GlobalLogic is working on an advisory engagement to design an AI-powered search assistant for project documentation accumulated over roughly 20 years, currently stored on an isolated, internet-disconnected file server. The dataset spans 2-3 TB including test artifacts, with core documents in the 1-10 GB range and about half the volume in the legacy .xls format. The goal is to let developers and SMEs query specification documents in natural language and get answers assembled across multiple related customization projects, instead of manually tracing code history and cross-referencing documents by hand. The target architecture connects the document store (likely SharePoint) to a generative AI search layer, with NotebookLM as the initial reference point and enterprise alternatives such as Vertex AI Agent Builder under evaluation.

Job Description

• 3+ years of commercial experience with Python, including work on data processing and ETL pipelines
• Experience parsing and transforming document formats (Excel including legacy .xls, PowerPoint, Word, PDF) using libraries such as pandas, openpyxl, xlrd, python-docx, python-pptx
• Experience with OCR technologies for extracting text from images and embedded objects (e.g. Tesseract, Google Vision API, Azure Computer Vision) 
• Understanding of RAG (Retrieval-Augmented Generation) architectures, embeddings, and vector search
• Experience integrating with cloud storage and collaboration platforms via API (SharePoint / Microsoft Graph API or similar)
• Written and spoken English proficiency equivalent of B2 or higher
• Ability to work with incomplete requirements during an advisory and PoC phase
• Self-reliant, comfortable proposing and testing technical solutions with limited direction

Nice to have:

• Familiarity with NotebookLM, LangChain, LlamaIndex, or Vertex AI Agent Builder
• Experience designing incremental indexing or delta-update mechanisms for search systems
• Experience working with enterprise clients in isolated or air-gapped network environments
   

Job Responsibilities

• Design and implement a format-conversion pipeline for legacy files (.xls, .ppt) into AI-readable formats (.xlsx, PDF, or Markdown)
• Build extraction logic for unstructured data inside Excel files, including text in shapes via drawing-layer analysis and OCR processing of embedded images
• Develop and validate an incremental update mechanism so only new or changed files are reprocessed
• Implement data cleansing logic to exclude obsolete or duplicate files (marked "old", "BKUP") from search results
• Evaluate NotebookLM against alternative platforms (e.g. Vertex AI Agent Builder) and document findings to support the Advisory Phase comparison
• Build PoC search functionality supporting natural language queries across multiple customization specification documents

About us

UAPP.AI is a product company. We build AI-powered mobile applications used by over 10 million people. The full product cycle stays in-house — from the idea to scale and monetization. Decisions are fast and data-driven, without bureaucracy.
 

The Role

We run a subscription product across mobile and web. Payments go direct, through our own provider stack — Stripe, Unlimit, Payable, Traspay, SolidGate, Checkout.com, ADN, Apple.

We are looking for a Head of Payments to strengthen the payments direction: onboarding new providers and products, domain compliance, fees, reconciliation and approval rate on rebills.

The role is hands-on: you work alongside the team, not only assign tasks.
 

What you will do

• Provider onboarding: new PSPs, plus new products with providers we already work with — applications via agents, merchant ID registration, entities
• Domain compliance: preparing the websites we submit for onboarding to meet provider requirements — knowing what has to be stated, how and where (terms, refund and subscription cancellation policy, pricing, product description, contacts, support) and keeping it current after underwriting
• Recurring and rebills: retry logic, soft/hard declines, payment-method update flows, reducing involuntary churn
• Approval rate: audit by GEO, provider and card scheme, routing and cascading priorities
• Commercial terms: negotiating fees and rolling reserves, auditing commissions to see where the money leaks
• Reconciliation and reporting: settlement reconciliation, payment reporting, cost transparency per product and provider
• Analytics: your own dashboards on payment metrics, built with AI tools
   

What we expect

• 4+ years in payments, at least 2 at Head / Lead level
• A portfolio of several PSPs: Stripe, SolidGate, Checkout.com, Unlimit and similar
• Merchant onboarding: applications, merchant IDs, underwriting
• Understanding of provider compliance requirements for websites: what has to be stated and where
• Recurring payments: rebills, decline handling, churn caused by failed payments
• Approval-rate and fee optimization — with numbers behind it
• Willingness to work hands-on and use AI tools daily
• English B2+
   

Nice to have

• Mobile subscriptions, IAP, web-to-app funnels
• Negotiating enterprise terms with Tier-1 providers
   

What we offer

• Fully remote, full-time
• A working stack and a team already running the direction — you join a live process
• Fast decisions without long approval chains
• A product with 10M+ users and a growing subscription business — the result of your work shows on the revenue chart
• Competitive USD-pegged compensation, reviewed on results

About Lexidesk
 

Lexidesk is an AI intake platform for US law firms. Our AI agent answers calls and messages from potential clients 24/7, qualifies them, and books them into the firm's calendar, so lawyers stop losing clients to voicemail. 

We're a small, fast-moving team building on the latest AI tooling, and our customers are real law firms that rely on us to talk to their clients.
 

You'll be our first dedicated support hire, working directly with the founder.
 

What you'll do
 

Keep customers running
 

• Own the Intercom inbox: resolve tickets and follow through until the customer is actually unblocked.
• Take phone support calls from US and UK law firms.
• Handle technical implementation: connect firms' phone systems, calendars, and CRMs to Lexidesk via integrations, webhooks and API settings.
   

Make support smarter
 

• Build and maintain our Help Center.
• Train and improve the Intercom AI support bot so it answers most questions before a human is needed.
• Design Intercom automations and propose how support can be faster, more self-serve and better for customers.
   

Grow accounts
 

• Proactively check on customers who haven't reached out. Catch problems before they become churn.
• Spot where a firm would benefit from a feature they aren't using yet, and suggest it.
• Ask happy customers for reviews and testimonials.
   

What we're looking for
 

• English at B2+ or better. You'll be writing to and speaking with native speakers daily.
• You already know what an API request and a webhook are, and you are interested in AI.
• You can explain technical things to a non-technical lawyer without jargon, and without losing patience on the third try.
• You like customers. You want a long-term role in support/customer success.
• Available Mon–Fri 13:00–21:00 Kyiv time, and not currently studying.
• Bonus: experience with Intercom, help centers, telephony/VoIP, or a US-facing SaaS.
• Bonus 2: experience with legal/legatech industry.
  
   

What we offer
 

• $1000–$1,500/month base depending on experience.
• Performance bonuses tied to customer reviews and account growth. Top performers meaningfully out-earn the base.
• Paid AI tools (Claude and others). You'll use them daily.
• Direct line to the founder; your ideas ship, not sit in a backlog.
• Growth path: as we scale, this role grows into leading support / customer success.

• Version Control: Confident with Git / GitHub workflows.
• 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.

DESIRED SKILLS

• Experience with Apache Arrow (columnar in-memory format).
• Familiarity with Apache Calcite (SQL parsing, planning, optimization framework).
• Exposure to Gandiva or LLVM-based expression compilation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines(e.g., Presto, Trino, or similar).
• Understanding of query planning, optimization, 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.
