new function that shapes
how Ripples wins the next tier of business.
• End-to-end ownership of the deals that matter most: from scoping to signature to onboarding, across seven service
lines and some of Thailand's most complex brand engagements — global sportswear, consumer electronics,
dermatology beauty, and FMCG.
• New-business PC1 target set at appointment— a clear number, a direct line of sight to impact.
• Work at the leading edge of AI-powered commerce — building ways of working that most agencies haven't
figured out yet.
• Fast-track your career in a hyper-growth commerce company (20 → 200+ in two years).
Who This Role Is For
We're hiring across two levels in this track. Apply once — we'll calibrate during the interview.
- Account Manager (3–5 yrs) — You own a client brand portfolio end-to-end as an individual contributor. You think like a brand strategist and execute like a commerce operator.
- Senior Account Manager (5–8 yrs) — You own larger or more strategic brand portfolios, manage 1–2 indirect reports, and sit shoulder-to-shoulder with the Account Director on planning, growth, and client leadership.
About The Role
As Account Manager / Senior Account Manager, you'll own the brand, marketing, and
commercial growth of an assigned client portfolio — translating brand strategy into executable plans across TikTok Shop, Shopee, Lazada, and beyond. You'll partner closely with client brand teams, internal Ripples functions (IMC, media, livestream production, creative, operations, fulfillment), and the Account Director.
This is a hybrid role: part senior client partner, part brand strategist, part commercial operator.
At the SAM level, you'll also start growing the next generation of the team.
Key Responsibilities
• End-to-End Brand Ownership: Own the brand strategy, GTM, and commercial performance
of an assigned client portfolio. Translate client objectives into integrated plans that drive
sales, share, and brand health.
• Client Partnership: Serve as the primary day-to-day partner for the client — lead business
reviews, planning sessions, and performance discussions. Build trust as a strategic advisor,
not just an executor.
• Marketing Campaigns & GTM: Plan and execute integrated 360 campaigns across product launches, hero SKU activations, and seasonal moments. Lead go-to-market from concept through post-launch review.
• Social Commerce Strategy & Execution: Direct the livestream, affiliate, short-video, and
creator playbooks for the brand. You're accountable for the calendars, the outcomes, and the next experiment to try.
• E-commerce & Retail Activation: Drive growth across TikTok Shop, Shopee, Lazada, and DTC; build the playbook for entry into modern trade and premium retail when the brand is ready. Own merchandising, promo calendars, and channel-level performance.
• Performance & Insights: Monitor sales, campaign performance, traffic, conversion, and platform KPIs. Translate insights into clear next plays — landed in decision-ready reports for the Account Director and client.
• Commercial Growth: Drive account growth through upselling, cross-selling, and identifying new opportunities. Support commercial negotiations, budgeting, and forecasting alongside the Account Director.
• Cross-Functional Orchestration: Quarterback Ripples' delivery engine for your portfolio — IMC, media, livestream production, creative, operations, fulfillment — to execute campaigns on-brand, on-time, and on-target.
• (SAM only) Team Leadership & Talent Development: Lead, coach, and grow 1–2 indirect reports. Set clear KPIs and expectations, give feedback that compounds, and build a culture of ownership and learning.
Qualifications
• Account Manager: 3–5 years of experience in account management, brand management,
marketing, e-commerce, or trade marketing.
• Senior Account Manager: 5–8 years of experience, including hands-on people leadership or substantive mentoring of juniors.
• Proven track record growing brands on TikTok Shop, Shopee, and Lazada, with hands-on experience across livestream, affiliates, short video, and creator/KOL programs — you understand how the social commerce flywheel actually spins.
• Strong commercial mindset — you can read a P&L, drive negotiations, and find the next
pocket of growth.
• Excellent client communication, presentation, and stakeholder management — you can hold the room with senior client partners.
• Data-focused with strong analytical and problem-solving skills; advanced Excel / Google Sheets and confidence with platform analytics.
• AI fluency is a baseline expectation, not a bonus. You actively use AI tools (ChatGPT,
Claude, image/video generators, analytics co-pilots, automation tools) to scale output,
sharpen decisions, and unlock leverage across your work and team.
• Working-level English to partner with global brand clients and regional stakeholders.
• Bachelor's degree in Marketing, Business Administration, Communication Arts, or related fields.
