ABOUT US

Amplify is one of the most established bundle and upsell apps on the Shopify App Store. Thousands of merchants use our product to grow revenue through bundles, upsells, and cross-sells.

We're a profitable, fully remote startup with a lean, experienced team and very little organizational overhead.

We're looking for a Lead Engineer to take ownership of our technical direction and help shape how we build software for the next stage of the company.

Remote across Europe. This role is fully remote and open to candidates currently living in Europe.

THE ROLE

You'll be the senior technical authority at Amplify.

You'll own architecture and major engineering decisions, stay hands-on with the code, lead the development team, and work closely with the General Manager on turning business goals into technical execution.

A major part of the role is helping us move toward a much more AI-native development process — where agents become deeply integrated into how software is specified, built, tested, reviewed, and maintained.

This is not a pure management role. We want someone who leads by building.

WHAT YOU'LL DO

• Own the architecture, technical direction, and major engineering decisions.
• Lead and mentor the development team.
• Stay hands-on with backend development and difficult technical problems.
• Drive the adoption of AI agents across the development process.
• Improve testing, CI/CD, observability, reliability, and developer productivity.
• Keep a mature production system evolving without unnecessary rewrites or complexity.
• Translate business goals into practical technical plans.

WHAT WE'RE LOOKING FOR

• Strong senior-level backend engineering experience, ideally in TypeScript / Node.
• Experience acting as a Tech Lead, Staff Engineer, Principal Engineer, Lead Engineer, or similar.
• Deep technical judgment and the confidence to be the company's main engineering authority.
• Strong hands-on experience with modern AI coding tools and agentic development workflows.
• Experience owning and evolving mature production systems.
• Comfortable leading a small engineering team while remaining close to the code.
• Strong communication and a pragmatic approach to engineering.

Our stack is NestJS, Vue 3 / Vite, PostgreSQL, and GCP. Exact stack experience is useful, but strong adjacent experience is perfectly fine.

NICE TO HAVE

• Shopify or e-commerce experience.
• NestJS, Vue, or GCP experience.
• Founder, founding-engineer, or early-stage startup experience.
• Experience introducing AI-first development practices across a team.

WHY AMPLIFY

• Real ownership. You'll have genuine authority over the technical direction of the company.
• Established and profitable. A mature product, thousands of customers, and a real business behind it.
• Build the next development model. You'll have the freedom to push beyond simply using AI coding tools and help design how an AI-native engineering team actually works.
• High autonomy. The team works independently against clear company objectives rather than through layers of management.
• Meaningful performance bonuses. When the company does well, the team shares in the upside.
• Small team, visible impact. Your decisions quickly translate into real changes in the product and the business.

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

Job Description

• Proven ability to elicit and document business rules embedded in legacy applications.
• Experience analysing incident/ticket history to establish operational baselines and pain points.
• Skilled at facilitating functional discovery workshops with mixed business and technical stakeholders.
• Able to define and baseline SLAs, KPIs, and success metrics for a support engagement.
• Comfortable using AI tooling to accelerate analysis while verifying outputs against source data.
• Work on legacy or mission-critical systems.

Job Responsibilities

• Lead functional discovery workshops to map what the mainframe applications do from a business perspective.
• Document critical business rules, batch dependencies, and functional pain points tied to legacy code.
• Analyse incident and backlog history, using AI-assisted clustering where useful, to establish a current-state support baseline.
• Define SLA, KPI, and success-metric baselines for the proposed maintenance model.
• Triage and prioritize candidate use cases for the maintenance pilot by business impact.

• Consolidate current-state findings into the assessment deliverables alongside the architect.

   

Department/Project Description

The engagement supports a maintenance assessment and advisory for a legacy mainframe environment built primarily on COBOL, running mission-critical batch and online workloads. The objective is to establish a fact-based understanding of the current application estate and its support model, and to define a scoped, low risk maintenance pilot as the basis for a potential longer term managed services engagement.

The initial advisory phase is an assessment structured in three stages: a scope-alignment workshop to agree services, ownership, and boundaries; a current-state assessment of the code estate, data, batch/online flows, operations, and ticket history to establish baselines and pain points; and a pilot-identification stage to prioritize candidate use cases and define objectives and success metrics. The phase is diagnostic in nature — it covers evaluation, characterization, and effort estimation only, with no code remediation or production changes performed during assessment. Success depends heavily on timely access to client subject-matter experts and to the target environment.

About the Role:

We are looking for a Senior Software Engineer to design, build, and own significant components of the core query engine of a large-scale distributed data platform. You will lead work across query planning, optimization, and execution — driving architectural decisions, mentoring middle engineers, and pushing the platform's performance and scalability boundaries across all major clouds.

This is a systems-level, backend engineering role focused on distributed data processing internals — not application development or CRUD services.

Responsibilities:

• Architect, design, and implement significant components of the query engine — planner, optimizer, execution operators, memory management, and data access layers.
• Write and review high-quality, performance-critical code in Java and/or C++.
• Own end-to-end delivery of features from technical design through production rollout.

• Programming: Strong proficiency in Java or C++, with deep understanding of OOP, systems design, memory management, and concurrency. Candidates strong in both are especially valued.
• SQL & Data: Advanced SQL skills and strong understanding of query execution internals — planning, optimization, and operator implementation.
• Data processing systems experience: Demonstrated experience building or extending data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 5+ years in backend/systems software engineering, with a track record of owning significant components.
• CI/CD & DevOps: Solid experience with Jenkins and modern engineering workflows.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes.
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and rigorous code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, leading technical designs, or owning components end-to-end.

Desired Skills:

• Deep experience with Apache Arrow (columnar in-memory format).
• Hands-on experience with Apache Calcite (SQL parsing, planning, optimization framework).
• Experience with Gandiva or LLVM-based expression compilation and code generation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Deep familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Deep understanding of query planning, optimization (cost-based, rule-based), and execution internals.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Track record of performance optimization at the systems level — profiling, vectorization, cache/memory-conscious design.
• Prior experience contributing to open-source data infrastructure projects.
