About Me

Engineers collaborate on designs with blueprints and laptops in a modern office setting.
Who I Am

I’m Hiren Dhangar, an Engineering Manager and Freelance Engineering Consultant specialising in complex, safety-critical environments across the nuclear and maritime sectors. I began my career in the Civil Service, supporting government defence programmes and influencing policy at a national level. That foundation gave me a deep understanding of how major engineering decisions are made — the strategic, regulatory and risk-driven thinking that sits behind them.

A strategic engineer with experience across government, industry and safety-critical programmes.

Transitioning into industry strengthened my technical capability and leadership experience. I’ve led multidisciplinary engineering teams, owned key systems, and delivered projects where quality, reliability and structure are non-negotiable. This combination of policy insight and hands-on engineering execution enables me to bring a balanced, systems-led perspective to every project — helping clients reduce risk, improve performance and move work forward with clarity and confidence.

What I Do & How I Help Clients

Through HDEC (HD Engineering Consultancy), I help engineering teams and organisations streamline their systems, strengthen their processes and deliver high-quality projects with clarity and confidence. My specialist areas include process optimisation, systems design, requirements capture, risk management and engineering leadership support.

Beyond consultancy delivery, I also support people — not just projects. I provide coaching and mentoring to both current and aspiring engineers, offering structured guidance on career development, interview preparation, application reviews and building the professional mindset needed to excel in demanding engineering environments. My approach is practical, honest and rooted in real industry experience.

I also create engineering content designed to educate, simplify and inspire. From technical explainers and templates to professional writing, articles and LinkedIn content, I help individuals and organisations communicate their ideas clearly and position themselves as credible, modern engineering professionals.
Clients and mentees work with me because I combine deep technical knowledge with the ability to communicate complex ideas simply — helping them solve problems faster, operate more effectively and achieve meaningful progression in their work and careers.

Professional Integrity & Ethical Standards

I take professional integrity extremely seriously. All consultancy, coaching and content creation services I provide are fully independent and conducted in a way that respects my current and former employment contracts. I never disclose confidential or sensitive information, and I do not use proprietary knowledge, internal materials or privileged insights from any organisation I have worked with.

My work is built on honesty, discretion and trust. I only share experience that is publicly available, personally developed or universally applicable across the engineering profession. Whether I’m supporting a client, mentoring an aspiring engineer or creating content, I operate with the highest ethical standards to ensure that my contributions remain responsible, impartial and fully compliant with all professional obligations.
