About Us
Salient builds AI agents for regulated financial services. Our agents automate loan servicing, compliance, collections, recovery, insurance claims, and disputes for banks, captives, and specialty lenders.
We are:
Backed by a16z and Y Combinator, with $75M raised in Series A funding
Cash flow positive and profitable, with mid eight figure ARR achieved in under two years
Already serving more than 20% of the auto lending industry
Processing millions of real customer calls and transactions every day
Fully deployed in production with major financial institutions
Actively expanding into new financial services segments
Building together in person in San Francisco
We are deeply integrated with our customers, own the full technology stack, and move quickly to bring modern AI into regulated industries where precision, reliability, and performance matter.
About the Role
We're hiring a Telephony Infrastructure Engineer to own the voice platform behind Salient's AI agents: the SIP edge, Asterisk, the voice audio and dialing layers, and the call servers that connect borrowers to our agents. You will work directly with our AI agent engineers, telephony specialist, customer success, and carriers.
This is a hands-on ownership role. You will finish work in flight, make the platform reliable and safe to change, and prove it can handle the next order of magnitude of call volume. You will also design and implement customer telephony integrations and make them increasingly self-serve.
What You'll Own
- Finishing the Asterisk migration: cutting over remaining customers, trunks, and call flows with no regression, then retiring the legacy path.
- Reliability of the voice audio and dialing layers: SLOs, monitoring, incident response, and eliminating recurring failure modes.
- Zero-downtime call-server deployments: draining, graceful shutdown, safe rollout, and rollback without dropping live calls.
- Building tools to manage Kamailio and Asterisk reconfiguration without server restarts inside Kubernetes
- Backpressure, load shedding, and self-recovery when carriers, media, or AI dependencies degrade.
- Load testing and capacity planning that validates thousands of concurrent calls and CPS at the SIP edge.
- Voice observability: call-quality and platform-health metrics, alerting, runbooks, and postmortems.
- Security of the voice edge against scanning, toll fraud, and abuse.
- Customer telephony integrations: custom SIP trunks (e.g., Genesys, Bandwidth), call transfers, SIP header passing, and API prototypes with new contact-center platforms.
- Self-serve setup: productized trunk configurations, validation tooling, and docs that shorten time to go live.
What We're Looking For
- You've run production voice infrastructure at meaningful scale and have been on call for it.
- You know SIP, SDP, and RTP deeply and debug from traces and pcaps.
- You can debug EC2/K8s networking issues that result in deadair—and develop monitoring and testing plans to minimize deadair.
- You understand real-time media, WebRTC, and latency budgets.
- You design for backpressure, graceful degradation, and safe deploys of stateful services.
- You've built load tests that found real bottlenecks before customers did.
- You write clear design docs, runbooks, and postmortems.
- You've integrated SIP trunks with customer contact centers and carriers, including transfers and header passing.
Nice to Have
- Experience with Kamailio, Asterisk, OpenSIPS, FreeSWITCH, or rtpengine.
- Experience developing regional failover for SIP
- Experience with latency-aware multi-homing
- Experience with contact-center, dialer, CpaaS, or carrier infrastructure.
- Experience with AI voice agents, speech pipelines, or regulated industries such as lending.
- Experience with contact-center platforms such as Genesys, Five9, NICE, or Amazon Connect.
Why This Role
Every Salient product depends on a phone call working. You will own the platform that carries those calls and make it reliable, easy to change, and ready for the volume our customers are about to send it.
At Salient, we’re building at the edge of AI - fast, focused, and with real ownership. Sprints and major launches move quickly, and we look for people who are energized by that pace. Our team typically works around 60 hours per week, beginning at 8:00 AM, with four days spent collaborating in person at our San Francisco office.
We also offer a benefits package designed to support our full-time employees: medical, dental, and vision coverage, a generous 401(k), and catered lunches.
By applying, you acknowledge that your personal information will be processed in accordance with our Privacy Policy.
Compensation Range: $200K - $300K

Infrastructure Engineer Jobs in California: Frequently Asked Questions
How do you become an infrastructure engineer in California?
Most infrastructure engineer roles in California require a bachelor's degree in computer science, information systems, civil engineering, or a related field. California does not issue a state-specific license for IT infrastructure engineers, but civil infrastructure roles may require a Professional Engineer license through the California Board for Professional Engineers, Land Surveyors, and Geologists. Employers across the state consistently prioritize cloud certifications, networking credentials, and demonstrated hands-on project experience alongside formal education.
Which companies hire infrastructure engineers in California?
Employers hiring infrastructure engineers in California right now include Google, Apple, and Tesla, based on current listings on Migrate Mate as of September 2026. California's concentration of large tech firms, defense contractors, and integrated health systems means infrastructure engineering demand is distributed across multiple industries rather than a single sector.
Which California cities have the most infrastructure engineer jobs?
San Francisco, Sunnyvale, and San Jose have the most infrastructure engineer openings in California right now. The San Francisco Bay Area leads due to its density of cloud and enterprise technology companies, while Los Angeles draws demand from entertainment technology, aerospace, and large healthcare networks, and San Diego's concentration of defense contractors and biotech firms sustains steady openings there.
Are there remote infrastructure engineer jobs in California?
Yes, and more than most technical fields. About 46% of infrastructure engineer openings tied to California are remote or hybrid as of September 2026, reflecting how much of the role involves managing cloud platforms, virtualized environments, and software-defined networks that require no physical presence. On-site requirements are most common for roles involving hardware installation, data center operations, or physical network maintenance.
How can I get hired as an infrastructure engineer in California with little or no experience?
The most realistic entry path is securing a helpdesk, systems administrator, or IT associate role at a large California employer, then building toward infrastructure work from there. Companies like Kaiser Permanente, the University of California system, and major Bay Area tech firms run associate IT programs and rotational technical training tracks that accept candidates without direct infrastructure experience. Earning a cloud certification such as AWS Cloud Practitioner or a networking credential like CompTIA Network+ before applying gives candidates a measurable edge in California's competitive entry-level market.
Where can I find and apply to infrastructure engineer jobs in California?
You can find and apply to infrastructure engineer jobs in California on Migrate Mate, which lists current California openings across cloud, network, civil, and data center infrastructure roles. Find the roles that fit your experience level and location and apply directly through the listings.
