About the Role

We're building AI-powered products and we need someone who can work across the full stack without needing a handoff at every layer. This role spans backend services, AI orchestration, real-time voice systems and frontend interfaces. You'll own features from design to deployment and be expected to debug issues that cut across all of them.

If your experience is limited to a single layer of the stack, or your AI exposure hasn't gone beyond side projects, this role isn't the right fit.

• Design and build backend services and APIs using Node.js and Python
• Build and operate AI workflows using LangChain and LangGraph for orchestration, chaining and agent logic
• Use LangSmith for tracing, evaluation and debugging of AI pipelines in production
• Integrate real-time voice capabilities using LiveKit and related voice AI infrastructure
• Build frontend interfaces using React and Next.js that are fast, reliable and handle streaming AI responses cleanly
• Own features end to end from initial design through deployment, monitoring and iteration
• Handle async workflows, background jobs and real-world failure scenarios
• Set up logging, tracing and alerting so production issues surface before users report them
• Debug problems that span frontend, backend, AI pipelines and infrastructure simultaneously
• Work with product to turn vague requirements into well-scoped, shipped features
• Review code and maintain technical standards across the team

What You'll Need

• 5+ years of professional software engineering experience in production environments

• Demonstrated experience building AI workflows using LangChain, LangGraph or comparable frameworks
• Working knowledge of LangSmith or equivalent tooling for AI observability and evaluation
• Experience building and operating backend APIs used by real users
• Solid experience with React and Next.js or equivalent frontend frameworks
• Strong understanding of async programming, streaming (SSE/WebSocket) and frontend state management
• Experience with MongoDB or similar document stores including data modelling trade-offs
• Comfort deploying and operating services on AWS, GCP or equivalent cloud environments
• Ability to debug across frontend, backend and AI layers using logs, traces and metrics

Good to Have

• Hands-on experience with LiveKit or other real-time voice and audio pipeline systems
• Prior work on conversational AI, voice agents or multi-modal AI products
• Experience with RAG pipelines, LLM evaluation or fine-tuning workflows
• Background in a fast-moving startup or high-velocity product environment

What We Expect

• You take ownership of what you build and don't wait for someone else to fix broken things
• You understand trade-offs and can communicate them clearly to non-engineers
• You think in systems, account for failure modes early and design for graceful degradation
• You leave code and documentation in better shape than you found it

What You'll Get

• End-to-end ownership of features that ship to real users
• Direct influence over technical and architectural decisions
• Work on systems that are used daily by real users
• A small team where your contributions have visible product impact

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.

The role. A top-of-funnel paid acquisition role that owns user acquisition across the whole portfolio end-to-end — running it, not supervising it. You start by personally running growth for at least three apps, then scale to five to seven as you build repeatable systems and, over time, a team beneath you. Paid and organic are treated as one connected acquisition system. This is a builder-operator role: you set up the growth function from scratch — campaign infrastructure, measurement, reporting, and playbooks.

Who we look for

• Has personally deployed meaningful paid spend at a consumer subscription company (~$10M+/year, or smaller budgets run with real rigor) with direct ownership of the numbers.
• Hands-on with the modern stack: an MMP (AppsFlyer, Adjust, or Singular), Superwall, Amplitude/Mixpanel, Customer.io 
• SKAN-fluent; builds and pressure-tests LTV and payback models 
• Has operated across 3–7 apps or product lines at once 
• Player-coach who executes today with a clear path to hire and lead a small team; ideally arrives with 2–3 trusted specialists (e.g. a UGC/creative producer and an analyst).

What you'd own

• Plan, launch, and optimize paid UA hands-on across Apple Search Ads, Google (UAC + search), Meta, TikTok, and paid web — budgets, bids, audiences, and creative testing against payback and CAC per app.
• Drive organic in parallel: ASO, store-listing conversion, web-to-app.
• Build the measurement backbone — stand up the MMP, configure SKAN and postbacks, run incrementality tests, reconcile web-vs-app attribution.
• Own the experiment roadmap independently: bring your own channel and creative ideas, size them by expected payback, run them without waiting for a task list.
• Manage secondary paywall/funnel work and coordinate lifecycle (email/push) with the analytics and lifecycle hires.

Comp. up to $150K (+performance bonuses) tied to portfolio payback and growth, with equity options after the first year

Project Overview:

We are seeking a Senior Backend Engineer with strong expertise in Node.js, TypeScript, and AWS Lambda to build a decoupled serverless application. The role focuses on implementing plan management endpoints with Fastify and ts-rest, designing a SQL Server schema with Prisma migrations, and building a deterministic calculation engine covering forecasts, SMV, derived metrics, and goal deltas — while integrating internal APIs with caching, retries, and circuit-breaker patterns, wiring the full AWS infrastructure via Serverless Framework, and ensuring quality through thorough unit and integration tests.

Customer Overview:

USA influencer marketing platform for organizations looking to advance their creator marketing. Its enterprise-grade technology and industry-leading intelligence facilitate scaled creator discovery, streamlined workflows, and robust reporting, while ensuring compliance and brand safety.

Responsibilities:

• Implement plan and plan-item endpoints with Fastify + ts-rest, validated by Zod schemas shared with the frontend.
• Build the deterministic calculation engine (forecast → adjustment → SMV → derived metrics → totals → goal deltas), including BRD edge cases (Twitch avg_concurrent_views, payout exclusivity, missing-data defaults).
• Design the SQL Server schema and Prisma migrations; ensure reviewable raw-SQL output for the DBA team.
• Build adapters for Lists/Collections and Campaign Service with caching, fallbacks, circuit-breaker, and structured error handling.
• Integrate AWS infrastructure (API Gateway, Lambda, RDS, ElastiCache, Secrets Manager, S3) via Serverless Framework; wire Coralogix logs/metrics/traces.
• Write thorough unit and integration tests, especially around the calc engine; pass Trivy + SonarQube gates in CI.
   

Skills/Requirements:

• 4+ years with Node.js and TypeScript in production backend services.
• Hands-on AWS Lambda + API Gateway, comfortable with serverless tradeoffs (cold starts, 30s/10MB limits, concurrency).
• Experience with Prisma (or comparable ORM) and a relational database; SQL Server experience a plus.
• Strong API design background — REST + JSON Schema/Zod/OpenAPI — and integration patterns (caching, retries, circuit breakers).
• Comfortable with Serverless Framework / IaC and GitLab-style CI/CD.

Nice to have:

• Fastify and ts-rest experience specifically.
• Background in calculation/forecasting engines or financial/analytics computations.
• Familiarity with Coralogix or comparable APM/log platforms.
