Job Offering Company Introduction
Energy Solutions (Pvt.) Limited (ESL) is a Karachi-based company rooted in power generation services, with a reputation built on technical depth and customer commitment. Founded with the mission to guide clients through equipment selection, installation, commissioning, operation, and maintenance of power generation systems from 1 kVA to 2,500 kVA, ESL strives consistently “to do more than what is said and deliver more than what is promised” (eslpk.com).
Over the years, professionals with a cumulative experience of more than 250 years in power generation have led ESL, allowing it to become a trusted provider of premium diesel and lean-burn gas generators, partnering with global names like Aksa (Turkey) and Cummins Gas (UK) (eslpk.com). Beyond generators, ESL delivers solar and renewable energy solutions, reflecting its ambition to be a holistic energy provider under the banner: “One Stop Shop” (eslpk.com).
With over 8,000 generators and solar units installed, more than 500 MW of power supplied, and 2,000-plus maintenance contracts across Pakistan, ESL supports a wide array of industrial, commercial, and institutional clients. Its national presence is backed by ISO certification for quality (ISO 9001), environmental management (ISO 14001), and occupational health and safety (ISO 45001) (eslpk.com, esl.petrolsolutions.com).
ESL’s commitment to corporate responsibility goes beyond business. Through programs like “Living Responsibility” and the “ESL Green Initiative,” the firm plants a tree for every generator or solar installation and dedicates training hours for professionals and students involved (esl.petrolsolutions.com). With offices in Karachi, Lahore, and Islamabad, ESL provides extensive regional coverage, ensuring quality execution and after-sales support across Pakistan (eslpk.com).
Brands and clients across industries—from Coca-Cola, Telenor, and Allied Bank to healthcare and textile giants—have relied on ESL’s dependable power solutions (eslpk.com). Their enduring message is clear: ESL is not just a supplier; it builds lifelong partnerships by delivering reliability, service, and more than what is expected.
Job description
Energy Solutions (Pvt.) Limited is currently seeking Trainee Sales Engineers in the fields of Electrical, Electronics, or Mechanical engineering. These full-time positions are based at ESL’s Karachi office and are tailored for fresh graduates who are eager to step into the power generation sector and grow through hands-on learning and field exposure.
In this role, you will work in close proximity with senior sales professionals to understand the technical and commercial aspects of the energy solutions market. You will support business development by assisting in customer interactions, proposal preparation, and project scoping. You will also accompany senior staff on visits to customer premises to gather requirements for diesel generators, gas generators, and solar energy systems. You’ll attend meetings with clients to understand their energy needs, from load capacity, environmental considerations, to redundancy planning.
You’ll gain exposure to the full lifecycle of an energy project—from initial discussions to quoting, bidding, technical clarifications, and closing deals. Your support could involve tailoring proposals based on site requirements, load calculations, equipment selection, and generating quotes in collaboration with the commercial team.
Beyond quotes, you’ll learn how ESL handles project commissioning, synchronizing setups, and operation and maintenance services. You’ll observe installation procedures, learning how synchronizing generators with utility systems or configuring backup power is done safely. You’ll also get familiar with service contracts, maintenance scheduling, and how ESL ensures uptime through swift after-sales response.
Field assignments will bring you face-to-face with generators of different capacities, solar EPC sites, project handovers, and synchronizing operations. You’ll understand how to size systems, determine fuel requirements, and support load-sharing units. Understanding the interplay between technical components and commercial needs will enhance your understanding of power solutions in real-life environments.
You’ll aid in preparing client presentations that explain technology, pricing, and value. Maintaining professionalism and clarity while addressing client questions is critical.
At the same time, you’ll support marketing with content generation—case studies, project snippets, and technical product brochures. Creating promotional materials helps build your ability to translate technical content into client-accessible formats.
Throughout, you’ll document your observations in CRM systems, prepare reports, log client discussions, and track follow-up actions. Familiarity with inquiries through digital tools or Excel becomes essential.
Career progression includes stepping into project support roles—supporting a site handover or tracking project milestones. The more you engage in real situations, the clearer your path in technical sales or project management becomes.
The Trainee role may span 6 to 12 months, preparing you for the next role: Assistant, Deputy, or Manager – Sales Engineer (Busways). In advanced positions, you’ll handle clients directly, manage pipelines, negotiate contracts, and lead projects in power distribution (busway systems).
Through mentorship and fieldwork, you’ll build credible foundations in both technical energy systems and client relationships, positioning you to advance within ESL’s team of solution-driven professionals.
Eligibility criteria
To apply for the Trainee Sales Engineer role, candidates must meet the following criteria:
You must be a recent graduate with a Bachelor’s degree in Electrical, Electronics, or Mechanical Engineering from an accredited institution. Graduating not earlier than two years ago is preferred, keeping the role fresh and focused on development.
You should demonstrate curiosity about industrial power systems—fuel-based generators, solar installations, load sharing, and backup power configurations. Academics are valued, but so is your willingness to learn field operations, generator configurations, and solar sizing.
Strong communication skills are essential; you’ll engage in client presentations, team collaborations, and technical documentation. Speaking clearly, asking questions, and articulating ideas confidently will help your performance as a trainee.
You should also be comfortable with basic engineering tools—like Excel and PowerPoint—and show eagerness to learn CRM tools used for sales tracking and customer interactions. Familiarity with these tools adds efficiency.
Willingness to work in Karachi and travel as needed is a must. You may join service or commissioning teams during visits to client locations or project sites—flexibility for varied hours and on-your-feet learning matters.
Being proactive and organized is key. As a trainee, you are expected to assist senior staff, follow up promptly, and take ownership of assigned tasks. Punctuality, reliability, and attention to detail go a long way.
ESL values passion and a long-term mindset. Effective trainees are those who see this as the beginning of their energy sector journey, not just a short-term job.
Although prior exposure to generators, busways, or solar is a plus, it isn’t mandatory. If you have relevant technical experience through internships or project work, it will strengthen your profile, but a strong base of learning-willingness is the priority.
If you align with these traits, you are likely a good match for this role and ready to take your first steps toward a career at ESL in Power Solutions.
Location
These roles are based at ESL’s head office in Karachi, located in the Korangi Industrial Area—ESL House, DP‑01, Sector‑21, Korangi Industrial Area, Karachi, Pakistan (esl.petrolsolutions.com, eslpk.com). You may also receive brief assignments to regional sites or client locations depending on the job requirements.
