Hire With Haven

Applause is a profitable, well-capitalized operator of consumer subscription apps across privacy, security, health, productivity, and accessibility. The model is simple: acquire high-retention, category-leading apps and scale them. The portfolio includes PicSafe, Nomorobo, Meditation Moments, Strongbox, and Voice Dream.

The apps already have top 1% retention, strong brands, and high organic traffic, so paid growth compounds on proven products instead of propping up weak ones. There is real budget behind growth that works.

The company has raised $100M+ across debt and equity and runs remote-first with ~40 people worldwide (roughly 40% US, 50% Europe, 10% elsewhere). It is now building its growth function from the ground up.

This is execution role in paid user acquisition. The primary mandate is to plan, launch, and optimize paid campaigns that drive installs and new subscription revenue across the portfolio — starting with one to two apps and expanding as you prove results.
 

Area of influence

• Run paid UA campaigns hands-on: owns profitable paid acquisition, starting with Meta and TikTok, then coordinating ASA and Google with existing owners.
• Own creative testing end to end: build the testing roadmap, brief and iterate on ad creatives, dissect what wins and why, and feed learnings back into the next cycle.
• Monitor performance daily in the MMP and ad platforms, catch anomalies early, and reallocate spend toward what pays back.
• Support the measurement setup: event configuration in the MMP, SKAN/postback hygiene, and web-versus-app attribution checks, so the numbers you optimize against are trustworthy.
• Bring your own experiment ideas — new channels, angles, and audiences — size them by expected payback, and run them without waiting for a task list.
• Report results and learnings in writing on a weekly cadence; the culture is writing-first and async.
   

Who are we looking for

• 3+ years of hands-on paid UA experience for consumer mobile apps, with subscription apps strongly preferred; you have personally managed meaningful budgets and owned the outcomes, not just watched dashboards.
• Working knowledge of the modern app-growth stack: an MMP (AppsFlyer, Adjust, or Singular), Amplitude or Mixpanel, and paywall/subscription tooling (Superwall, RevenueCat) — with opinions on the tradeoffs, not just tool names.
• Thinks in payback and cohorts rather than platform-reported ROAS; comfortable pulling their own data before making a call.
• Uses AI tools daily to move faster — reporting, creative iteration, analysis — and has current opinions on which ones actually help.
• Scrappy and independent: startup, indie, or small-team background rather than big-company process; figures things out without hand-holding.
   

Team & Background

You join at the ground floor of the growth function, working directly with the VP of Performance Marketing and alongside the senior growth hire as the team takes shape. Strong performers grow with the portfolio: more apps, more budget, more scope — Applause promotes people who are not bound by their job description. The path from specialist to senior operator (and eventually toward GM-level ownership of an app) is real and intended.
 

Comp. Competitive monthly base (USD) + performance bonuses tied to the growth you drive. Full-time engagement, structured as a contractor arrangement

Haven is helping Applause hire a Senior Full-Stack Engineer to lead web-to-app engineering across its portfolio of consumer subscription apps.

You will own the complete journey from landing page to app subscriber and build reusable infrastructure that can be scaled across multiple products.

Responsibilities

• Build and maintain landing pages, web onboarding, checkout flows, and web-to-app routing.
• Own backend endpoints, server-side events, and integrations with growth and analytics tools.
• Implement and troubleshoot RevenueCat, Superwall, Customer.io, MMP, and GA4 integrations.
• Ensure reliable attribution, event tracking, identity handoff, and subscription data across web and mobile.
• Build reusable components and implementation playbooks for the wider app portfolio.
• Partner with growth, product, mobile engineering, and data on funnel experiments and new launches.
• Diagnose and resolve checkout, tracking, routing, and attribution issues.
• Build lightweight dashboards or internal tools when needed, without owning the data warehouse.

Requirements

• Senior full-stack engineering experience with end-to-end ownership of production systems.
• Strong experience with Next.js or a comparable modern full-stack framework.
• Hands-on experience with backend endpoints, checkout or subscription flows, server-side tracking, and SDK integrations.
• Extensive experience building web-to-app funnels for mobile app growth.
• Working knowledge of RevenueCat, Superwall, Customer.io, MMPs, and GA4.
• Strong understanding of attribution and event flows across web and mobile.
• Ability to work autonomously and translate growth requirements into reliable technical solutions.

