All qualified individuals will receive consideration for employment opportunities without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or status as a protected veteran.

Why Crossflow?

Crossflow Technologies is proud to offer such wonderful benefits and perks to our employees; however, we feel the biggest perk is our company culture. We harbor a culture that extends down to the individual level by hiring people who understand and embrace our company values. Values like fervently protecting work-life balance and celebrating the achievements of others. To help guide and shape this environment, we strive to solicit feedback as frequently as possible through direct conversations and anonymous input. We take great pride in the fact that we have been contenders for the Best Places to Work award for the past few years - particularly when paired with having made the Inc. 5000 list for growth. To us, this demonstrates our ability to effectively scale our culture showing that Crossflow has been and continues to be, a place that people want to be.

Benefit-Eligible Employee Perks:

Health coverage choices (including an HSA) ranging from $0.00 to $403.14;
Dental coverage ranges from $8.23 to $31.65; and
Vision coverage ranges from $8.28 to $21.80

CROSSFLOW KUDOS SPOT BONUS PROGRAM

We created a unique performance bonus program called Crossflow Kudos. Throughout the year, employees are nominated by other employees, company leads, and even individuals outside of Crossflow to receive additional compensation and personal recognition for their positive work. There are six broad categories in which employees can earn Kudos awards.

401(k) RETIREMENT PLAN & COMPANY MATCHING

Crossflow uses Principal as our 401(k) plan sponsor. Employees can choose payroll deduction and fund investing options. Payroll deductions will begin the month following your enrollment. Crossflow matches 100% of the first 3% of compensation, plus 50% of the next 2% of compensation.

Employee Stock Ownership Plan (ESOP)

Crossflow Technologies offers benefit-eligible employees participation in an Employee Stock Ownership Plan (ESOP). Through the ESOP, eligible employees may receive an ownership interest in the company, creating an opportunity to share in Crossflow's long-term success while building retirement value alongside our other employee benefits.

HIGHER EDUCATION ASSISTANCE PROGRAM

Crossflow offers education assistance to benefit-eligible employees for degree programs at their director's discretion. Crossflow feels that a well-rounded education, even outside of an employee's current role, can enhance an employee's skillset and increase the company's value.

GENEROUS PTO ACCRUAL & FLEXIBLE LEAVE POLICY

Crossflow currently grants 11 federally observed paid holidays. In addition to these holidays, Crossflow offers a minimum of 2 weeks of paid time off (PTO) to all full-time employees. Employees may utilize PTO for any reason (sickness, vacation, personal day, etc.) and can carry over a maximum of 120 hours from year to year. Many employees are authorized to work additional hours within a normal, forty-hour pay period. This approval is included in the employee's offer letter for employment. These extra hours may be banked for compensatory (comp) time off.

PAID PARENTAL & BEREAVEMENT LEAVE

To help our employees be present with family during major life events, Crossflow provides additional PTO. We offer varying types of paid Parental Leave to aid birthing, non-birthing, and adoptive parents transition into parenthood. Crossflow also recognizes the importance of supporting employees who endure a death in their family by providing up to 5 days of paid Bereavement Leave a year.

PROFESSIONAL DEVELOPMENT FUNDING

We support employees who seek out personal or professional growth opportunities through countless of enabling programs to further equip themselves. Professional Development includes, but is not limited to, training courses, certificate programs, memberships to industry groups, and materials.

EMPLOYEE DRIVEN COMMUNITY ENGAGEMENT

We create as many opportunities as possible for employees to meet and build community. We offer monthly team bonding activities, allowing team members to assemble on a different level than at work. In addition to these gatherings, in 2021 we established Crossflow Cares, an employee-owned and operated charitable organization focused on awarding grants and providing volunteers to local non-profits. Furthermore, Crossflow Technologies is committed to serving the public by investing a large portion of our net income in the greater Huntsville/Madison County area.

MENTORSHIP PROGRAM & MORALE LUNCHES

The most successful people in the world always have a terrific team behind them, and Crossflow chooses to be the team behind the people, cheering our employees on to meaningful successes. Our Mentorship Program involves strategically pairing a protégé with a mentor who understands an employee's career aspirations and provides coaching towards that goal. A less structured version of this is our Morale Lunch program. We committed a portion of our budget to support our leads to meet with their team members over lunch and facilitate quality catch up sessions. The morale lunches have become a great tool for maintaining open communication and gaining insightful feedback.
