Hello everyone and welcome to Open Search Network LTD. 

My name is Aldo, I am an Italian Headhunter with a great passion for technology. I can consider myself as an addict to all the social channels from Linkedin to Twitter, but not in a “wasting time” way. I love socials for the opportunities that they can give you and for their revolutionary power. I have graduated in Italy in Milan at the Bocconi University in Business Administration and since 2007, when I was employed at Michael Page, I have devoted my career to headhunting. 

In 2013, thanks to my adventurous spirit (I love backpacking around the world) and my baggage of professional experience in headhunting I decided to start my own business, Open Search Network LTD.

What I wanted to do with OSN was not a common headhunting agency. The market is already full of them.
I wanted something different, a headhunting company able to deliver an outstanding service. To do this, you need to focus your work on a specific job market and on a specific profile. A competitive business needs a clear and straight view, there are no doubts.

For me and for my business, these starting points were two, Italy and the Digital and Data field. Why?

Easy, firstly, I am Italian and I know how Italian professionals work and how Italian market is developing. Secondly, because my expertise is that of Data science. In the beginning, I was the only member of my startup and my own house was my only office, sometimes working from London and sometimes from Italy. Today, my business has grown up and we are a team of six people with a real and well-functioning office based in London able to provide the best headhunting service in the field of Data.

Hello, I am Michela and thank you for coming to see my personal story. 

As all the other member of Open Search, I am Italian but I live and work in London since 2011. 

Here, I cover the role of Manager since I was one of the first members to join Aldo in this start-up. Anyway, I still work as a headhunter. In fact, I help the other headhunters in their selections of profiles, giving them advice and listening to their issues.

I have studied for a Bachelor's Degree in Social Science at Università Cattolica del Sacro Cuore in Milan and since then I have always worked in H&R. For a few years, I have worked in Italy, anyway, thanks to my experience in Page Personnel, I have decided to move to London. The reason? I wanted to develop an international career.

Here I have been HR Consultant and a business developer for the financial and accounting division for nearly two years. This work experience finished in 2011 when I have decided to come to London in order to develop my international career and learn English. In London, I have joined Executive Surf where I have started to focus my work on the Italian recruiting market. 

Later, influenced by my love for new technologies and for the people that develop and create this advanced world I joined Open Search Network in 2015. Since then, I have brought to Open Search my positive attitude and my belief in people’s honesty and goodwill.

Alessia Cavaliere

Welcome on my personal page. I am Alessia headhunter at Open Search Network.   work in human resources since 2016 after an academic path in criminal studies. 

At first sight, these two fields seem to be very different. Anyway, skills like interrogation techniques and the ability to read non-verbal expressions are essential for my position.

I came to London in 2017 and, in the same year, I joined Open Search Network. Here, my skills and experience were immediately appreciated.

Why? Probably because for me a headhunter is not a machine that selects candidates,  but a friend able to suggest and advice people. With my job, I want to start a perfect long-standing relation between people and companies. A relationship that can be fruitful for both.

That is why I always keep in touch with candidates. After they start their new job, I always want to know their first impressions, their point of view and if it matches or not their own expectations. 

As a headhunter of Open Search Network focused on data profiles, I always go the extra mile thanks to my great passion for all that it is technological. I crave for all the latest technological innovations and brand-new devices ( I am Apple addicted). Moreover, I followed courses about data science in order to have a professional knowledge of this field.

In conclusion, I can say that my job at Open Search Network is distinguished by these two main features: confidence and passion for technology.

Welcome to my profile, my name is Annarita I am one of the headhunters here at Open Search Network LTD. 

I have arrived in Open Search in 2017 where I have brought dedication and spirit of enterprise, two features that I have nurtured during my life and my career, in particular during my experience in the Italian Army. 

My educational background in cognitive and criminal studies together with the incredible experience in the army developed in me a particular interest in people’s happiness. What I try to do with my job at Open Search is to fulfil part of this happiness. 

