Life at Ontra

Culture Impact Belonging

Being an Ontranaut

At Ontra, brilliance without empathy isn’t our style. We challenge each other’s thinking, hold ourselves to a high bar, and show up for the people around us with the same seriousness we bring to the work. Our culture is built on genuine relationships and shared ideas.

How we work

Working at Ontra means building together, not competing. We communicate openly, document well, and make decisions with care. We’re an AI-native organization, and we use that advantage deliberately: to move faster, think more clearly, and keep our focus on the complex, high-judgment work that defines what we do.

Remote-first by design

We’ve built something real across distance. Our remote-first culture is supported by office hubs in London and New York, team offsites, and the kind of day-to-day collaboration that keeps people invested in each other. Wherever you’re based, you’ll find your people here.

Ownership from day one

At Ontra, ownership isn’t something you work toward. It’s what we expect from the start. You’ll be trusted with real responsibility early, with clear accountability for outcomes. We ask bold questions, address root causes, and make sure problems stay solved. Every person’s contribution counts.

Doing work that counts

The problems we solve are sophisticated because our customers are.

Working hard means working smart

with discipline, autonomy, and the kind of curiosity that doesn’t stop at good enough. The pace is fast by design, not by accident, and every challenge is a chance to build sharper judgment and deeper expertise.

Development at every level

Growth at Ontra isn’t just a program. It’s a byproduct of the work itself. You’ll be stretched by the work and supported by people invested in your success. Your career here is yours to own, and we’ll make sure you always know where you stand and what’s possible.

Our belonging commitment

At Ontra, belonging is a shared responsibility. We believe a team that brings different perspectives, identities, and experiences to hard problems builds better solutions, and we’re intentional about creating the conditions for that to be true.

Inclusive from the start

Our commitment to inclusion starts with how we hire. We build processes that are clear, consistent, and structured so that every candidate is evaluated fairly and seen for the strengths they bring.

Employee Resource Groups (ERGs)

Our five employee-led ERGs, All Kinds of Asians, Nosontros, OntRainbow, Ontra Womxn’s Network, and Parents at Ontra, connect Ontranauts. These communities drive mentorship, professional growth, and a genuine sense of belonging. Open to allies, they’re one of the ways we make sure everyone at Ontra has people in their corner.

Perks and Benefits

We ask a lot of Ontranauts. Our total rewards are how we make sure we're taking care of you in return.

Health & family

Comprehensive medical, dental, and vision coverage and wellness resources for your overall well-being. Family-focused benefits, including parental leave, are designed to support your whole life, not just the hours you're working.

Financial wellness

Our philosophy is simple

when you help build Ontra’s future, you share in it. Competitive compensation, equity, and retirement benefits are designed to support long-term financial security and give you a stake in what you’re building.

Time off

Time away from work is part of doing great work. We offer generous paid time off, company holidays, and volunteer time reporting because we know that showing up at your best means having real space to step away from the work too.

AI & growth

You'll have access to leading AI-powered tools and technologies, paired with real skill-building opportunities and ongoing feedback. Clear career paths and regular performance cycles mean you always know where you stand and what's next.

Remote-first

Flexibility and connection are part of the same experience at Ontra. We're remote-first by design, giving you the autonomy to work where you do your best, with office hubs in London and New York City and intentional opportunities to come together.

Lifestyle wallet

Our perks are built to fit your life, not the other way around. We provide phone and internet stipends, and Pick Your Perk funds can be used for everything from wellness and pet care to student loans and home office needs.

Our Values

• Act Like Owners We focus on the things that really matter to the whole company. We drive great outcomes by being practical, resourceful, accountable and long-term oriented.
• Obsess Over Our Customers We make our customers successful. We understand their problems, concerns and opportunities. We deliver on the jobs to be done and build long-term relationships.
• Play to Win We deliver exceptional performance, individually and as a team. We do what it takes to win, every day.
• Do the Work We dig in, taking responsibility and going to ground on the issues. We solve problems to stay solved.
• Communicate Openly We are transparent with our stakeholders on issues and priorities. We communicate candidly and empathetically, with the goal of serving each other.
• Are Always Improving We innovate, both boldly and incrementally, on the way we work and the products we deliver. We continually invest in ourselves and our teams.
