Join the STL USA team.

Would you like to join the STL USA team?

We have three opportunities to join the STL USA team. We’re currently recruiting for two trainers and a back office role at STL USA as we continue to grow across the country.



STL USA has been operating in the USA since 2015, with two main training facilities located in Texas and Iowa. Part of the Safety Technology group of companies headquartered in the UK and with operations across Europe, STL USA extends the knowledge and experience built up over 20 years in wind energy delivering training and safety solutions for the largest global companies. STL USA is exclusively focussed on delivering GWO training across a range of standards to technicians working across the country. Thousands of techs have passed through STL USA training courses and the company ambition is to to grow rapidly in the coming years in line with the huge growth the wind sector is experiencing in the USA.


Job description: GWO Training Instructor x2

Location: Texas, flexible

Subject to an initial training period of 2-3 months depending on competency and experience. The training instructor will be expected to deliver company training programmes within the specified training procedures and accredited standards, for GWO. This includes a number of theory, discussion and practical elements across the modules; fire awareness, first aid, manual handling and working at height. The nature of GWO training is very practical and the instructor is therefore required to be able to demonstrate a number of course elements in a simulated wind turbine environment, therefore requiring a level of climbing competency and fitness.

The key tasks include:

  • Carry out company and Accredited training programmes and provision of training procedures as required.
  • Complete training documentation and records as required
  • Develop and improve training equipment and facilities as appropriate in line with the Technical Director.
  • Maintain training facilities and training equipment
  • Carry out product inspections, maintenance and re-certification of products.
  • Assist with the organisation and participation in exhibitions when required
  • Liaise with partner companies, specialist suppliers and organisations as required.
  • Implement effective health and safety including, writing, updating and following risk assessments, safe systems of work and company procedures.
  • Act as Fire Marshalls and First Aiders, and implement the company Health and Safety practices at all times.
  • Provide effective support and communication to customers and other team members especially internal sales administration, sales and directors.
  • Maintain company systems and procedures including enquiries, quotations and quality and training procedures. Auditing and review of customer feedback.
  • Carry out other duties as requested by the company such as site inspections, onsite training, overseas training and audits.


The role would suit somebody already working in wind energy, ideally in a supervisory role, safety role or with suitable turbine experience. GWO certifications are an advantage but anyone with a teaching/training background and the relevant working at height experience would be considered. It goes without saying the person must be comfortable working at height.

Salary and benefits: To be discussed (in line with market rates)

The state of wind energy in lockdown.

With many of us in wind energy in lockdown this weeks post speculates on where we’re heading.


So what is the state of wind energy in lockdown? So let’s get this out of the way the wind is still blowing, turbines are still turning and I have to say that most people I’m speaking with are continuing to operate, albeit under strict distancing guidelines. Of course a lot of us are classed as essential workers so we’ve had to adapt quickly to this situation. For STL USA in particular this has meant moving courses to an onsite format where we can but of course not every customer has access to a turbine or tower to conduct a training course.

On this note I’d like to give a major shout out to the guys at Cotech who’ve let us use their training facility in Houston whilst ours is shut.

The GWO have played their part by quickly developing a new partial online course for Basic Safety training refreshers. This course allows for 100% delivery online over the space of a few days via a virtual classroom format. The course is built around interaction and requires both instructors and technicians to demonstrate a series of actions within the curriculum as well as theory elements to gain the 6 month interim accreditation.

This is an exciting development for STL USA as we’ve been eagerly awaiting the launch of an online, blended course format to broaden our course offering across the USA. We’ve also spent some of our lockdown time accelerating our plans to bring the GWO ART course to the USA. This is something we’re particularly keen to have sit alongside our standard GWO safety training courses.

Our wider outlook for wind is still very positive despite the current lockdown. Wind energy is proving itself to be a cost effective source of energy generation and with numerous new developments in the pipeline including the major offshore farms we still believe well end 2020 in an upbeat mood.

The second half of the year will see us looking further afield from our traditional mid-West base in the “wind corridor”. The next stage of our growth will be focussed on the offshore market, our longer term goal is to begin delivering GWO Sea Survival from a strategically located training center by the end of 2020. This is about 4-6 months behind our initial plan but hey Covid-19 came along so we hope you’ll forgive us.

All that’s left for us to do is say a big thank you to all our people who have worked tirelessly during this difficult time, for our clients patience and to the wider wind community for hanging in there.


If you’d like to talk about how we can support you GWO training get in touch.

“The course was great, we actually got to apply what we learned. The instructors Ben and Adrian made the class very enjoyable”.

“All the subjects covered were good. The instructors were great at explaining all the technical points and made the course very enjoyable”.

From Canada to New Mexico, STL USA’s Ben Williams cycles for cancer research charity

STL’s very own Ben Williams cycled from Canada to New Mexico raising funds for Cancer research a charity close to his heart.

When Ben Williams, Safety Technology USA’s training director and head of GWO training, walked into the office and said he wanted to take 6 weeks off work to go cycling he received a few quizzical looks from his colleagues. But, after he’d explained he was taking on Tour Divide Ultra-Cycling Challenge and that he was doing it in aid of vital cancer research, the company quickly mobilised efforts to help him on his way.


The Tour Divide Ultra-Cycling Challenge which is described as “the world’s longest and toughest off-pavement cycle route” climbs nearly 200,000 feet – the equivalent of summiting Mount Everest from sea-level seven times. Along the route Ben endured the off-road trails and passes of the Rocky Mountains, gruelling hill climbs, stretches of barren desert and extreme heat as well as the daily physical and mental challenges associated with ultra-mountain biking of this type. Solo and unsupported with just a tent, bike and GPS this complex route inhabited by locals such as grizzly bears and mountain lions, adding another dimension to the daily challenge. Undeterred Ben made the most of this fantastic opportunity.

“What made the whole thing so amazing was the people I met along the way. If it wasn’t for the American people and their kindness the challenge would have been a whole lot harder.”

Ben decided to take part when someone truly dear and amazing to him suffered pain and discomfort on a level he could not comprehend.  As a tribute he wanted to put himself through pain and discomfort for about a month to raise funds to continue research and help prevent others from experiencing the same level of pain.

Lynne Eagles, Cancer Research UK’s local fundraising manager for Wales, said: “We are absolutely delighted that Ben has decided to attempt such an incredible and gruelling challenge to raise vital funds for Cancer Research UK.

“Ben had an amazing experience and we can’t thank him enough for his support. We want to wish him the very best for his journey. Cancer Research UK has made enormous progress in the fight against cancer. However, we have only been able to do this thanks to the dedication and commitment of our volunteers and supporters, without whom we would not be able to fund our research.”


Ben Williams Safety Technology USA

Ben was invited to speak by Cancer research about his epic ride at a recent event.

For those who have felt inspired by Ben’s challenge, why not sign up to a cycling challenge of your own? Maybe start with something a little more easy to manage though!!
