Let’s Start With a Hello 👋

At Azura Infinity, we’re looking for a Global Talent Acquisition Manager who knows that great recruitment starts long before a vacancy is posted.

We work across global markets, different GEOs, cultures and talent landscapes — and we’re looking for someone who can turn an unfamiliar market into a clear talent map and a challenging vacancy into a sourcing strategy.

Someone who doesn’t stop at:

“There are no candidates.”

But asks:

Where are they? Which companies are they working for? Where do they communicate? Who knows them? What would make them talk to us? And what haven’t we tried yet?

Because for us, Talent Acquisition isn’t about spending more on endless job advertising.

It’s about knowing the market well enough to know where to look.

What You’ll Be Doing 

Own global talent searches.
Work across international markets and GEOs, adapting your sourcing approach to each market rather than applying one recruitment strategy everywhere.

Go deep into market mapping.
Identify donor companies, key professionals, competitors, team structures, local talent clusters, communities, salary benchmarks and talent movement.

Know where to start.
When a new role or GEO lands on your desk, your first question shouldn’t be “Where can I post it?” but “Where does this talent actually sit?”

Build sourcing strategies from scratch.
Define target companies, candidate profiles, sourcing channels, outreach approaches and market entry points before investing time and budget into advertising.

Go far beyond LinkedIn.
Explore local platforms, niche communities, professional networks, industry events, referrals, social media, databases and unconventional sourcing channels.

Hunt people who aren’t job-hunting.
Proactively identify and engage passive talent, including niche, Senior, Head and executive-level professionals.

Conduct interviews that go beyond the CV.
Dig into real achievements, expertise, decision-making, motivation, market knowledge and career logic — understanding the person behind the profile.

Build warm global talent pools.
Strong candidates shouldn't disappear just because there isn’t a suitable vacancy today. Build relationships that give us a head start when tomorrow’s hiring needs appear.

Bring Talent Intelligence to the business.
Research compensation, candidate expectations, competitor activity, talent availability and market trends — and turn those insights into actionable recommendations.

Understand what actually works.
Analyse sourcing channels and recruitment funnels instead of measuring success by the number of CVs generated.

Challenge the search before challenging the market.
Before concluding that “there are no candidates”, understand what was searched, where, how, with which message — and what the market data is actually telling us.

Make every search smarter than the previous one.
Build market maps, donor-company lists, sourcing playbooks and channel libraries so we accumulate knowledge instead of starting every vacancy from zero.

What We’re Looking For 

Must-have:

• Strong iGaming / Betting expertise — you already understand the industry, its ecosystem, key players and talent landscape.
• Proven experience in Global Talent Acquisition / International Recruitment across multiple GEOs.
• Strong hands-on headhunting and executive search experience.
• Experience recruiting niche, senior and hard-to-find professionals.
• Ability to independently research and map a new talent market from scratch.
• Experience with Talent Intelligence, competitor research and donor-company mapping.
• Strong sourcing expertise beyond traditional LinkedIn searches and job boards.
• Ability to conduct deep, structured and competency-based interviews.
• Strong analytical mindset and understanding of recruitment funnels, sourcing efficiency and market response.
• Ability to build and maintain an international professional network and warm talent pools.
• English B2+/C1 — a must. You’ll use English daily with candidates and stakeholders across global market

About the work

We build and maintain industry intelligence databases - organizations, people, products and their relationships across sectors such as HealthTech, QuantumTech, LegalTech and wellness, covering multiple regions. Every one of them starts as messy public data and has to end up as a clean, deduplicated, verifiable dataset that analysts and downstream products can rely on.

That means the hard problems here are not "write a scraper". They are: how do you know two records are the same organization? How do you prove where a field came from six months later? How do you re-run a collection over a source that changed its markup, without corrupting what you already have?

You will work directly with the Head of Data Science and a team of AI and data engineers.

What you will do
 

• Build and own collection pipelines over public web sources - structured, semi-structured and awkward
• Design the enrichment layer: normalization, deduplication, entity resolution, confidence scoring
• Keep provenance on every field, so any value can be traced back to its source and date
• Use LLMs where they genuinely help - extraction from unstructured text, classification, taxonomy assignment - and know where they don't
• Take datasets from one-off collection to scheduled, monitored, re-runnable pipelines
• Define and enforce quality checks: coverage, freshness, duplicate rate, field completeness

What we're looking for

Both levels
 

• Strong Python - you write services and pipelines, not notebooks
• Real production scraping experience: sessions, rate limits, retries, blocks, anti-bot, JS-rendered pages, APIs that are not documented
• SQL and PostgreSQL beyond CRUD - indexing, query plans, schema design
• Practical experience with LLM APIs for extraction and classification, including how you validate their output
• Data quality instinct: you check what you collected before you hand it over

