Job Description

As a Senior Lead Software Engineer in Solutions Engineering, you will be an Engineering Lead within Bank Tech's internal professional services organization — a team that deploys cross-domain expertise to accelerate Bank Tech's most critical initiatives. Unlike other roles embedded in a single product, you will build solutions on behalf of product and platform teams across multiple domains and technology stacks. You will own technical delivery on engagements, lead small teams of engineers through complex problem spaces, and produce high-quality, production-ready work under compressed timelines. You will move between high-priority initiatives in a SWAT-style model, rapidly orienting to new codebases and delivering outcomes that unblock teams and de-risk delivery. Our team works on Bank Tech's top priorities: Integration, Modernization, Reliability, Automated Testing, and Machine Learning. You will drive technical execution across these engagements while growing your breadth across the bank's systems landscape — spanning full-stack development, Cloud/DevOps, SRE, and AI/ML.

Job Responsibility

  • Own technical delivery on active engagements — writing production code, making architecture decisions, conducting code reviews, and building prototypes that meet acceptance criteria
  • Lead a small team of engineers (2–5) through engagement delivery, setting technical direction and removing blockers
  • Decompose complex, ambiguous problems into practical implementations with clear milestones
  • Ensure quality across engagements: performance, testability, operability, and security
  • Make pragmatic technology choices that balance engineering ideals with delivery timelines
  • Rapidly onboard to unfamiliar codebases and domains, becoming productive in days rather than weeks
  • Build trusted working relationships with engineering managers, tech leads, and senior engineers on stakeholder teams
  • Communicate progress, risks, and technical trade-offs clearly to both technical and non-technical stakeholders
  • Partner with receiving teams during knowledge transfer to ensure clean handovers and long-term ownership
  • Represent Solutions Engineering credibility through the quality of your work and your ability to earn trust quickly in new environments
  • Develop working knowledge across Bank Tech's systems landscape: payments, account servicing, data platforms, core banking systems, and cloud infrastructure
  • Apply growing institutional context to accelerate delivery — understanding regulatory constraints, deployment patterns, and operational realities
  • Stay current on bank-wide technical initiatives and apply that context to engagement work
  • Mentor engineers on your engagement teams, helping them grow technically and navigate the unique demands of a professional services model
  • Contribute to a culture of engineering excellence, continuous learning, and knowledge sharing
  • Lead by example through high-quality code, clear documentation, and principled technical decisions
  • Operate effectively in a SWAT-style model: rapidly orient to new problem domains, deliver high-impact work in compressed timelines, then transition cleanly to the next priority
  • Typically own one primary engagement while contributing to a second
  • Thrive with variety — this role serves multiple stakeholders across different domains rather than deep-diving into a single product for years

Requirements

  • Bachelor's Degree
  • At least 6 years of experience in software engineering
  • At least 1 year of experience with cloud computing (AWS, Microsoft Azure, Google Cloud)

Nice to have

  • Master's Degree
  • 9+ years of experience in at least one of the following: JavaScript, Java, TypeScript, Python, or Go
  • 5+ years of experience with AWS
  • 4+ years of experience in open source frameworks
  • 2+ years of experience in Agile practices
  • Experience working across multiple technical domains in a consulting or professional services engineering capacity where context-switching is the norm
  • Experience with one or more of the following: distributed microservices, serverless architectures (Fargate, Lambda), event-driven systems, observability platforms, automated testing frameworks, cloud migration
  • Demonstrated ability to onboard quickly to unfamiliar codebases and deliver production-quality work in compressed timelines
  • Strong written and verbal communication skills
  • Ability to produce clear technical documentation and stakeholder-facing materials
  • Experience leveraging interactive AI tooling to accelerate productivity, utilizing capabilities beyond basic code completion

What we offer

  • Performance based incentive compensation, which may include cash bonus(es) and/or long term incentives (LTI)
  • health, financial and other benefits that support your total well-being
