Cambridge, Massachusetts, United States Kensho Technologies Full time

Kensho is a Machine Learning (ML) and Natural Language Processing (NLP) company, centered around providing cutting-edge solutions to meet the challenges of some of the largest and most successful businesses and institutions. We are owned by S&P Global and operate independently. Our toolkit illuminates insights by helping the world better understand, process, and leverage messy data. Specifically, Kensho's solutions largely involve speech recognition (ASR), entity linking (NED), structured document extraction, automated database linking, text classification, and more.

Kensho's Applications group develops the web apps and APIs that deliver Kensho's AI capabilities to our customers. Our teams are small, product-focused, and intent on shipping high-quality code that best leverages our efforts. We're collegial, humble, and inquisitive, and we delight in learning from teammates with backgrounds, skills, and interests different from our own.

As a Senior Backend Engineer, you will develop reliable, secure, and performant APIs that apply Kensho's AI capabilities to specific customer workflows. You will collaborate with colleagues from Product, Machine Learning, Infrastructure, and Design, as well as with other engineers within Applications. You have a demonstrated capacity for depth, and are comfortable working with a broad range of technologies. Your verbal and written communication is proactive, efficient, and inclusive of your geographically-distributed colleagues. You are a thoughtful, deliberate technologist and share your knowledge generously.

At Kensho, we believe in flexibility-first, and give our employees the opportunity to work from where they feel most productive and engaged (must be in the United States). We also value in-person collaboration, so there may be times when travel to one of our Kensho hubs (e.g., Cambridge, MA or NYC) will be required for team meetings or company events.

Kensho states that the anticipated base salary range for the position is 150k–225k. In addition, this role is eligible for an annual incentive bonus and equity plans. At Kensho, it is not typical for an individual to be hired at or near the top of the range for their role and compensation decisions are dependent on the facts and circumstances of each case.

What You'll Do:

  • Design, develop, test, document, deploy, maintain, and improve software
  • Manage individual project priorities, deadlines, and deliverables
  • Work with key stakeholders to develop system architectures, API specifications, implementation requirements, and complexity estimates
  • Test assumptions through instrumentation and prototyping
  • Promote ongoing technical development through code reviews, knowledge sharing, and mentorship

What You'll Need:

  • At least five years of direct experience developing customer-facing APIs within a team
  • Thoughtful and efficient communication skills (both verbal and written)
  • Experience developing RESTful APIs using a variety of tools
  • Experience turning abstract business requirements into concrete technical plans
  • Experience working across many stages of the software development lifecycle
  • Sound reasoning about the behavior and performance of loosely-coupled systems
  • Proficiency with algorithms (including time and space complexity analysis), data structures, and software architecture
  • At least one domain of demonstrable technical depth

Technology You'll Encounter:

  • Python, Django, Flask, mypy, OpenAPI
  • Git, Jsonnet, Jenkins, Docker, Kubernetes

At Kensho, we pride ourselves on providing top-of-market benefits, including:

Medical, Dental, and Vision insurance

100% company paid premiums

Unlimited Paid Time Off

26 weeks of 100% paid Parental Leave (paternity and maternity)

401(k) plan with 6% employer matching

Generous company matching on donations to non-profit charities

Up to $20,000 tuition assistance toward degree programs, plus up to $4,000/year for ongoing professional education such as industry conferences

Plentiful snacks, drinks, and regularly catered lunches

Dog-friendly office (CAM office)

Bike sharing program memberships

Compassion leave and elder care leave

Mentoring and additional learning opportunities

Opportunity to expand professional network and participate in conferences and events
