Summary Generated by Built In

Avante is the enterprise AI platform for benefits teams. Benefits is one of the most complex, high-stakes functions in any company, and Avante’s purpose-built agents take on end-to-end benefits work, from checking vendor contracts against claims to preparing leadership reports to helping employees use and understand their benefits. Samsung Semiconductor, Real Chemistry, Zscaler and News Corp use Avante today to keep costs in check, support employees across the globe, and get more from their benefits investment.

The Role

As a Software Engineer at Avante, you will design and build production systems across our TypeScript stack, increasingly directing AI agents to handle implementation while you own the architecture, correctness, and quality of what ships. This is a hands-on engineering role: you will solve real technical problems, ship features, and make pragmatic decisions that balance speed with maintainability. Your judgment about when to build directly and when to guide an agent will shape work that reaches Avante's enterprise customers directly.

What You'll Do

AI-Native Engineering

  • Build and extend the AI infrastructure behind Carly and Ava, including prompt engineering, context management, agent orchestration, and reliable AI system integration
  • Use AI coding tools (Claude Code, Cursor, or similar) as a core part of how you ship, with sharp judgment about where they accelerate work and where they fall short
  • Increasingly direct AI agents to handle implementation, staying responsible for the architecture, correctness, and quality of what ships
  • Help decide when and how AI agents get used as part of technical decision-making

Product & Customer Impact

  • Collaborate closely with product, design, and engineering peers to deliver solutions that drive real business value, with a clear point of view on what's actually right for the customer
  • Participate in design discussions and code reviews

Ownership & Execution

  • Own outcomes across our TypeScript backend services and APIs, writing production code yourself
  • Design, build, and maintain scalable services within our TypeScript monorepo, as we move toward a "touchless PR" model where agents handle more of the mechanical implementation and engineers focus on the judgment calls
  • Model data, design schemas, and optimize queries in PostgreSQL
  • Integrate with external systems including HRIS platforms, ticketing systems, and third-party APIs
  • Build for production with attention to observability, monitoring, and testability from day one
What We're Looking For
  • 3+ years of professional software engineering experience, primarily in backend development
  • Strong proficiency in TypeScript or willingness to ramp quickly if coming from similar languages (Java, C#, Python)
  • Solid experience with relational databases: schema design, query writing, and performance basics
  • Familiarity with API design patterns and building services that other systems depend on
  • Active engagement with AI engineering: hands-on experience with LLM APIs, agent workflows, or AI-assisted development, plus a real point of view on how AI is changing what a strong engineer owns and how they work. Self-directed exploration outside of work counts as much as production usage
  • Demonstrated product and customer judgment: a track record of decisions that weigh what's technically correct against what's actually right for the end user
  • Startup or high-ownership experience: comfort operating without a large team or established process behind you, and a bias toward shipping and iterating over waiting for a long spec
  • Ability to work effectively in ambiguity and balance speed with maintainability
  • Strong communication skills and genuine interest in understanding the problems you're solving
What to Expect from Us

Interview Process:

  • Initial screen with our recruiters
  • Video Interview with our Engineering Manager
  • Technical interview focused on real-world problem solving (no whiteboard algorithms)
  • On-site interview loop:
    • Team behavioral interview (60 min)
    • Session with our Engineering Manager (60 min)
    • Final conversation with our CTO (30 min)
The base salary for this role is $130,000–$170,000. Where you land in that range depends on your experience, your skills, and how well your background fits what the role needs.

We also offer:

  • Equity: Stock options, so you share in what we’re building
  • Health coverage: Medical, dental, and vision, with employee premiums covered by Avante
  • Unlimited PTO: Take the time you need to rest and recharge, plus paid company holidays
  • Retirement: 401(k)
  • Commuter benefit: $150/month toward however you prefer to get to work

Avante is an Equal Opportunity Employer. We’re building a diverse, inclusive team and welcome candidates of all backgrounds.

How We Work

Our four values aren't aspirational. They translate into concrete operating tenets that shape how we make decisions every day.

