Hear from Market Securities builders
Real people, real work, real growth.
“I've shipped more production code in 4 years here than I thought possible. The trust and ownership is unreal — I led the migration to our new matching engine as a Senior, not a Director.”
How we work
Six principles that shape every decision, every PR, every hire.
Ownership
You own outcomes, not tasks. If something is broken, fix it. If something can be 10x better, build it. No one says 'that's not my job'.
Craftsmanship
We sweat the details users will never see — the latency, the error handling, the accessibility tree. Craft is its own reward.
Move Fast
Speed compounds. We ship to prod 50+ times a day. Boring infrastructure lets us move fast without breaking things.
Disagree & Commit
We debate vigorously in the room, then commit fully once decided. No passive-aggressive sabotage, no silent dissent.
Customer Obsessed
Every PR ships a fix or feature that materially helps someone trade better. If it doesn't help a user, we don't build it.
High Bar
We hire people better than half the team. The bar goes up every year. We'd rather have an open role than a mediocre hire.
Different perspectives, better outcomes
We track diversity publicly, hold leaders accountable, and invest in programs that move the numbers.
Where we are today
Employee resource groups
Six ERGs — Women in Trading, Market Securities Pride, Black at Market Securities, Market Securities Latinx, Asians at Market Securities, and Veterans — each with an annual budget, executive sponsor, and direct line to leadership.
Pay equity
We audit pay across gender, race, and tenure annually. The last audit found a 0.3% gap — closed within 30 days. Our compensation philosophy is published openly.
Hiring goals
Every open role has a diverse-slate requirement (at least one underrepresented candidate in final rounds). We partner with /dev/color, AfroTech, and Women Who Code for sourcing.
Grow on the job, on us
