About the role 

We're looking for a Senior Data Architect to join a long-term engagement with an enterprise client. You'll take ownership of an existing, complex Azure data platform and quickly assess, stabilise and modernise it. You'll also design the data layer behind GenAI, RAG and Agentic AI applications. 

This is not a hands-on LLM or AI-agent development role. What matters is that you have designed, in production, how enterprise data and knowledge is ingested, prepared, stored, governed and made available for retrieval and AI consumption. 

What you'll do 

• Own the architecture of an existing Azure data platform: assess it fast, separate tactical fixes from long-term target architecture, and move both forward in parallel. 
• Deliver implementation-ready architecture: detailed documentation, diagrams and recommendations that engineering teams can act on. You'll be expected to show meaningful output within the first 1–2 weeks. 
• Design the data and knowledge layer for RAG and Agentic AI applications: document processing, OCR and text extraction, metadata, chunking, embeddings, and vector search and retrieval. 
• Design scalable, metadata- and configuration-driven ingestion for many databases, APIs and file-based sources. 
• Work with structured and genuinely unstructured data (PDFs, scans, images, emails, free text). 
• Make technology-neutral decisions about when Synapse, Databricks, ADF, Azure SQL or a Lakehouse are justified, and when they only add complexity. 
• Improve performance, scalability, maintainability and data quality, including batch, incremental processing and incremental refresh. 

Must-have 

• Strong, recent experience as an enterprise Azure Data Architect, with clear architecture ownership. 
• At least one real production project (not a POC) where you designed or owned the data architecture behind a RAG, GenAI or Agentic AI application. 
• Azure Cosmos DB, in depth (essential): data modelling, partition-key strategy, indexing, RU/throughput and cost optimisation, scaling, consistency, Change Feed, and knowing when Cosmos DB is the right choice and when it isn't. 
• Azure Synapse Analytics, current and in depth: Pipelines, Spark, Serverless SQL, Dedicated SQL Pools, and how Synapse compares with Azure SQL, ADF, ADLS, Databricks and Fabric. 
• Azure Databricks, Azure SQL MI / SQL Server / T-SQL, Azure Data Lake / Lakehouse architecture, and Azure Functions. 
• Strong data modelling: fact and dimension tables, star schemas, and optimising analytical models. 
• Proven experience taking over a problematic legacy data platform and modernising it. 
• Ability to work independently with incomplete information and turn analysis into concrete deliverables quickly. 
• Fluent English (C1 preferred) and strong communication with both technical teams and business stakeholders. 

What we offer 

• A 12-month full-time contract with a long-term perspective 
• A high-impact architecture role at the intersection of enterprise data platforms and GenAI 
• Fully remote work 
• A short hiring process: an intro call and a 1-hour technical interview 

How to apply 

Please send a CV tailored to this role. The client screens CVs strictly and won't review a generic CV or a list of keywords. For each relevant project, please include: 

• start and end dates, context, and your personal role and decisions 
• the Azure services you used (Cosmos DB, Synapse, Databricks and so on) and how you used them 
• for your RAG/GenAI project: what the application did, what you personally owned, how the data was prepared for retrieval, which storage and vector-search technologies you used, whether Cosmos DB was part of it, and whether it was in production 

Please also include: 

• your expected hourly rate (USD) 
• your English level 
• years of experience 
• your country of residence and your citizenship 
• your availability date 

Shortlisted candidates will be asked to complete a skills matrix.

estaie is the AI-native extended-stay platform for 15 to 365-night stays. We connect hotels, holiday homes, channel managers, PMSs, payment providers and other travel systems through intelligent inventory, pricing, search and distribution infrastructure. We operate globally, with hubs in Dubai and Riyadh. Our AI layer powers dynamic pricing, agentic lead generation, smart inventory orchestration and autonomous operations for operators, corporate bookers and digital nomads alike.

Location: Remote-first (MENA time zone alignment required: at least 8 hours per day overlapping with Gulf Standard Time, UTC+4)
Reports to: Nimit Solanki, CTO & Co-founder
Leads: Forward Deployed Engineers (Integrations)
Type: Full-time
Shape of the role: roughly 50% people and delivery leadership, 50% hands-on engineering

THE ROLE

You will build and lead our Forward Deployed Engineering team: the engineers who connect estaie to the hospitality ecosystem and make those integrations work in production. You own how the team works, what it ships, and the quality bar it holds.