Beat Yesterday. We re-evaluate our own toolkit every quarter, because the workflows that made you effective three months ago may already be outdated. We act on 70% of the information rather than waiting for certainty. We timebox, execute, and iterate, getting work in front of real people quickly instead of polishing in isolation. And we own our output regardless of how we produced it. AI can get you 80% of the way there. Everything that goes out with your name on it is your responsibility to review, refine, and stand behind.

Embrace Type 2 Fun. We take on hard problems and find meaning in the work, even when it's uncomfortable. We assume good intent and follow up directly rather than venting in side channels. We celebrate wins loudly and specifically, naming the actual behavior so the whole team learns what great looks like. We are on by default, because we owe it to each other and to our customers to be available beyond what a regular corporate job would demand. And we do unscalable things today that build scalable advantages tomorrow: every hand-built account play and late-night proposal turnaround earns us the right to scale later.

Stay Hungry, Stay Curious. We expect everyone to be the expert on AI in their function before anyone asks them to be. The landscape changes weekly. When you learn something, teach it. Learn enough about adjacent functions to ask good questions. Ask the question you think is too basic, because in complex domains like benefits, the cost of a wrong assumption can be a lost account. And remember: curiosity without urgency is a hobby. Learning has to translate into action on a timeline that matches the opportunity.

Act Like an Owner. We say the uncomfortable thing early, raising missed commitments or quality gaps directly with the person within 48 hours. We surface problems when they're small, not the week they become a crisis. Customer-facing work gets priority, always. And we close the loop every time, because over-communication is a feature at our stage, not a bug.

Skills Required

  • 3+ years of professional software engineering experience, primarily in backend development
  • Strong proficiency in TypeScript or willingness to ramp quickly from similar languages such as Java, C#, or Python
  • Experience with relational databases, including schema design, query writing, and performance fundamentals
  • Familiarity with API design patterns and building services used by other systems
  • Hands-on experience with LLM APIs, agent workflows, or AI-assisted development, including a perspective on AI engineering
  • Demonstrated product and customer judgment
  • Startup or high-ownership experience with a bias toward shipping and iteration
  • Ability to work effectively in ambiguity while balancing speed and maintainability
  • Strong communication skills and genuine interest in understanding problems being solved

Avante Compensation & Benefits Highlights

  • Fair & Transparent Compensation — Compensation transparency is highlighted through clearly published salary bands and structured commission tiers, which helps set expectations early for candidates.
  • Equity Value & Accessibility — Equity or stock options are commonly paired with base pay, aligning longer-term incentives for early-stage hires.
  • Retirement Support — 401(k) plans are identified among the core benefits, indicating baseline retirement offerings consistent with tech-sector norms.

What We Do

Avante is the enterprise AI platform for benefits teams. We help companies run and improve their benefits with AI. Benefits is one of the biggest investments a company makes, and costs keep rising. Employers expect a median 9% increase in health care costs for 2026 (Business Group on Health, 2026). Yet 85% of employees say they're confused about their benefits (Businessolver, 2026). Carly answers employees' benefits questions 24/7 in 80+ languages, in Slack, Microsoft Teams, email, the web and ServiceNow. Every answer comes from the employer's own plan documents, with sources. Ava Workbench gives benefits teams reports and analyses of claims, contracts and vendor performance in minutes, not weeks. Ongoing work, like recurring vendor reviews and employee trend reports, goes to Ava Agents (beta). Avante works alongside a company's benefits administration system, broker and enterprise AI rather than replacing them. We work with self-insured employers with 1,000+ employees, including Samsung Semiconductor, Real Chemistry, Zscaler and News Corp. Partners help us reach smaller employers. Samsung Semiconductor used Avante to build targeted communications and raised use of its mental health benefit 66%. Founded in 2023, Avante is based in Seattle with an office in New York.

Our mission is to make benefits simple and clear for people and organizations. At Avante, you'll build AI for one of the most complex functions in any company, owning real problems early with teammates in Seattle and New York. Our values: Beat Yesterday. Embrace Type 2 Fun. Stay Hungry, Stay Curious. Act Like an Owner.
