We build miniature radar seekers. You have to extract small, low-RCS drone tracks from heavy background clutter, EW interference, and motor noise. You have to run this math on severely constrained silicon. You are bound by strict compute, memory, and thermal limits. The processing loop must close in milliseconds. There is no cloud, no heavy GPU, and no room for inefficient code.

Main Responsibilities

You own the math and the metal. You design the radar algorithms (FMCW, CFAR, beamforming, MIMO virtual arrays) and the advanced tracking math (Kalman filters, multi-target tracking, clutter rejection). You implement this across the SoC architecture – managing the heavy lifting on FPGA and DSP accelerators and writing the bare-metal C or RTOS code for the microcontrollers. You manage the memory architecture, the DMA transfers straight from the ADCs, and the low-level peripheral drivers. You also own the data handoff, packaging clean point-clouds and track histories for our Edge ML classification models.

PROOF OF EXECUTION

Degrees do not matter here. We want to see the algorithms you have built AND physically deployed on embedded hardware. If you only simulate perfect radar returns in MATLAB and have never managed a memory buffer or a DMA transfer, do not apply. Show us how you squeezed complex tracking math into a constrained chip (FPGA, RFSoC, or MCU) without blowing up the latency. We expect you to take raw field data on a Tuesday, rewrite the algorithm, and flash a new firmware image to the seeker on a Thursday.

Mandatory Requirements

You must work in our Kyiv lab every day. We go from the bench to field testing in days, not months. The financial package includes a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We cover all logistics and remove all friction so you can focus 100% on building hardware.

We offer

This role requires your daily physical presence in our Kyiv lab. We move from the test bench to live field validation in days, not months. We provide a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We remove all financial and logistical friction so you can focus entirely on shipping hardware.

About DRCT
 

DRCT is evolving from an NDC aggregator into a B2B operating platform for travel sellers.

Our goal is to give travel sellers one infrastructure layer to manage travel distribution, starting with Air and expanding into Hotels, Payments and other travel products.

We already have strong Air distribution capabilities and an established customer base. The next phase is about building a repeatable growth engine: acquiring the right customers, activating them quickly, expanding them across products and increasing their lifetime value.
 

About the role
 

We are looking for a Head of Growth who will own this transformation end-to-end.
You will be responsible for building the system that takes DRCT from:

customer acquisition → activation → transaction → multi-product adoption → retention → expansion → referral.

You will work directly with the founders, CEO, Product and Commercial teams and will have significant autonomy to build the Growth function.
 

What you’ll do
 

• Define and own DRCT’s growth strategy — identify our ICP, strongest customer segments, positioning and key growth opportunities.
• Build and scale customer acquisition across outbound, partnerships, referrals, account-based and product-led channels.
• Improve customer activation — optimise the journey from registration to first transaction and drive faster time-to-value.
• Drive customer expansion and retention — develop strategies to grow customers from Air → Hotels → Payments, increase transaction frequency and build long-term customer value.
• Own growth analytics — track key metrics such as CAC, LTV, activation, retention and contribution, and use data to identify what works and what to scale.
   

What success looks like
 

We are not measuring success by traffic, followers or the number of registered accounts. You’ll be focused on:

• Growth in active transactional customers
• Increased multi-product adoption
• Growth in customer contribution
• Improved 30 / 90 / 180 / 365-day retention
• Efficient CAC and payback by acquisition channel
   

What we’re looking for
 

• 7+ years in B2B SaaS, fintech, marketplaces, travel tech or another transactional platform business;
• experience owning growth rather than only marketing;
• strong understanding of funnel analytics and unit economics;
• experience building acquisition channels from scratch;
• experience with product-led growth and/or account expansion;
• strong commercial judgment;
• ability to work hands-on with data, product and sales;

• Working hours shift into the evening - roughly until 9-10 PM Kyiv time

• Calls with the team two to three times per week at the start, one to two later on

• Everything else is async, you plan your own day

• Evening availability on agreed days is mandatory and not open for renegotiation after you start

If evening hours don’t work for you, it’s better not to spend time applying.

Requirements
 

Building processes from scratch

• Experience joining a project with no QA in place and building everything yourself

• Ability to set up a manual process from zero: critical flow map, test plan, regression suite, release checklist, bug workflow

• Experience with CI/CD and how tests live inside a pipeline

AI testing

• Hands-on experience testing products with an LLM or ML underneath

• Understanding of how to verify non-deterministic output, where there is no single correct answer to assert against

• Experience with evaluation sets, scoring response quality, and catching regressions after a model or prompt change

• Familiarity with common failure modes: hallucinations, unstable responses, false refusals
 

API and backend

• Confident API testing with Postman or equivalent

• Ability to read logs and localise an issue to the device, the app, or the backend

• Working understanding of cloud services

Communication

• English at Advanced (C1) level or above — fluent spoken and written, no pauses to find words

• Comfortable holding technical discussions directly with a CTO

• Self-driven: nobody will hand you tasks every morning
 

Strong pluses

• Experience testing products where an app works together with a physical device

• Understanding of BLE: pairing, reconnection, behaviour on connection loss, data sync

• Experience with OTA firmware updates delivered through an app

• Working with audio as test data

• Experience at early-stage startups where processes don’t exist yet and have to be created

• Crash and feedback triage during beta, with Sentry or Crashlytics

• Understanding of privacy requirements: verifying data deletion and recording indicators

What you’ll be doing

• Regression testing ahead of weekly releases

• Feature testing before go-live

• Exploratory testing across device → cloud → app

• Building the QA process from scratch and growing it over time

• Auditing existing automated tests and gradually extending them

• Bug and crash triage during beta

What we offer

• Long-term engagement with the prospect of scaling up to full-time

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.

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

• 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