You are also one of the team's strongest engineers. You take real integration and AI work yourself, review PRs, debug production issues alongside your team, and lead by example rather than from a dashboard. You partner directly with the CTO on architecture and technical strategy, and with product, sales and partnerships on what gets built and when.

WHAT YOU'LL DO

Lead the FDE team

• Hire, onboard and grow a remote team of Forward Deployed Engineers, and set clear expectations on ownership, quality and pace.
• Run delivery across many partner integrations at once: prioritise, unblock, and keep commitments to partners realistic.
• Coach engineers on integration design, debugging across systems, clean code and working directly with partners.
• Run 1:1s, give direct feedback, and build a culture of accountability, async collaboration and written decisions.

Stay hands-on

• Write production code in TypeScript, Python and SQL, and own some integrations end to end yourself.
• Review PRs and set the engineering standard for testing, observability and documentation.
• Join the hardest partner debugging sessions and production incidents, and lead the post-mortems.

Own the integration platform

• Design the patterns every integration follows: authentication (including OAuth 2.0 token refresh), signed webhooks, retries with backoff, rate limiting, idempotency and error handling.
• Own the canonical data model that normalises inventory, rates and availability from partners with different schemas.
• Make sure we never oversell: concurrency control on inventory, handling of out-of-order and late events, and reconciliation jobs that catch drift with external systems.
• Build the shared tooling that makes each new integration faster than the last: mock partner servers, contract tests, onboarding tools, dead-letter queues with replay.

Bring AI into production safely

• Lead the use of LLMs and agents across integration workflows, such as mapping messy partner data, operational copilots and automation.
• Set the guardrails: structured output with schema validation, human review for low-confidence results, eval sets as CI gates, and least-privilege tool access for agents.
• Keep AI cost and latency under control with queues, rate limiters, caching and model routing.

Reliability and partners

• Own uptime, security and performance of the integration layer across regions and environments.
• Act as the senior technical contact for key partners, channel managers, PMSs and payment providers.
• Feed what you learn in the field back into product and platform priorities.

TECH STACK

• Frontend: Next.js, React, TypeScript, TailwindCSS; Laravel and Vue.js on parts of the core platform
• Backend: Node.js / NestJS, Python (FastAPI) for AI and data services, REST APIs and webhooks
• Data: PostgreSQL (with pgvector), MySQL, Redis, BigQuery, Datastream
• Async and events: BullMQ, Pub/Sub, Kafka / Redpanda
• AI: Vertex AI (Gemini, Claude), LangChain, embeddings and vector search, agentic workflows
• Infrastructure: GCP (Cloud Run, Cloud Build, IAM, Secret Manager), Docker, Terraform, GitHub Actions
• Security and edge: Cloudflare (WAF, Zero Trust), OAuth 2.0, JWT
• Observability: Cloud Logging, Prometheus, Grafana, alerting and anomaly detection
• Integrations: Channel managers, PMSs, OTAs and supplier APIs; payment gateways such as Stripe, Tamara and Checkout.com; WhatsApp Business API and Twilio

WHAT YOU BRING

• 8 to 12 years of software engineering experience, including 3+ years leading engineers in a high-growth startup, SaaS or platform company.
• You still code. Strong, current hands-on skills in TypeScript (Node.js / NestJS, React / Next.js), SQL and PostgreSQL, plus working Python.
• A track record of building and running third-party integrations in production: webhooks with signature checks, idempotency, retries, rate limits, and data sync or reconciliation.
• Solid grounding in distributed systems: transactions and concurrency, queues and event-driven design, out-of-order events, and fault tolerance.
• Production experience with LLMs, including how to evaluate them, constrain them and keep their costs in check.
• Cloud deployment experience with Docker and CI/CD, ideally on GCP.
• Experience leading a remote, distributed team with an async, written culture.
• Professional-level English: you can run a technical call with an external engineering team and turn it into a plan, and write clear documentation, PR reviews and post-mortems.
• Bias for action. You debug, document, automate and measure, and you care about products that work, not just systems that run.

NICE TO HAVE

• Hospitality, hotels, holiday homes, travel-tech, fintech, marketplace or other integration-heavy background is an absolute plus and will be weighted heavily.
• Hands-on experience with channel managers, PMSs, OTAs, reservation systems or payment gateways.
• Experience building or leading a forward deployed, solutions or integrations engineering team.
• Kafka / Redpanda, OpenSearch / Elasticsearch, pgvector, Terraform.
• Experience in the GCC markets, and Arabic language skills.

