What is a senior software engineer?

A senior software engineer designs, codes, tests, and maintains computer software. While these are your primary responsibilities as a senior software engineer, you may also have supervisory duties. These include overseeing a team of junior software engineers or developers. The senior software engineer title is sometimes used interchangeably with senior developer, and positions for both may share similar job duties and responsibilities. In general, software engineers are distinguished from developers in that software engineers apply engineering principles to software development.

What are some common challenges senior software engineers face when mentoring junior team members?

Senior Software Engineers often mentor junior colleagues, which can be incredibly rewarding but also presents challenges. Balancing mentorship with project deadlines can be demanding, as it requires strong time management and communication skills. Additionally, adapting explanations to different learning styles and levels of experience can be tricky. However, effective mentorship helps build a stronger team and can lead to enhanced leadership opportunities for the senior engineer.

What is the difference between Senior Software Engineer vs Software Developer?

AspectSenior Software EngineerSoftware Developer
CredentialsBachelor's or higher in CS or related field; experience often 5+ yearsBachelor's in CS or related field; entry to mid-level experience
Work EnvironmentDesigning complex systems, leading projects, mentoringWriting code, developing features, debugging
Industry UsageUsed across tech companies, startups, enterpriseCommon in software firms, startups, freelance work
Search & ComparisonOften compared for experience level, responsibilitiesCompared for entry-level to mid-level roles

The main difference between a Senior Software Engineer and a Software Developer lies in experience, responsibilities, and scope. Senior Software Engineers typically have more experience, lead projects, and mentor others, while Software Developers focus on coding and feature development. Both roles are essential in tech companies, but the Senior Software Engineer position involves higher-level planning and leadership.

What are the key skills and qualifications needed to thrive as a senior software engineer, and why are they important?

To thrive as a Senior Software Engineer, you need advanced programming skills, deep understanding of software architecture, and several years of experience in software development, often supported by a relevant degree. Familiarity with tools like Git, CI/CD pipelines, cloud platforms, and expertise in technologies such as Java, Python, or JavaScript are typically required. Leadership, problem-solving, and effective communication are crucial soft skills for mentoring teams and collaborating across departments. These skills ensure the delivery of robust, scalable solutions and drive successful project outcomes in complex technical environments.

Re-posted 22 days ago

Job description

The role: BigHat Biosciences is looking for a Senior Software Engineer to join our engineering team. This role is for experienced engineers ready to own a significant area of our platform as a subject-matter expert, lead epics end-to-end, and shape the architecture and engineering practices that support the design, build, and testing of therapeutic antibodies at scale. You will work closely with engineers, product partners, and laboratory scientists to build and evolve the internal software systems at the center of our science.
This role is leveled as Senior Software Engineer I. At this level, you operate as a subject-matter expert in your area, working with a high degree of independence and regularly leading epics. Candidates with prior experience in biotech, life sciences, or scientific software may be considered with fewer total years of software engineering experience.
*At BigHat we believe in titles that commensurate with skill set, relative organizational impact, and value contribution; more experienced candidates are encouraged to apply, with the understanding that responsibilities and title would adjust as appropriate.
  • Lead projects end-to-end, from PRD through implementation, testing, release, and validation against the customer success metric.
  • Own one or more major areas of BigHat's internally developed, cloud-based platform as a subject-matter expert, and serve as a cross-team and cross-org resource for those areas.
  • Take on net-new, 0-to-1 work from specification, designing interactions between features and the infrastructure that supports them, and producing novel solutions where existing patterns fall short.
  • Collaborate with, and increasingly manage, the relationship with scientists and product owners to translate real-world lab workflows into reliable software, and to iterate on success metrics.
  • Operate and run engineering processes: PRD reviews, stand-ups, PR approvals, and other team ceremonies.
  • Own the quality and outcomes of your work and your epics, including debugging, test failures, and production issues, anticipating next steps and owning the trajectory of major features.
  • Drive technical depth across the codebase, infrastructure, and systems, and actively improve the design and architectural principles the team works within.
  • Design and build high-quality software across front-end (UI/UX) and back-end systems, with system-level expertise in the databases, AWS services, runtimes, and processes that underpin them.
  • Lead and review technical designs and PRDs; contribute architectural direction and surface risks and tradeoffs early.
  • Write, maintain, and raise the bar on automated testing to ensure correctness, reliability, and maintainability.
  • Run code reviews as a routine approver, providing thoughtful, high-leverage feedback that develops other engineers.
  • Diagnose and resolve complex issues across production and development environments, including across system and environment boundaries.
  • Improve internal engineering practices, documentation, tooling, and architecture; help set and transmit appropriate urgency in partnership with engineering leaders.
About You
  • You have a track record of owning features and epics end to end in a production software environment.
  • You are an SME in at least one significant technical area and are reaching to master new ones.
  • You work highly independently and initiate the collaborations needed to deliver work that bridges many parts of the codebase.
  • You balance development, architecture, and process effectively, and help the team prioritize where effort yields the most impact.
  • You communicate clearly about progress, risks, and tradeoffs, and your own outcomes, following issues through to resolution and validating that you've met the customer's needs.
  • You are motivated by building software that supports real users doing complex, high-stakes scientific work.
  • You adapt well as priorities and focus areas shift, and you collaborate effectively with engineers inside and outside your direct team.
Experience
  • 7+ years of professional software engineering experience building and owning production systems, including demonstrated end-to-end ownership of features or epics, OR
  • 5+ years of professional software engineering experience with prior experience in biotech, life sciences, laboratory environments, or scientific software, where domain knowledge meaningfully accelerates impact.
Relevant Tech / Skills
Depth in several of the following, with the ability to make and improve system- and architecture-level decisions:
  • TypeScript, React, Material-UI, Vega
  • Python 3, SQLAlchemy
  • RESTful API design
  • AWS (CDK, Lambda, Step Functions, ECS/Batch, Fargate, API Gateway, Athena)
  • Relational databases (e.g., PostgreSQL), including schema and query design
  • Pandas
  • PyTorch or other ML frameworks (nice to have, not required)
The salary estimated for this position is $198,00 - $215,000 + bonus + options + benefits. Compensation will vary depending on job-related knowledge, skills, and experience. Actual compensation will be confirmed in writing at the time of the offer.
What BigHat Offers:
  • Range of health insurance plan options through Anthem and Kaiser (monthly credit if benefit waived)
  • Dental, and vision coverage through Guardian
  • Additional well-being benefits through Nayya, OneMedical, Wagmo, Rula, and more
  • 401(k) with company match 
  • DTO, two weeks of company-wide shutdown, and 12 company holidays
  • Paid parental leave