Additionally for the Senior opening
 

• You have owned a data platform, not just tasks on one - orchestration, scheduling, monitoring, backfills
• Experience with entity resolution or record linkage across sources that disagree with each other
• Airflow, Dagster or Prefect in production
• You have set the standards other people then worked to: schemas, conventions, review

Nice to have
 

• Docker and CI/CD
• Knowledge graphs, ontologies, or taxonomy design
• Vector search and RAG pipelines
• OSINT methodology and source verification
• Experience with data licensing or compliance constraints on public-web collection

How we hire
 

1. Intro call - 30 minutes, mutual fit and what you've actually built
2. Paid proof task - a real, bounded piece of our work. Paid at market rate, roughly 4 hours. We are not asking anyone to work for free
3. Technical review - we go through your solution together: your trade-offs, what you'd do with more time, what you'd do differently at ten times the volume
4. Offer - band determined by the level you land at, not by the title you applied under

We evaluate the proof task on judgment, not polish. Reproducibility, honest handling of edge cases, and clear reasoning about what you chose not to do count for more than a clever one-liner.
What we care about

Two things, mostly.

You question your own data. The engineers who work out well here are the ones who notice that a source silently changed its schema, that a "97% match rate" is hiding a systematic bias, that a field is populated but wrong. Volume without verification is worth nothing to us.

You explain your reasoning. Much of this work involves judgment calls that nobody can check quickly - which record wins a merge, what confidence threshold to use, when to stop enriching. We need those decisions written down and defensible, not buried in a script.

To apply: send your CV plus one short paragraph on the hardest data collection or deduplication problem you have solved, and what you got wrong on the way.

At P2Bid, we build multiplayer games where every game mechanic is powered by a fast, reliable, and scalable backend.
 

We're looking for a Senior Python Developer with 5+ years of commercial Python experience, including 3+ years building asynchronous backend services under real production load.
 

About the role:

We're looking for an engineer who goes beyond implementation and takes ownership of technical decisions.

You'll be responsible for designing and evolving core backend services, owning critical parts of the system, reviewing code, and helping shape the technical direction of the product. We value engineers who think about reliability, scalability, maintainability, and long-term architecture—not just delivering features.
 

Requirements

• 5+ years of commercial Python development experience.
• 3+ years building high-load asynchronous backend services.
• Strong knowledge of Python 3.11+, async/await, the event loop, and asynchronous programming principles.
• Hands-on experience with asynchronous web frameworks such as FastAPI, Starlette, aiohttp, Litestar, or similar.
• Deep understanding of asyncio: gather, TaskGroup, task cancellation, timeouts, backpressure, and concurrency patterns. You understand why a silently failed background task is a production incident.
• Strong typing as a standard development practice. Experience with mypy or pyright, Protocols, Generics, and modern Python typing.
• Excellent SQL skills, including JOINs, indexes, transactions, and extensive experience with PostgreSQL.
• Strong understanding of PostgreSQL locking mechanisms (FOR UPDATE, SKIP LOCKED), transaction isolation levels, deadlocks, and query execution plans.
• Experience with SQLAlchemy (ORM or Core) or another mature ORM.
• Confident writing automated tests with pytest, fixtures, parametrization, and dependency mocking.
• Experience working with Docker, Git, and code reviews through Merge/Pull Requests.
• Production experience with message brokers such as Kafka, RabbitMQ, NATS, or similar. You've debugged real production issues—not just studied the concepts.
• Practical experience building distributed systems, including at-least-once delivery, idempotency, deduplication, and understanding why exactly-once delivery is not achievable over the network.
• Experience working with business-critical domains such as payments, billing, accounting, order management, inventory, or any system where mistakes have financial consequences.
• Strong understanding of failure scenarios. For example, you know how to handle cases where a request was sent but no response was received—and why a naive retry may be worse than a failure.
• Ability to perform meaningful code reviews, focusing on architecture, reliability, maintainability, and engineering quality—not just code style.
• English sufficient for reading technical documentation, writing code comments, and technical documentation. Spoken English is a plus but not required.
   

Tech Stack

• Python 3.12
• FastAPI
• PostgreSQL
• MongoDB
• NATS / JetStream
• Docker
• Kubernetes

We also use dishka (dependency injection), adaptix (mapping), FastStream (message broker abstraction), ty (typing), and uv (dependency management). You don't need prior experience with these libraries—they're based on familiar concepts and are easy to learn. During interviews, we focus on your understanding of asynchronous programming, SQL, distributed systems, and engineering trade-offs, not on knowledge of specific libraries.
 

