Careers
Build the trust layer
for the AI era.
Ledgible is a small, technical team solving a hard problem that matters. We are building the infrastructure that lets the world know where digital content comes from — and we are looking for people who care about getting it right.
Why Now
A once-in-a-generation infrastructure problem.
The problem is real
AI generates billions of synthetic assets daily, indistinguishable from human-made work. The regulatory clock is running. The enterprise infrastructure to solve this does not yet exist at scale.
The timing is right
EU AI Act Article 50 is live. FTC guidance is in place. Major platforms are adopting C2PA. The window to build the standard is now — before fragmented proprietary solutions lock in.
The work is hard
Cryptography, distributed systems, legal-grade audit infrastructure, and developer tooling — all at once. Every decision we make today will shape how digital content is trusted for decades.
How we work
What we believe about building.
Correctness over speed
We are building infrastructure that organizations will stake legal compliance on. Getting it right matters more than getting it done fast. We do not cut corners on cryptography, audit trails, or data integrity.
Small team, full ownership
Everyone here owns a meaningful surface area of the product. There are no hand-offs for their own sake. If you built it, you understand it — and you are accountable for it in production.
Write it down
We default to written documentation over meetings. Technical decisions get ADRs. Product decisions get design documents. If it is not written down, it did not happen.
Open standards, not lock-in
We build on C2PA, SHA-256, HMAC-SHA256, and open specs — not proprietary formats. Our customers' data should always be portable and independently verifiable.
Transparency as a product
Our public transparency log, open security policy, and verifiable API are not just features — they are our commitment to the same standard of openness we are asking the world to adopt.
Remote-first, async-friendly
We are distributed across time zones. Decisions are made in writing, not in meetings. We optimize for deep focus over synchronous availability.
Open Roles
Where we are hiring.
All roles are based in Austin, TX or fully remote.
Senior Backend Engineer — Cryptography & Ledger
You will own the core signing and verification pipeline — the most critical piece of infrastructure we ship. Every asset record, every HMAC signature, every ledger write goes through systems you design and are responsible for in production. This is not a support role. You will make fundamental architecture decisions on a system that legal and compliance teams at enterprises will stake their regulatory posture on.
What you'll do
- —Design and maintain the HMAC-SHA256 signing pipeline and key lifecycle management
- —Build and scale the append-only provenance ledger (write throughput, consistency guarantees)
- —Own HSM integration — key generation, rotation, revocation, and audit logging
- —Architect the public verification API for sub-50ms p99 response times globally
- —Lead incident response for all signing and ledger infrastructure
Requirements
- —5+ years backend engineering in production systems
- —Deep working knowledge of cryptographic primitives (HMAC, SHA-256, PKI, FIPS standards)
- —Experience with append-only or immutable data stores (event sourcing, log-structured systems)
- —Comfortable with HSM or KMS integration (AWS CloudHSM, Thales, or equivalent)
- —Strong written communication — we make decisions in documents
Nice to have
- —Experience with C2PA or content authenticity standards
- —SOC 2 audit experience or FIPS 140-2 certified environment work
- —Rust or Go; we are open to strong engineers in any language
- —Prior work at a security, compliance, or identity infrastructure company
Developer Experience Engineer
The first thing most customers interact with is not our sales team — it's our docs, our SDK, and our quickstart. You will own all of it. This means writing the Python, Node.js, and Java SDKs, maintaining the API reference, building the sandbox environment, and creating the onboarding experience that takes an engineer from API key to first signed asset in under ten minutes. You will write as much as you code.
What you'll do
- —Build and maintain Python, Node.js, and Java SDKs against the Ledgible REST API
- —Write and maintain the full API reference, guides, and code examples
- —Own the sandbox environment — mocked signing, test keys, simulated verification events
- —Instrument onboarding metrics and reduce time-to-first-signed-asset
- —Talk to developers directly — support forums, Slack, and integration calls with enterprise customers
Requirements
- —Production-grade Python and Node.js — you have shipped libraries others depend on
- —Strong technical writing — you can explain a signing protocol to a junior engineer in three paragraphs
- —Experience designing REST APIs or building against them at depth
- —Empathy for the developer audience — you have been the frustrated user reading bad docs
- —3+ years in a software engineering or developer advocacy role
Nice to have
- —Java SDK experience
- —Familiarity with OpenAPI / Swagger specs
- —Prior work at a developer tools, API, or security company
- —Experience with documentation platforms (Mintlify, ReadMe, Docusaurus)
- —Understanding of HMAC signing, JWT, or OAuth flows
Enterprise Account Executive
You will build our enterprise revenue from the ground up. Our buyers are VP Legal, General Counsel, CISO, and CTO — people who understand regulatory risk and care deeply about provenance infrastructure. You will run the full sales cycle: identify and qualify prospects in media, AI, and advertising, run technical discovery with engineering teams, navigate legal and procurement, and close. This is an early role — you will help define what enterprise sales looks like at Ledgible.
