What they're building

Exchange-side engineering: core exchange, clearinghouse and trading APIs moderate signal

Today: Software Engineer, Trading Platform posting describes 'a next-generation financial ecosystem (think NYSE or CME from scratch)' spanning core exchange, clearinghouse and broker connectivity

Roles: Software Engineer, Trading Platform · Infrastructure Engineer · Software Engineer, Product · Site Reliability Engineer

Requirements mention: core exchange · clearinghouse · API infrastructure · Order matching · FIX API · broker connectivity

Inference: exchange engineering hiring is centred on the core exchange, clearinghouse and trading/broker APIs. Three roles name these systems and the SRE posting describes the same build. Two of these postings date to 2021 and 2022, so they may be standing requisitions.

Automated trading at the affiliated entity Kalshi Trading LLC moderate signal

Today: Trading Systems Engineer posting describes Kalshi Trading as 'an affiliated trading entity that operates across all different categories on Kalshi'

Roles: Trading Systems Engineer (Kalshi Trading LLC) · Quantitative Developer (Kalshi Trading LLC)

Requirements mention: automated liquidity provision · position management · Kalshi API · low latency programming · stream processing · generative AI

Inference: the affiliate is staffing automated trading and liquidity provision on Kalshi's markets. Its Trading Systems Engineer role, opened 2026-09-03, is the most recent posting in the set.

TV, streaming and social acquisition in the Growth department moderate signal

Today: Performance Marketing posting says 'Kalshi's growth team is scaling its exchange'

Roles: Linear/Streaming Lead · Marketing Activations & Operations · Growth Marketing Manager · Partnerships - Social Media · Video Editor · Performance Marketing

Requirements mention: linear TV · CTV/OTT · paid acquisition · launching high-impact campaigns

Inference: with six roles, Growth is the largest group outside Engineering, and its open roles point to national TV, streaming and social channels as a hiring focus.

Compliance, operational risk and legal staffing around the regulated exchange moderate signal

Today: Legal (Market Contracts) posting says Kalshi 'has launched the first regulated financial exchange that allows people to trade on the anticipated outcome of events'

Roles: Operations Risk Analyst · Operations Risk Lead · Paralegal · Legal (Market Contracts)

Requirements mention: clearing processes · CFTC regulations · drafting and negotiating contracts · DCM/DCO filings

Inference: four Compliance roles covering clearing risk, CFTC filings and market contracts suggest regulatory operations are being staffed alongside the exchange.

Payments and consumer product roles weak signal

Today: Payments Lead posting says Kalshi 'is building prediction markets, a new category that allows people to trade on the outcome of any events'

Roles: Payments Lead · Product Designer · Product Manager

Requirements mention: payments roadmap · PSP integrations · consumer fintech

Not inferred: three roles across Product, weak signal.

Finance roles tied to reporting and clearing weak signal

Today: Finance Operations posting lists 'Kalshi Klear' and 'Clearing Org' as requirements

Roles: Technical Accountant · Strategic Finance Analyst · Finance Operations

Requirements mention: U.S. GAAP · investor reporting · Kalshi Klear

Not inferred: three roles, weak signal.

How to use this

If you're applying: Apply to Engineering roles only if your stack matches the listed requirements, such as Golang, Rust, Kafka or Postgres. No roles opened in the last 30 days and several postings date to 2021–2023, so check each posting's date and ask whether it is actively hiring. The two Kalshi Trading LLC roles are with an affiliated trading entity, not the exchange itself.

If you're selling or recruiting: Call about the four exchange engineering roles (core exchange, clearinghouse, trading APIs), the two Kalshi Trading LLC trading roles, or the six Growth roles on TV, streaming and social. The velocity flag is freeze and several postings are years old, so confirm which openings are still being filled.
