Beyond compensation, ESI offers a variety of perks to enhance your work-life integration and foster team spirit. From happy hours and company picnics to sponsored events like Capitals/Nationals games, live shows, and holiday dinners, we create opportunities to connect, celebrate, and build camaraderie as a team.
ESI values continuing education and supports employees in furthering their career goals. That’s why you can qualify for up to $4,000 in tax-free professional development reimbursement each year. Whether you’re working on a related Master’s degree or keeping up with the latest technology – or both – if it’s related to your work at ESI, we will invest in your career.
Choosing health insurance is an important decision for you and your family. ESI offers four different medical plans, including one that is paired with an HSA. We also have dental and vision plans, so you can tailor coverage to meet your specific needs.
CareFirst medical insurance options include both regional HMO and national PPO plans with multiple levels to fit the needs of you and your eligible family members. Each plan includes:
CareFirst Dental insurance is a national PPO plan that provides your family with routine preventative care and assistance with the more expensive aspects of dental health.
CareFirst Vision coverage makes regular exams and the purchase of glasses and contacts simple and affordable.
For those choosing the High Deductible Healthcare Plan, a HSA is available to set aside pre-tax dollars for your future healthcare needs. An HSA is like a retirement plan for your healthcare needs.
Health Care FSAs allow you to set aside pre-tax dollars to pay for qualified medical, dental, and vision expenses – those that are not covered by your health plan or anywhere else.
This FSA type allows you to set aside pre-tax dollars to pay for eligible dependent care expenses like child or adult daycare programs. You’ll save money while providing care for your family so that you can continue to work.
Through UNUM, all employees can use a free, confidential Employee Assistance Program to help with many of life’s challenges. The EAP includes resources to get you started in meeting your mental wellness needs, relationship challenges, life events, financial counseling, and more.
Any unplanned incident that affects your ability to earn income is stressful. Our income insurance helps reduce that stress and gives you support when you need it most.
Group Term Basic Life Insurance is available in the amount of 100% of your annual salary, up to $250K. ESI pays 100% of all premium costs. ESI also provides the option of adding on voluntary (or supplemental) life insurance up to $500K for yourself. You can add coverage for your spouse and children as well.
Short-term Disability insurance covers 60% of your monthly income, up to a maximum of $8,000/month. ESI pays 100% of all premium costs.
Long-term Disability insurance covers 60% of your salary, to a maximum of $8,000/month. ESI pays 100% of all premium costs.
New parents need time to bond with children, and we support taking care of your family. That's why employees receive 10 paid days off following the birth, adoption, or foster placement of a child in their home.
Vacation Leave starts accruing on your first day with ESI, and we regularly encourage you to use some or all your annual vacation leave to rest, relax, and pursue special interests. Generous vacation carry-over is automatically applied annually.
ESI follows the federal government (OPM) standard holiday schedule, granting employees the following 11 paid holidays:
We all need time to recuperate when not feeling well. That’s why ESI provides 40 hours of annual sick leave (pro-rated for new employees). You’ll start with 40 hours of sick leave at the beginning of each year and can carry over up to 200 hours at the end of each year.
ESI employees receive up to 5 days (40 hours) of paid time off for jury duty.
PARENTAL LEAVE (for Mothers and Fathers)
ESI offers paid parental leave for the first 10 missed workdays following the birth, adoption, or placement of a foster child.
ESI offers from 1 to 3 days for bereavement leave in the event of the death of an immediate family member.
We encourage all our employees to plan for their financial future. By offering both pre-tax traditional 401(k) accounts and post-tax Roth 401(k) Safe Harbor accounts, and contributing a match of up to 4% every pay period, ESI’s Retirement Savings plan can help you meet your financial goals.
