About Sine Engineering

Sine Engineering builds the technology behind reliable drone autonomy, delivering communication, navigation, and control systems that enable coordinated multi-drone operations. More than 200 UAV manufacturers rely on our solutions, and our technology powers many of the interceptor operations active today.

Through our dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological advantage.

Any drone, any scale, anywhere - resilient communication, navigation, and coordination built for the age of autonomy. Our products have already proven their effectiveness in real combat conditions in Ukraine.
 

About the Role

We are looking for a Delivery Manager to own the technical direction and delivery of projects across a portfolio of strategic customer accounts.

This role bridges client needs and engineering execution. You will engage early, often before a solution or delivery scope is fully defined, to understand the client’s platforms, operational use cases, technical constraints, and future plans. You will then translate that understanding into a realistic technical roadmap and coordinate its implementation with Client Integrations, Product, Demo, Military Support, and other engineering teams.

You will work closely with a Key Account Manager. While the Key Account Manager owns the overall account strategy, customer relationship, and commercial outcomes, you will be responsible for the technical account plan, solution feasibility, and successful technical delivery.

This is neither a traditional sales role nor a purely administrative project management position. It requires sufficient engineering depth to make and defend technical decisions, combined with the ability to lead complex, customer-facing initiatives across multiple teams.
 

Responsibilities

Technical Account Ownership

• Maintain a comprehensive and up-to-date technical view of each assigned account, including client platforms, system architecture, completed and planned integrations, operational use cases, risks, and dependencies.
• Develop and maintain a technical account roadmap aligned with the Account Development Plan and the client’s product and platform development strategy.
• Participate in customer discussions before scope commitments are made, ensuring technical feasibility, constraints, effort estimates, and dependencies are clearly understood.
• Translate customer and operational requirements into a well-defined technical scope, integration approach, delivery plan, and acceptance criteria.
• Own solution feasibility and technical commitments for assigned accounts.
• Identify technically viable opportunities to expand Sine solutions across additional customer platforms, products, and use cases.
• Build trusted relationships with customers’ engineering and technical teams.
  
  Technical Delivery
• Own the technical outcomes of discovery activities, integrations, proof-of-concepts (PoCs), demonstrations, and acceptance testing.
• Define project concepts in collaboration with engineers and technical specialists.
• Establish technical milestones, dependencies, risks, test objectives, and acceptance criteria.
• Assemble and align the appropriate technical team for each opportunity based on scope and complexity.
• Coordinate engineers and technical contributors who do not necessarily report directly to you.
• Monitor delivery progress and proactively escalate technical risks, resource constraints, and scope changes.
• Ensure technical decisions, configurations, test results, and known limitations are properly documented.
• Facilitate smooth handover from internal teams to customer deployment, support, or ongoing development.
   

Required Qualifications

• Experience delivering complex hardware, embedded systems, or system integration projects for external customers.
• Ability to understand system architecture and make sound technical decisions.
• Experience translating customer or operational requirements into technical scopes and implementation plans.
• Experience coordinating multidisciplinary engineering teams and specialists without direct reporting authority.
• Ability to estimate technical effort, identify dependencies, and assess delivery risks.
• Strong customer-facing communication skills, including the ability to explain technical limitations and navigate challenging delivery discussions.
• Structured approach to planning, documentation, risk management, and reporting.
• Professional working proficiency in both English and Ukrainian.
• Willingness to travel to customer sites as required.
   

Nice to Have

• Engineering background or strong technical expertise in UAVs, robotics, embedded systems, RF communications, navigation systems, electronics, or a related field.
• Experience in defense technology, UAVs, UGVs, autonomy, communications, RF systems, ISR, electronic warfare (EW), or GNSS-denied navigation.
• Experience as a Technical Account Manager, Solutions Architect, Integration Lead, Technical Project Manager, or Engineering Delivery Lead.
• Understanding of UAV subsystems, including telemetry and control links, video transmission, flight controllers, navigation systems, antennas, onboard electronics, and ground control stations.
• Experience with field testing, flight testing, demonstrations, or formal customer acceptance processes.
• Experience collaborating with Product and R&D teams to address customer-driven product requirements.
• Experience working with military users, defense organizations, or operational support teams.
• Experience coordinating external engineering partners, vendors, or subcontractors.
   

Why Join Us?

• If you’re excited about building technology that shapes the future of drone autonomy and want your work to have a meaningful impact on defense and security, we’d love to hear from you.
• If this role aligns with your experience and ambitions, don’t hesitate to apply. We’re looking for people who share our drive to push the boundaries of what’s possible and deliver technologies that make a real-world difference.

Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• immediate access to AIBY’s historical data from 70+ apps to see what works
• centralized Legal, Finance, and HR so you can focus 100% on the product and the users
• significant UA budgets and infrastructure already in place

What you will do:

• P&L Ownership: you’re 100% accountable for the revenue, marketing spend, and operational costs of your unit
• Strategic Roadmap: define the “Why” and the “When”. You decide which features to build based on their projected impact on retention and monetization

• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player

About the Role

We're looking for a senior Data Architect to design and modernize an Azure data platform, including the data architecture underpinning GenAI/RAG/Agentic applications. This is an architecture role, not hands-on RAG/ML development — the focus is on how enterprise data and knowledge are ingested, prepared, stored, governed, and made available for retrieval and AI consumption.

Must-Haves

• Azure Cosmos DB — hands-on experience with data modeling, partitioning, indexing, RU/throughput and cost optimization, consistency, Change Feed
• Proven experience designing data platforms supporting GenAI/RAG use cases
• AI-ready data architecture experience
• A real project where the candidate designed or contributed to the data architecture supporting a RAG, GenAI, or Agentic AI application
• Azure Synapse Analytics — depth across workload patterns (Pipelines, Spark, Serverless SQL, Dedicated SQL Pools)
• Azure Databricks
• Azure SQL MI / SQL Server / T-SQL
• Azure Data Lake / Lakehouse architecture
• Azure Functions
• Experience with structured and genuinely unstructured data (documents, PDFs, scans, images, email, free text)
• Metadata/configuration-driven ingestion — reusable, scalable design for onboarding new data sources
• Demonstrated architecture ownership — real decisions made, not just pipeline implementation
• At least 4 years of recent (not dated) hands-on Azure experience
• Must be an Architect by role, not a Data Engineer

What You'll Do

• Take over an existing, problematic data platform, quickly assess it, and deliver both tactical fixes and a longer-term target architecture
• Design a reusable ingestion architecture for heterogeneous sources (databases, APIs, files)
• Make technology-neutral calls on when Databricks/Synapse/ADF are actually needed — and when they're not
• Produce detailed, implementation-ready architecture documentation for engineering teams
• Own data governance, data quality, and incremental processing
• Communicate effectively with both technical and business stakeholders

A Note on GenAI/RAG

You won't be building RAG solutions or AI agents yourself. What's required is experience designing the data architecture around such applications — how enterprise data and knowledge get ingested, processed, indexed, and made available for retrieval and AI consumption (document processing, OCR, chunking, embeddings, vector search, etc.), including where Cosmos DB fits into that picture.

Interview Process

1. Intro call
2. Technical interview (~1 hour)

Be ready to walk through 2–3 concrete project examples using: problem → options considered → your decision → rationale → implementation → result. The focus is less on definitions and more on how you think as an architect and how quickly you can turn a messy existing situation into practical direction for an engineering team.

The role is based in the Kyiv region, and we will expect you to work full-time in the office. We have a shuttle service from the nearest metro station.
