Job description
Founding Engineer – Remote (Ab-Intel)
Salary Range: 180k to $240k
We are looking for a Founding Engineer with 2-7 years of experienceto help build AI agents that automate tax preparation for the largest accounting firms in the US. Abacus is profitable, has passed seven figures in revenue in under a year, and is live in 11 of the top 100 firms. We want a high-bar generalist who makes sharp backend decisions and wants to help scale a product that customers already pay for.
Responsibilities
- Build the core tax-automation platform as a generalist: mostly backend, with some frontend
- Help ship the next major version of the product, a big relaunch planned for early next year
- Make backend architecture decisions on your own, working closely with the CTO and Head of Engineering
- Build our LLM and OCR agent pipelines and turn what firms tell us into product
- Work on new products in tax and in other accounting workflows, such as audit
Key Requirements
- Strong Python skills; TypeScript is a strong plus
- Hands-on experience making backend architecture decisions
- Experience at a venture-backed, fast-growing startup (Seed through Series B) is strongly preferred; long tenures at big tech or slow enterprises are a negative signal
- CS degree strongly preferred (Math or Physics also considered) from a top-50 US school, ideally with a strong GPA
- A builder mindset with high ownership and urgency; side projects and 0-to-1 work are a plus
Work experience
- Experience building 0 to 1 at early-stage, venture-backed startups (Seed to Series B, Y Combinator) or as a founding engineer
- Proficiency in Python and TypeScript
- 2 - 7 years of experience as a software engineer
- Has owned features from design to production
- Experience shipping LLM or agent-based features to production
- Owned backend architecture decisions (classic systems, with LLM features on top)
Nice-to-have
- Experience with document extraction or data pipelines at scale
Education
- CS or related technical degree from a Top 50 US university

Prepare your application
Use the description above to assess your fit for SIVAD Consulting. This checklist is guidance from Resumize, rather than additional requirements from the employer. Imported listings can be shortened or change after collection, so confirm the complete description and current availability before sending an application.
Match requirements to evidence
Identify the responsibilities and skills the employer explicitly names. For each important requirement, choose one example from your work, education, training, or projects. Explain what you did, how you did it, and what changed as a result. Include a measurable outcome when you can support it. If you lack a requirement, describe related experience accurately instead of adding an unfamiliar skill to your resume.
Put the most relevant examples near the top of your resume. Keep job titles, dates, qualifications, and contact details consistent across your application materials. Use the employer’s terminology when it describes your experience accurately; a copied list of keywords does not explain your contribution. A short, specific bullet is easier to review than a paragraph that mixes several unrelated duties.
Check the working arrangement
Confirm the location, schedule, employment type, and any eligibility requirements on the employer’s site. A remote label does not establish worldwide eligibility or flexible hours. If compensation, benefits, equipment, travel, or contract duration are missing from this listing, write down your questions for the recruiter. Do not assume details from another opening at the same company apply to this role.
Review before submitting
Follow the employer’s requested file format and application instructions. Open your exported resume and check that its text is selectable, its sections read in order, and its links work. Proofread names, dates, and contact information. Share confidential work samples only when you have permission, and use an anonymized example when necessary.
Submit through a trusted employer or recruiting destination. If the original listing has disappeared, search the employer’s careers page for the title rather than assuming the vacancy remains open. Save the application date, job reference, and the version of your resume you sent. Those details help you prepare for a later conversation and avoid submitting conflicting information through several job boards.
Review your resume for writing and readability feedback, or browse other openings if this opportunity is unavailable.