Nice to Have

• Consumer subscription app or DTC experience.
• Experience with paid acquisition funnels, experimentation, pricing, or paywall testing.
• Experience supporting multiple products or brands through shared infrastructure.
• Experience building lightweight operational dashboards.

Applause is a profitable, well-capitalized operator of consumer subscription apps across privacy, security, health, productivity, and accessibility. The model is simple: acquire high-retention, category-leading apps and scale them. 

The apps already have top 1% retention, strong brands, and high organic traffic, so paid growth compounds on proven products instead of propping up weak ones. There is real budget behind growth that works.

Area of influence

• You set up the growth function from scratch and own it end-to-end — the campaign infrastructure, the measurement layer, the reporting, and the playbooks that make paid growth repeatable across many apps. This is a builder-operator role: you're expected to build the systems, not just run the accounts.
• Stand up the measurement and reporting backbone yourself: pipelines from network and MMP APIs, internal dashboards, and budget/creative automations. Comfort in SQL and Python (or equivalent) to build this rather than wait on a data team is a core part of the job.
• Build and own trustworthy attribution across a multi-app portfolio: layered MMP-based setup with S2S/CAPI and event deduplication, probabilistic and network-native models (Meta AEM, TikTok Attribution Flex), with SKAN as one input among several — reconciled against your own backend numbers so the payback math holds up.
• Plan, launch, and optimize paid UA hands-on across Apple Search Ads, Google, Meta, TikTok, and paid web — owning budgets, bids, audiences, and creative testing against payback and CAC targets per app.
• Build and pressure-test your own cohorted LTV and payback models rather than trusting platform-reported ROAS — and use that predicted-LTV number as the gauge for budget and profitability decisions across every app.
• Drive organic acquisition in parallel with paid — ASO, store-listing conversion, and web-to-app / web-to-web flows — so the top of the funnel grows through every lever, not just paid spend.
• Generate the experiment roadmap independently: bring your own ideas for new channels, creative angles, and tests, size them by expected payback, and run them without waiting for a task list.
• Own secondary paywall and funnel optimization, and coordinate lifecycle (email/push) support — partnering with the lifecycle and analytics hires so monetization and retention keep pace with the traffic you drive.
• Report results, learnings, and forecasts to the CEO weekly, and brief app GMs on what's working, what isn't, and what you need from them to scale. Flat structure, direct communication, fast decisions.

Who are we looking for

• Has personally deployed meaningful paid spend at a consumer subscription company (on the order of $10M+/year, or smaller budgets run with real rigor), with direct ownership of the numbers and outcomes.
• Genuinely technical: builds their own reporting, attribution, and automation in SQL/Python — not just an operator of dashboards someone else maintains. Has stood up API pipelines and rules-based ad-management automations before.
• Deep, hands-on fluency with the modern app-growth stack — an MMP (AppsFlyer, Adjust, or Singular), a product-analytics tool (Amplitude/Mixpanel), paywall/funnel tooling, and lifecycle (Customer.io or similar) — or has built the equivalent in-house, with strong, specific opinions on which tools to use and why.
• Modern about measurement: comfortable with probabilistic and network-native attribution, SKAN-aware, and runs real incrementality checks. Builds and pressure-tests LTV and payback models rather than taking platform ROAS at face value.
• Has operated across multiple apps or product lines at once and can context-switch across a broad portfolio (three to seven-plus apps) without letting performance slip.
• Thinks in unit economics and profitability thresholds, works well in a flat, communicative team, and is proactive — brings the roadmap rather than waiting for one.

Team & Background

A genuine player-coach: expected to execute campaigns directly today, with a clear path to hire and lead a small growth team as the portfolio scales.

Knows exactly what to keep in-house versus outsource, and can name the first few hires and vendors they would line up for each function.

Background skews scrappy and operator-heavy rather than corporate: founders, early-stage operators, and people who have built a growth function from zero