If you meet most of the requirements, we'd love to hear from you—even if some technologies in our stack are new to you.

Sovrano AI, SL is a Barcelona company selling verified European expert capacity to frontier AI labs, robotics companies and enterprise AI teams. A network of 400,000 or more professionals, 100 or more partner universities across Europe, EFMD certification, 23 languages, a funding round led by b2venture, and a proprietary benchmark in EuroExec.

The job

You build the interview agent: a real time voice system that talks to candidates, listens, and holds a conversation that has to feel right on the first attempt. Speech to text on the way in, an LLM in the middle, text to speech on the way out, and a latency budget measured in hundreds of milliseconds. Someone interrupts halfway through a sentence and the agent handles it the way a person would. A model stalls, and the failure sounds like a pause rather than a crash.

Real time voice is unforgiving in a way that ordinary product work is not. There is no loading spinner. It either feels like a conversation or it does not, and the difference is measured in milliseconds you have to go and find.

The interface is as much of the product as the model behind it. You lead on the UI, and you care how it feels rather than only whether it works.
 

The stack

The agent is Python on LiveKit, with streaming speech to text and streaming text to speech either side of an LLM. The interface and the wider platform are Node.js, TypeScript and React, on PostgreSQL and Google Cloud. You work across both halves.
 

You own

• The interview agent end to end: the real time voice pipeline, the model integration, and the prompt and evaluation loop behind it
• Latency, interruption, endpointing, turn taking, and what happens when a model or a network stalls mid sentence
• The candidate facing interface, from interaction design through to shipped frontend
• Model quality, measured rather than asserted. Eval datasets, regression testing on prompt changes, and knowing whether a change made the conversation better or only different
• Integrations that bring the agent, its output and its evidence into the rest of the platform

The experience we require
 

• Five or more years building production software, full stack, with strong frontend depth in TypeScript and React
• Real time audio shipped to production. Streaming speech to text and text to speech, WebRTC or an equivalent transport, and the work that comes with them: voice activity detection, endpointing, turn taking and barge in
• LLM APIs in production. Streaming, tool calling, structured output, first token latency, cost, and what the product does when the model answers wrongly in front of a user
• You measure latency rather than estimate it. A p50 and a p95 you can quote per stage of the pipeline, and tracing good enough to say which hop is the expensive one
• Genuine UI and UX judgement. You take a rough idea to a designed, shipped interface and can explain the choices
• AI native. You already work with AI tools daily and build what you need without being shown how
• English at B2 or above
   

Also worth having

• LiveKit, or another real time agent framework run in production
• A view on the providers at each stage and why: Deepgram, AssemblyAI or Whisper for speech to text, ElevenLabs or Cartesia for speech out
• Speech to speech models, OpenAI Realtime or Gemini Live, and a position on when collapsing the pipeline is worth the control you give up
• Async Python and FastAPI
• Evaluation tooling: Langfuse, LangSmith, or something you built yourself
• Voice treated as personal data: redaction, retention and access control

A network of 400,000 or more professionals, 100 or more partner universities across Europe, EFMD certification, 23 languages, a funding round led by b2venture, and a proprietary benchmark in EuroExec.
 

The job

You are the engineering lead on the platform, working alongside the CTO every day. Platform architecture, scaling, infrastructure and data are yours. When a query gets slow, when a service will not hold the next order of magnitude, when a feature needs to be designed before it can be built, that is your call to make.
 

This is roughly 70 percent building and 30 percent raising the standard of everyone else's work: reviewing pull requests, setting the code quality bar, unblocking teammates and making decisions that stop being reversible three months later.
 

You own

• Platform architecture and the scaling path, from schema and query performance to infrastructure and cost
• Delivery of the harder platform features end to end, from design through production
• Code quality across the codebase: review standards, testing, what ships and what does not
• Technical decisions made with the CTO, and the ones made on your own when the CTO is not in the room
• The engineers around you getting better, through review, pairing and design conversations
   

The experience we require

• Seven or more years building production software, with real time spent on systems that grew past their first architecture
• Depth in relational data: schema design, query optimisation, and diagnosing performance from first principles rather than by guessing
• Cloud infrastructure and CI/CD owned in production, not consumed as a service someone else runs
• A track record of raising other engineers' work through code review and design feedback
• AI native. You already work with AI coding tools daily and build the tooling you need without being shown how
• English at B2 or above
   

Also worth having

• Experience in an AI or data platform company
• Time as a founding or first senior engineer somewhere
• Comfort moving across the stack when the work demands it