This is why I want to know candidates in every aspect of their life, I want to know what they like, their expectations and what stands behind their CVs or their cover letters. I try to understand the person, not his résumé. 

I follow all the applicants from the beginning to the end of the selection process, furthermore, I try to guide them on their path, never leaving them alone. I know how it is hard to find the right job and how it is hard to be alone in doing it. I am a headhunter and this is my mission.

As I mentioned, one of the secrets of my job is to understand people, this means that I need to know also their field of expertise and their subjects. 

Through my passion and curiosity for the world that stands behind the technology, I have started to build a professional knowledge of data science. Following numerous courses, I have created a strong knowledge of this fascinating subject. Now, my headhunting service here at Open Search network is mainly focused on the research of Data Scientists.

I have recruited entire teams and hard to find IT professionals across Europe since the beginning of my recruitment career.

Hi, I am Benedetta and thank you for visiting my profile.

I am a friendly headhunter specialized in the Data Science field, here at Open Search Network. I am always keen to speak with outstanding specialists in order to understand their needs and, together, to find the best career solutions. My professionalism, honesty and transparency are really appreciated from both my clients and candidates and this is what makes me proud about doing my job.

Now let me tell you something about my past.

I have an educational background in economics and in human resources management and I gained my MSc from the University of Florence. I have started working in recruitment since my graduation in 2015. My first experiences have been 2 internships in Italy. The first one at Manpower Italia and the other one in the Targetti SpA’s Human Resource offices.  

During the summer 2016 I moved to London because I felt the need to gain international experience and, before starting my career in Open Search Network, I worked as Recruitment Specialist at SEC Recruitment, one of the European leading providers of talent acquisition services for the pharmaceutical market.

Through all these experiences I had the opportunity to build up my recruitment and HR management expertise and a lot of other skills that I am always applying, not only within the working environment. Without mentioning the amazing people that I met that are still good friends of mine. Now that you know me a bit more, it would be great if you want to get in contact with me. Even for a simple career/opportunity advice.

I am looking forward to hearing from you soon.

Welcome to my profile! My name is Marta, I am from Milan and I have joined Open Search Network in 2018. I graduated in Law, then took an M.Sc. in Human Resources in 2015 and since then I have always been working in recruitment, with a touch of business development at times. My graduation thesis was based on interviews with families who married with mixed marriage rite. That was already a clue that I would work in a job based on researches and interviews!

Now I live between Milan and London, and in OSN I work in the Data Strategy Team as a headhunter specialized in Cybersecurity. I speak to candidates every day and my aim is to understand their needs, what is important for them and explore together the best career path.

In this work, I have learned that active listening is key. Being able to hear what people are really saying makes me more effective in supporting them in their job search. My mission with every candidate is being able to create the best match with the role while making sure that all the right circumstances are in place for you to start a comfortable and long-lasting relationship with your new colleagues.

Welcome to my profile. My name is Silvia and I am from Turin. I am an Italian headhunter living in London and I have joined Open Search Network in 2018 where I am specialised in Data Engineering field. 

I have a Master’s Degree in Psychology and I did various internships in both clinical and organizational psychology. Later, I worked in the HR field for a few years and I run out my own fashion business and brand. 
These two different work experiences reflect two different parts of my being. On one hand,  HR helped me to organize and prioritize, by stimulating my logical mind side. On the other hand, to work in fashion allowed me to express my creativity and improve my networking skills. 

In OSN the greatest challenge for me is to be able to respect our company’s deadlines and at the same time find the right space to take care of my candidates. 

Psychology remains one of my biggest passion and I am glad to use my skills and knowledge by helping candidates to find the best opportunities in line with their wishes. I love following them during the selection process, making them feeling at easy and offering an active listening and support for whatever request, doubt or need. It is a teamwork, in which I do celebrate with my candidates their success and I comfort them in failures, obstacles, changes and frustrations; which are part of this job and life in general.