What you'll do
- —Own a quota and manage the full enterprise sales cycle from outbound to close
- —Build pipeline in media publishing, enterprise AI, and agency/advertising verticals
- —Run technical discovery calls alongside engineering to scope integrations
- —Navigate enterprise procurement, security review, and legal negotiations
- —Feed market intelligence back to product — you are the voice of the buyer
Requirements
- —5+ years closing enterprise deals ($100K+ ACV)
- —Experience selling into Legal, Compliance, or Security buyers
- —Ability to hold a credible technical conversation with engineering teams
- —Track record of building pipeline from scratch — not inheriting warm territory
- —Comfortable in early-stage environments where process is still being built
Nice to have
- —Prior experience selling security, compliance, or data infrastructure
- —Existing network in media publishing or enterprise AI
- —Understanding of EU AI Act or content authenticity regulatory landscape
- —Experience with usage-based or API-first pricing models
Security & Compliance Engineer
Security is the product at Ledgible — not a support function. You will own our SOC 2 Type II audit readiness, operate the HSM infrastructure, and be the primary point of contact when enterprise security teams conduct reviews before signing contracts. You will also own our public transparency log, incident response procedures, and the security controls that sit between our signing infrastructure and every customer who depends on it.
What you'll do
- —Own SOC 2 Type II audit readiness — controls, evidence collection, auditor coordination
- —Operate HSM infrastructure including key generation, rotation schedules, and revocation procedures
- —Lead enterprise security reviews — respond to customer security questionnaires and on-site assessments
- —Maintain the public transparency log and internal security event audit trail
- —Define and test incident response procedures; be on-call for security events
Requirements
- —Direct experience with SOC 2 Type II audit preparation and remediation
- —Working knowledge of FIPS 140-2 and HSM operations (AWS CloudHSM, Thales nShield, or equivalent)
- —Experience writing and operating security controls in a cloud environment (AWS preferred)
- —Familiarity with cryptographic key management lifecycle
- —4+ years in a security engineering or security operations role
Nice to have
- —CISSP, CISM, or equivalent certification
- —Experience with EU AI Act or regulatory compliance frameworks beyond SOC 2
- —Background in fintech, legaltech, or other regulated industry security
- —Familiarity with C2PA or content authenticity standards
- —Prior work at a company that sells into enterprise legal or compliance buyers
Product Designer
You will be the first dedicated designer at Ledgible. The product spans a developer-facing API, a compliance dashboard used by legal teams, and a public verification experience used by anyone. Getting all three right requires someone who can move fluently between developer tooling aesthetics and the trust and restraint required by institutional buyers. You will own design end-to-end — research, flows, components, and production handoff.
What you'll do
- —Own the design of the dashboard — asset management, analytics, API key management, and compliance exports
- —Design the public verification flow: the experience for journalists, regulators, and consumers checking asset authenticity
- —Build and maintain a component library aligned to the Ledgible brand system
- —Run lightweight user research with developers and legal/compliance buyers
- —Work directly with engineers — no PM layer, no design-by-committee
Requirements
- —Strong Figma skills — components, auto-layout, prototyping, and dev handoff
- —Portfolio showing complex SaaS or developer tool product design
- —Ability to design at multiple fidelity levels — rough flow to production-ready spec
- —3+ years in product design, preferably at a B2B SaaS company
- —Comfort working without a dedicated PM — you will need to drive scope decisions
Nice to have
- —Experience designing for compliance, legal, or security products
- —Familiarity with design systems at a brand standard level (tokens, documentation)
- —Basic frontend knowledge — you can read JSX and spot implementation drift
- —Experience designing data-dense dashboards (analytics, audit logs, tables)
- —Prior work at an early-stage startup as the sole or first designer
