Job description

BUILT ON FLAVOR. FUELED BY PEOPLE.
What's it like to work at Kinder's? Well, there's a lot of snacking and geeking out over what we all cooked over the weekend. Beyond that, there's also plenty of hard work. Because we don't just like flavor, we're obsessed with it.
With over 100 products sold nationwide, we're now a top-five brand in multiple flavor categories at Costco, Walmart, Whole Foods, and more. We're not your typical CPG company. Privately held and founder-led, we like to think of ourselves as a pirate ship in a sea of cruise ships. Our crew is adventurous and fearless. We chart our own course and chase big ideas to make food unforgettable.
As we expand globally and approach $1 billion in revenue, we need more smart-and-scrappy, flavor-obsessed people to come aboard. If you're looking for a place where you can see the real impact of your work... this is it! Every day, you'll be part of a journey to add flavor to millions of meals and lives.
How You'll Have Impact at Kinder's:
You will play a key role supporting Kinder's by designing, implementing, optimizing, and continuously improving manufacturing processes
What You'll Be Doing:
We are looking for a highly detail-oriented Sr. Process Engineer to assist in development, control, and documentation of food manufacturing process to assure we produce top quality food with consistency
  • Develop and optimize production processes in partnership with co-manufacturers
  • Identify inconsistencies and assist in continuous improvement initiatives
  • Develop and maintain process documentation and work instructions
  • Travel to co-manufacturing sites to support trial and first production activities
  • Support onboarding of new co-manufacturers including process transfer and validation
  • Collect, analyze, and interpret production data to drive data-based decisions
What You Bring to the Table:
Skills and Experience:
  • Bachelor's degree in Engineering (Mechanical, Chemical, Industrial, or related field)
  • Strong problem solving and data analysis skills, outside the box thinking
  • Willingness and ability to travel (50%)
  • 5-7 years experience in process engineering or food manufacturing
Personal Characteristics:
  • An ambitious individual that wants to grow their skillset at one of the premier, growing food companies.
  • Self-Starter that requires minimal oversight with an ability to problem solve, manage multiple priorities simultaneously.
  • Very strong organizational skills and an extremely disciplined approach to database and documentation management
  • Excellent attention to detail and ability to manage multiple projects and tasks
  • Effective communication and teamwork skills are critical.
  • Accustomed to changing priorities and a high tempo, dynamic environment.
  • Strong interpersonal skills and a great attitude to support a high growth company

Location & Pay Transparency
This position will be based onsite in Walnut Creek, CA. Additionally, it will involve 50% travel; predominantly in the U.S. The expected starting salary range for this role is $115,000-$130,000 per year. We may ultimately pay more or less than the posted range based on the location of the role. The amount a particular employee will earn within the salary range will be based on factors such as relevant education, qualifications, performance, and business needs.
SEASONED FOR SUCCESS:
  • No two days here are the same.
  • We try to be good team members and good communicators, but we don't live by hierarchy and structure - everyone is a difference maker here.
  • We make a lot of decisions in the face of incomplete information - our team embraces ambiguity and tries to make good decisions fast rather than great decisions slow.
  • We believe our job is to take smart risk, not to eliminate risk.
  • We believe in growing our skills and becoming a better company with more managerial expertise, but we are an entrepreneurial company at heart.
  • We aren't trying to be average - we want to do exceptional things, and we are willing to work hard to achieve them.
BENEFITS THAT BRING MORE TO THE TABLE:
We offer a range of total rewards that may include paid time off, 401k, bonus / incentive eligibility, equity grants, competitive health benefits, and other family-friendly benefits, including parental leave. Kinder's benefits vary based on eligibility and can be reviewed in more detail during the interview process.
OUR RECIPE FOR BALANCE:
We believe great culture starts with people. We're a people-first company built on connection, collaboration, and balance. Most of our work happens in the office to spark creativity and community, but we also offer flexibility so team members have the autonomy to work outside the office when needed to support their work-life balance and personal commitments.
WHERE EVERY INGREDIENT MATTERS:
Kinder's is an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, ancestry, national origin, gender, citizenship, marital status, religion, age, disability, gender identity, results of genetic testing, veteran status, as well as any other legally-protected characteristic.
