Senior Lead Software Engineer, Full Stack (Bank Tech)
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.
If you thrive at the intersection of strong technical execution, adaptability, and relationship building - and you want impact across the entire bank rather than ownership of a single product - this role is for you.
Key Responsibilities
Technical Execution & Delivery
Own technical delivery on active engagements - writing production code, making architecture decisions, conducting code reviews, and building proto@types 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
Relationship Building & Collaboration
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
Domain Breadth & Bank Context
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
Mentorship & Engineering Culture
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
Engagement Model
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
What Sets This Role Apart
You should apply if:
You prefer breadth and variety over deep single-product ownership - you'll work across payments, cloud infrastructure, testing, observability, and ML in a single quarter
You are energized by earning trust quickly in new environments and delivering results that speak for themselves
You excel at rapid @context switching - onboarding to a new codebase in days, not months
You want organizational impact beyond a single team's roadmap - your work will directly advance the bank's most critical initiatives