YOUR FIRST 90 DAYS

• First 30 days: learn the platform and our live integrations, ship your first production change, and meet our key partners.
• By 60 days: own at least one integration end to end, and agree the shared integration standards (auth, webhooks, idempotency, testing) with the team.
• By 90 days: have the FDE hiring plan running, a delivery rhythm the team and partners trust, and clear reliability metrics for the integration layer.

WHY JOIN ESTAIE

• Build and shape a new team from the start, at the frontier of AI-native hospitality.
• Work directly with a founding team from Careem, Grab and Deutsche Telekom who value clarity, velocity and ownership.
• Real-world complexity: partners and systems across the global hospitality ecosystem, with your work reaching production fast.
• Flat, product-driven culture with strong engineering autonomy and end-to-end ownership.
• Competitive compensation and founding-team ESOP potential.
• Remote-first, or hybrid from our hubs in Dubai and Riyadh.

Luna Media is redefining how digital advertising works, connecting premium supply with smart demand across Mobile (in-app) and CTV through cutting-edge programmatic technology, AI-driven optimization, and real-time bidding. We move fast, think big, and build partnerships that last.

We’re looking for a Programmatic Account Manager to join our team. In this role, you’ll own strategic partner relationships while overseeing the technical operations, performance optimization, and day-to-day management of integrations and traffic flows. This is a position for someone who brings both a commercial mindset and deep technical fluency, someone who can lead partner conversations at a strategic level while still diving into the details when it counts.

Responsibilities: 

1. Ownership

   Be the analytics counterpart for a product domain 1:1 chat, content packs, negotiations, live streaming — you become the person PMs and engineers come to for any number in that area, and the person accountable when it's wrong.

2. Experiments

   Run A/B tests on product features, end to end Turn a product hypothesis into a test: primary and secondary metrics, the minimum effect worth detecting, and the audience. Confirm the population split and assignment events are genuinely correct before trusting the readout. Monitor it while it runs, then deliver a clear ship / don't-ship call and the reasoning behind it. This is a large part of the job, not an occasional project.

3. Pipelines

   Build and maintain the datasets behind your domain Write production transformations as SQL and YAML pipeline config, with freshness, uniqueness and validity checks. Your work goes through code review like any engineer's.

4. Events

   Specify instrumentation before it's built Write the BI event spec for new features across Android, iOS and Web; then verify after release that events actually fire the way the spec said, and chase the gaps when they don't.

5. Dashboards

   Own dashboards and the models under them

   Including retiring the ones nobody opens. A dashboard with no reader is a cost, not an asset.

6. Analysis

   Investigate what moved and why Revenue and conversion anomalies, feature performance, behavioural questions from PMs. Present findings to people who will act on them.

7. Incidents Size production incidents under time pressure When something breaks, you're asked how many users were affected and for how long — quickly, and precisely enough to defend the number when engineering disagrees with it.
8. Cost Keep query and pipeline cost honest Partitioning, clustering, and knowing why a query scans what it scans. Warehouse capacity is shared and finite; an expensive pipeline is everyone's problem.

Requirements:

• Advanced SQL, including window functions and multi-source joins — and the ability to reason about what a query costs, not only whether it returns.
• A strong experimentation background. Hypothesis testing, confidence intervals, power and minimum detectable effect — and the failure modes: peeking at a running test, multiple comparisons, hunting for a segment where the result works. You should also be the kind of person who checks that the experiment itself is sound before trusting its numbers.
• 3+ years as a product or data analyst on consumer products, with real exposure to both mobile and web.
• Critical use of AI analytics tooling. We use an internal Claude-based layer over BigQuery heavily. We want someone who checks what it produces before passing it on.
• Comfort shipping code: git, merge requests, reading and reviewing someone else's SQL. You'll write production pipeline code, not only notebooks and queries.
• Working knowledge of product event tracking: what a well-specified event looks like, and why the same event behaves differently across platforms.
• English at B1 or above. You'll write specifications that engineers build from and present findings to product stakeholders, so clear written English matters more than fluent speech.

Strong advantage

• BigQuery specifically — partitioned tables, clustering, slot-based pricing.
• Airflow, dbt, or another orchestrated transformation framework.
• Having been the analyst on a production incident, not only in the post-mortem.

Nice to have

• Python with the usual statistical libraries — pandas, scipy, stats models.
• A BI tool such as Looker, Tableau, or Power BI — having built the models and dashboards, not only read them. We use Looker today but are moving off it, so the particular tool matters much less than having done the work in one.
• Data quality tooling such as Soda or Great Expectations.
• Experience in social, live-streaming, gaming or another engagement-driven consumer product.
