Trellis is hiring a Senior Backend Engineer for Provider Integrations, and the competition will be serious. This is a high-impact role at a profitable Series A startup backed by General Catalyst and Amex Ventures, offering a salary range of $159,000 to $210,000. Getting your resume right is the first step toward earning an interview.
Understand What Trellis Actually Needs
Trellis connects its insurance platform, Savvy, to over 150 insurance carrier and partner APIs. The Provider Integrations team owns that infrastructure. Your resume needs to speak directly to that mission.
This is not a generic backend role. Trellis wants someone who can architect reliable systems at scale, lead technical direction on complex projects, and mentor teammates. Leadership and engineering depth both matter here.
Read the job description carefully. The role touches API integrations, traffic routing and ranking, provider attribution, and full software development lifecycle ownership. Each of those areas is a signal for what to include on your resume.
What to Highlight on Your Resume
API Integration Experience
This is the core of the role. If you have built or maintained integrations with third-party APIs at scale, that experience belongs front and center. Quantify your work wherever possible.
- Number of APIs or external systems you integrated
- Volume of requests handled per day or month
- Latency improvements or reliability metrics you achieved
- Languages and frameworks used, such as Node.js, Python, Go, or Java
Trellis uses the phrase "well-tested production services" in the job posting. Mention your testing practices explicitly. Engineers who write tests and care about quality stand out at companies like this.
System Architecture and Technical Leadership
Senior roles require more than coding. Trellis expects this engineer to define scope, set technical direction, and mentor teammates. Your resume should reflect those capabilities clearly.
- Highlight projects where you led technical planning from scratch
- Mention times you wrote technical specs or architecture documents
- Include examples of cross-functional collaboration with product or business teams
- Note any mentoring, code review ownership, or onboarding you led
Do not bury this in soft skills sections. Weave it into your bullet points under real job experiences. Recruiters want to see leadership demonstrated through outcomes, not just claimed in a summary.
Reliability and Infrastructure Engineering
Trellis describes building integration infrastructure that routes, ranks, and attributes provider traffic. That language points to distributed systems thinking. Show that you understand reliability, observability, and fault tolerance.
- Reference uptime improvements or incident response work
- Mention experience with queuing systems, retry logic, or rate limiting
- Include work with monitoring tools like Datadog, New Relic, or similar platforms
How to Tailor Your Resume for This Role
Generic resumes do not work for roles this specific. Tailoring your resume to Trellis means aligning your language with the job posting's vocabulary and priorities.
Start with your summary or headline. Instead of writing "experienced backend engineer," write something like "Senior Backend Engineer with 7+ years building scalable API integration platforms in high-growth environments." That framing matches what Trellis is looking for.
Next, reorder your bullet points. Put the most relevant accomplishments at the top of each job entry. If you built an API gateway that handled millions of requests, that bullet comes first, not buried at the bottom.
Mirror the Job Description's Language
Trellis uses specific phrases throughout the posting. Use similar language naturally in your resume. Some key phrases to incorporate include:
- "Provider integrations" or "carrier integrations"
- "Integration infrastructure"
- "Software development lifecycle"
- "Technical direction" and "project oversight"
- "Well-tested production services"
Do not copy phrases word for word. Adapt them into your own authentic descriptions of real work you have done. Authenticity matters because interviewers will ask you to expand on everything you write.
Address the Insurance or Fintech Context
Trellis operates in insurance and financial services. Prior experience in those industries is a bonus, not a requirement. However, if you have worked in fintech, insurtech, or regulated data environments, say so clearly.
Highlight any work involving sensitive data pipelines, compliance-aware systems, or partner API contracts. Even if your background is e-commerce or healthcare, the patterns often translate. Draw that parallel explicitly in your resume.
ATS Tips for the Trellis Application
Most companies at Trellis's stage use an Applicant Tracking System to screen resumes before a human ever sees them. Formatting and keyword choices affect whether your resume passes that filter.
Use a Clean, Parseable Format
- Stick to standard section headers: Work Experience, Skills, Education
- Avoid tables, columns, text boxes, or graphics
- Use a single-column layout for best ATS compatibility
- Submit as a PDF unless the application specifies otherwise
- Use standard fonts like Arial, Calibri, or Times New Roman
Include the Right Keywords
ATS systems scan for keywords that match job descriptions. Based on Trellis's posting, include these terms naturally throughout your resume:
- Backend engineering
- API integrations
- REST APIs or RESTful services
- Distributed systems
- Software architecture
- Technical mentorship
- Code review
- Testing and validation
- Remote-first or remote collaboration
Place keywords in your work experience descriptions, not just a skills list. Context makes keywords more credible to both the ATS and human reviewers.
What Recruiters at a Startup Like Trellis Look For
Trellis describes itself as moving quickly, experimenting boldly, and building with intention. Recruiters at growth-stage startups screen for adaptability, ownership, and impact above almost everything else.
Demonstrated Ownership
The job posting says this engineer will "own projects through the entire software development lifecycle." Recruiters will look for evidence you have actually done that. Bullet points like "collaborated on a project" will not impress. Write instead about projects you drove from planning to production.
Comfort With Ambiguity
Trellis explicitly says they are "energized by ambiguity." Startups want engineers who make decisions without perfect information. If you have examples of scoping projects with unclear requirements or pivoting technical plans under pressure, include those stories in your resume bullets.
Quantifiable Impact
Recruiters at funded startups see hundreds of resumes. Numbers cut through noise. Every bullet point should aim to answer: so what? Consider including:
- Percentage improvement in system reliability or performance
- Number of integrations built or maintained
- Team size you mentored or led
- Revenue or cost impact of your technical work
Even rough estimates are better than vague descriptions. "Reduced API error rate by approximately 30%" is stronger than "improved API reliability."
Final Formatting Advice
Keep your resume to one or two pages. Senior engineers with extensive experience can justify two pages, but every line should earn its place. Cut anything older than 12 years unless it is directly relevant.
Put your most powerful experience at the top. Recruiters spend less than 10 seconds on a first scan. Your backend API work and leadership experience should be visible immediately, without scrolling.
Use a strong summary of two to three sentences at the top of the page. Frame it around what you bring to provider integrations and backend infrastructure, not a generic statement about your career goals.
